Litime lithium batteries for boats

From a Single Battery to a Complete System: LiTime Builds a Modern Lithium Power Solution for Fishing Boats

Written by N1 Outdoors on . Posted in Blog

For serious anglers, onboard power has never been as simple as buying a battery and calling it done.

From the moment a boat leaves the dock, the trolling motor must provide stable propulsion across changing wind, current, and operating conditions. High-end sonar and fish finders are especially sensitive to power quality and electrical interference, while voltage instability may affect display performance, data clarity, and overall operation. Boats equipped with gasoline outboards require sufficient starting power, while kayak, canoe, and small-boat owners considering electric propulsion must also match the motor, battery voltage, capacity, and charging equipment correctly.

The challenge is that these components often come from different brands and use different voltage platforms, charging requirements, and connection standards. Users must select batteries, chargers, and accessories separately, then manage system integration and installation themselves. When runtime falls short or equipment behaves unexpectedly, troubleshooting and maintenance can become equally complicated.

LiFePO₄ power solution expert LiTime has continued to innovate around the changing power requirements of modern fishing boats. Since introducing its first dedicated lithium trolling motor battery in 2023, the company has expanded its portfolio along the real-world power path of anglers. Over three years, LiTime has developed products covering five major onboard applications: trolling motors, electric outboards, fish finder and sonar power, gasoline outboard starting, and multi-battery charging.

With the official launch of the Argoseeker electric outboard motor series scheduled for mid-August, LiTime is extending its capabilities from energy storage into complete electric propulsion. This marks an important step in the company’s evolution from a battery supplier into a provider of a one-stop marine power solution.

From One Battery to a Complete Marine Power Ecosystem

 LiTime’s marine product strategy was not built by launching a large number of products at once. It developed progressively, addressing one real-world use case at a time.

June 2023: LiTime’s First Dedicated Trolling Motor Lithium Battery

The journey began in June 2023. After researching more than 500 fishing-boat users, LiTime found that many marine batteries available at the time were general-purpose products and were not deeply optimized for the extended runtime, sustained current output, and multi-voltage configurations required by trolling motors.

In response, LiTime introduced the 12V 100Ah TM Trolling Motor Lithium Battery. Its discharge performance and voltage output were specifically optimized for trolling motor use, including support for 60A continuous discharge for 30 minutes to help maintain stable output under higher loads. The relatively flat discharge voltage of LiFePO₄ chemistry also helps reduce noticeable thrust loss as the battery’s state of charge declines.

The battery can be used individually in a 12V system or connected in series as a two- or three-battery bank for 24V and 36V trolling motor systems. It can support compatible models from leading brands such as Minn Kota, Garmin, Lowrance, and MotorGuide, provided that the voltage and current requirements are properly matched.

July 2024: LiTime’s First Dedicated Electric Outboard Motor Battery

As higher-power electric outboards gained wider adoption, users required battery systems capable of supporting higher voltage platforms, greater current output, and more stable propulsion performance. Traditional lead-acid systems are heavy and complex to wire, while many conventional lithium products are not designed for 60V or 72V propulsion platforms.

Inspired by feedback from electric-boat users, LiTime applied its trolling motor battery expertise to the development of the LiTime 12V 100Ah Outboard Motor Battery, launched on July 9, 2024. The company subsequently expanded this into its OBM battery series, including 12.8V 100Ah and 38.4V 100Ah models.

Through flexible series configurations, the batteries can support electric propulsion systems ranging from 12V to 72V. They are capable of 1.5C discharge for three minutes and include Bluetooth monitoring, helping provide lighter and more stable power for acceleration, cruising, and general operation.

August 2024: LiTime’s First Dual-Purpose Starting Battery with OTA Capability

In August 2024, LiTime launched the 12V 140Ah Dual Purpose Battery, combining gasoline outboard starting and deep-cycle onboard power in a single battery.

With 1000 CCA starting capability, the battery can support engine starting while also supplying power to marine electronics and other 12V onboard equipment. Bluetooth monitoring, self-heating, and over-the-air firmware updates further improve system visibility and long-term functionality.By combining starting and deep-cycle functions, the battery helps reduce the weight, space requirements, and wiring complexity associated with separate starting and house battery banks.

In 2025, LiTime introduced the 12V 165Ah Dual Purpose Marine Lithium Battery as the next step in the product line. The major upgrades included an increase in cold-cranking performance from 1000 CCA to 1200 CCA, an increase in capacity from 140Ah to 165Ah, and a total energy capacity of 2,112Wh.The newer model also added an intelligent energy reserve function that can retain approximately 15% of the battery’s capacity for another engine start when the state of charge becomes low. This allows users to extend the operating time of onboard electronics while maintaining essential starting power for the return journey.

December 2024: LiTime’s First 12V/16V Dual-Voltage Waterproof Charger

As fishing boats adopted more dedicated batteries, owners increasingly needed separate chargers for 12V marine systems and 16V fish finder systems. Carrying and managing multiple chargers added unnecessary space, weight, and complexity.

To simplify multi-battery charging, LiTime launched the LiTime 12V & 16V 10A Waterproof AC-DC Lithium Battery Charger on December 17, 2024.The charger supports selectable 12V and 16V charging modes and can charge either 12V or 16V LiFePO₄ batteries. Its IP65-rated housing and 10A charging output make it suitable for use in boat compartments, marinas, garages, and other outdoor environments. By reducing the need for duplicate charging equipment, the charger simplifies pre-trip preparation and improves the management of multi-battery marine systems.

April 2025: LiTime’s First Dedicated 16V Fish Finder Battery

High-end fish finders, live sonar systems, and other marine electronics are sensitive to voltage stability and electrical interference. When these devices share a power source with other 12V equipment, voltage drops and electrical noise may affect image quality, data readability, and overall system performance.

Based on the requirements of advanced sonar users, LiTime launched the LiTime 16V 100Ah Smart Fish Finder Battery in April 2025. The dedicated fish finder battery provides an independent 16V power source for high-performance sonar and electronics systems.

The battery offers stable 16V output, 100Ah capacity, and Bluetooth monitoring, and is designed to support the power requirements of leading fish finder brands including Humminbird, Lowrance, and Garmin. By separating fish finders and live sonar from other onboard electrical loads, the battery helps reduce interference while supporting more stable sonar images, longer operating time, and clearer power management.

From Lithium Power to Marine Electrification

LiTime’s first five product developments established a broader onboard power platform for modern fishing boats. The upcoming Argoseeker series in August takes the next step by extending LiTime’s capabilities from battery supply into integrated electric propulsion.

The first stage of the series will include two models:

  • A1 (24V 700W): Delivers 60 lbs of thrust, with performance approximately comparable to a 2 HP gasoline outboard. Maximum speed is expected to reach 7–10 km/h based on testing with a total boat weight of approximately 150 kg. The system is paired with a LiTime 24V 50Ah LiFePO₄ battery and a 24V 20A charger, forming a compact electric propulsion package for kayaks, canoes, and other lightweight boats.
  • A2 (48V 2000W): Delivers 120 lbs of thrust, with performance approximately comparable to a 5 HP gasoline outboard. Maximum speed is expected to reach 12–15 km/h based on testing with a total boat weight of approximately 300 kg. It is paired with a LiTime 48V 60Ah LiFePO₄ battery and a 48V 18A waterproof charger, creating a more powerful system for larger boats and higher propulsion demands.

Unlike solutions that require users to source the motor, controller, battery, and charger separately, Argoseeker is designed around system-level integration.

Integrated Motor, Controller, and Battery

The Argoseeker series works together with LiTime’s existing lithium marine batteries, combining the motor, electronic controller, and battery into a coordinated propulsion package. This reduces compatibility concerns and simplifies the user experience from installation and charging to operation on the water.

Three-Minute Installation

The system is designed for rapid installation without complex drilling, extensive wiring, or professional modification. Users can complete the installation in approximately three minutes, lowering the entry barrier for small-boat electrification.

Wireless Remote Control and Cruise Control

Argoseeker moves beyond conventional tiller-only operation by supporting wireless remote control. Users can manage direction and speed more freely from different positions onboard.

The integrated cruise control function also helps maintain a consistent speed during longer periods of travel, improving comfort and reducing the need for continuous manual input.

Go Electric Contest Season Two: Sharing Marine Conversion Stories for a $20,000 Prize Pool

LiTime’s products are shaped not only by laboratory development, but also by real-world user experience.

The first Go Electric Contest in 2025 attracted more than 500 entries from users worldwide and generated nearly 3.5 million impressions. Feedback from these projects contributed directly to the development and refinement of the Argoseeker series.

The second season officially began on July 15, 2026, under the theme “From Paddle to Power — Argoseeker Sets Sail,” and will continue through August 15. Participants may submit photos, videos, or written stories describing their boat configuration, conversion challenges, operating experience, or ideas for future electric propulsion.  The contest offers a total prize pool valued at $20,000, with 79 awards across champion, runner-up, third-place, and Spotlight categories.

How AI, 4K, and Next-Gen Processors Are Transforming Modern Fish Finders

Written by N1 Outdoors on . Posted in Blog, Fishing

The depth sounders of your grandfather’s generation used echolocation to transform commercial fishing. They leveraged what was then state-of-the-art electrical pulse generation and sound wave emission to pinpoint cod, herring, and sardines. But those gadgets are transistor radios compared to today’s fish finders.

The advent of CHIRP sonar, the boom in mass-produced microchips, and low-cost high-resolution screens not only make fish finders inexpensive enough to keep onboard recreational watercraft but also sensitive enough to pick out individual bass, walleye, snook, and snapper.

Combining high-speed data processors, “live” transducer video, and AI to interpret all that visual evidence, the systems available today provide boaters with a window to the underwater world like never before. 

How AI is Making Your Fish Finder Smarter

4k fish finder technology

Artificial intelligence now directs how fish finders decipher and display information, filtering out irrelevant noise and zeroing in on the actual targets you’re looking for. Augmented by sonar precision, sophisticated mapping data, environmental inputs, and historical patterns, AI enables some fish finders to predict where the next productive fishing zone will be.

Take for instance Simrad’s Sonar AI. It can almost be considered a virtual assistant living in your fish finder. Instead of having to stare at your MFD’s screen and wait, Simrad’s Sonar AI watches the sonar returns for you. As soon as it identifies a fish, it will automatically drop a special marker for you on your screen and sound an alarm.

And like all other AI models, it continues learning. When you mark a spot on the map, the system makes note of the conditions and environment. Then, when similar patterns present themselves later, the system makes the connection and emits an audio alert. These signals become more accurate as the machine learns which signals represent game fish, bait schools, cover, and water temperature bands.

As AI intelligence and onboard computing power continue to grow, AI is expected to play a larger role in sonar interpretation, route planning and environmental awareness.  

Faster Processors Mean a Smoother Experience Out on the Water

If you’ve ever used a fish finder that took several seconds to load when you zoomed in on part of a map, you understand how frustrating this can be. One of the biggest advancements in modern fish finders isn’t immediately visible – it’s what’s powering the machine.

4k fish finder map

Today’s fish finders feature powerful 6-core and 8-core processors, capable of running multiple tasks at the same time, including live sonar, CHIRP sonar, side-scanning, radar overlays, detailed charts, engine data, weather layers and navigation systems… without any lag. Up to seven times faster than older models.

Menus open and respond immediately, charts load up right away, and sonar updates feel real-time. Switching between applications is a breeze. When paired with modern transducers, these processors can interpret detailed sonar information clearly and stably, even at high speeds and deep ranges.

Next-Gen Sonar: 360-Degree Live Views and Ultra-Wide Beams

360 sonar fish finder screen

Up until now, live sonar was like a flashlight beam, only allowing you to see where you pointed it. New transducers, such as Lowrance’s ActiveTarget 2 XL, network two HD transducers together, unlocking a 360-degree view. This allows you to have a live, moving video of the entire radius around your boat

Another recent improvement is the elimination of the need for a “black box” in order to get high-definition live sonar. The black box is a large silver processing module inside a dry storage compartment, running heavy power cables to your batteries.

Garmin’s newer transducers eliminate the need for a black box altogether, moving the processing into the transducer itself, and allowing you to plug the transducer directly into the fish finder / MFD and power source. Less battery drain, and less clutter, while providing you with HD images.

Another advancement in transducers is ultra-wide beams, such as Airmar’s 73-degree Ultra-Wide Wave. In the past, most transducers had a narrow, 15-degree cone, covering only a small circle on the bottom. Airmar’s newer transducers shoot a massive 73-degree wide beam, giving fish nowhere to hide.

Having a 4K television in your living room has lost some of its novelty, but bringing this crystal clear screen technology to wet, sunny, rainy, or foggy conditions is a much more impressive engineering feat, and one we’ve reached. Now MFDs from major marine brands bring true 4K resolution screens. 

With four times the pixels as traditional HD screens, these newer fish finder panels allow you to better differentiate between underwater structures and fish, for instance, being able to easily spot a fish next to a submerged tree branch.

Split screens are now easier to use, with each section clearly displaying the information, even in direct sunlight.

A New Era of Fishfinding

If you’re wanting to spend more of your time catching fish, today’s fish finders have the technology to allow you to do just that.

Newer fish finders and transducers are not just about getting a prettier screen or a couple of new features. This powerful, cutting-edge fishfinding technology allows you to clearly see more of what’s beneath the water and is becoming like your own personal fishing assistant armed with data, learning how you like to fish, and showing you where to find more fish. Your boat’s electronics are now doing the heavy lifting for you, and allowing you to filter out junk data – saving you time, so you can spend more of it catching fish.

Backcountry Ready: Hunting Fitness, Preparation and Recovery Framework That Keeps Hunters in the Field

Day three of a backcountry elk hunt is where most hunters find out the truth about how well they prepared. 

The first morning was adrenaline. The second day was determination. By the third morning, when the alarm goes off at 4:30 and the legs that climbed six thousand feet of elevation over the previous two days are registering their opinion about the situation, the gap between the hunter who prepared and the one who just showed up becomes visible in a way that no amount of willpower closes. 

The elk don’t care. The mountain doesn’t care. And the bull that’s working the ridge above camp is going to require another two miles of hard hiking to close the distance. 

Whether your body is ready to make that happen is a question you answered months ago.

Western elk hunting is not a casual physical undertaking. A serious public land elk hunt can involve daily elevation gains of two thousand to four thousand feet, pack weights of fifty to seventy pounds when packing out a successful kill, miles of off-trail travel through deadfall and steep terrain, and all of it at altitude where the aerobic demand is meaningfully higher than the same effort at sea level. 

The hunters who come home with elk meat in the cooler year after year are not the most naturally athletic ones. They are the ones who respected what the mountain requires and built themselves to meet it.

What the Mountain Actually Costs Physically

The muscular demands of backcountry hunting are specific in ways that general gym fitness does not fully address. Steep uphill hiking under a loaded pack recruits the posterior chain, hip flexors, and calf complex under sustained eccentric load in patterns that flat-ground running and standard strength training leave underprepared. 

The knee stabilizers absorb forces on steep descents that accumulate into significant fatigue over multi-day hunts. The shoulder and upper back musculature carries the pack weight continuously in ways that create a sustained postural demand no standard pressing or pulling exercise quite replicates.

Add the recovery demands of sleeping on the ground at altitude, where sleep quality is reduced and the temperature swings that cool nights produce keep the body working to maintain core temperature through the night, and the daily physical deficit that a serious backcountry elk hunter accumulates becomes significant. 

mountain in distance in winter

Temperature swings are more than movements in degrees, they are a physical demand on the body of a backcountry hunter.

By day three or four of a hard hunt, the question of whether a hunter can close a stalk is not just a matter of hunting skill. It is a matter of physical reserve.

The pack-out after a successful kill represents the single most physically demanding component of an elk hunt for most hunters. Quartering and packing out a mature bull elk involves multiple loads of seventy to ninety pounds or more over the same terrain that was challenging to navigate unloaded. 

Hunters who have not prepared specifically for the strength and muscular endurance demands of a pack-out discover it in a way that is unforgettable. Those who have are the ones who make it out in reasonable shape and are ready to hunt again the following season.

Fueling the Hunt: Nutrition Before, During, and After

The nutritional demands of a physically demanding multi-day hunt substantially exceed what most hunters eat in their normal daily life, and the appetite suppression that altitude and sustained exertion produce means that the deficit between what the body needs and what the hunter actually consumes can be significant. 

The hunters who perform most consistently through day four and five of a hard hunt are the ones who make deliberate nutritional choices rather than relying on appetite to guide their intake.

Protein is the nutritional variable that matters most across a multi-day hunting trip. Muscle tissue stressed during sustained hiking, climbing, and packing weight is repaired during the night if adequate protein is available, and the quality of that repair determines how the body performs the following morning.

High-quality clean whey protein packs efficiently for backcountry trips, mixes with cold water, and provides the complete amino acid profile needed to support overnight muscle repair when the body is trying to recover from the day’s demands in time for the following morning’s hunt. A packet mixed into a water bottle after the evening camp tasks are done takes thirty seconds, and addresses the single most important nutritional input of the hunting day.

Caloric density matters on backcountry hunts where every pound of pack weight is deliberate. The most experienced backcountry hunters have their food strategy dialled in over years of trial and error: enough carbohydrates for daily energy output, adequate fat for sustained fuel during lower-intensity terrain coverage, and protein targeted specifically at the overnight repair process, rather than incidentally met through whatever happened to be in the food bag.

Planning the protein component of a backcountry food strategy as deliberately as the gear list is one of the habits that separates hunters who come out of a hard week ready to go again from those who need a full week of recovery.

What Research Shows About Protein and Prolonged Physical Demand

A study published in the Journal of Strength and Conditioning Research examining physical performance and protein intake in athletes undergoing sustained high-load physical activity found that those meeting elevated protein targets above 1.6 grams per kilogram of body weight daily showed significantly better preservation of lower body strength and power output across multi-day physical demand periods compared to those at standard intake levels. The researchers noted that the protective effect was most pronounced in the later days of sustained effort, with the performance gap between adequate and inadequate protein groups widening rather than staying constant across the testing period. 

For a backcountry hunter on day four of a hard elk hunt, this is precisely the window where physical reserve determines whether a stalk is executable or whether the body has nothing left to give.

The same research found that muscular damage markers were significantly lower in the higher protein group throughout the testing period, which translated to better functional recovery each morning. 

elk in the backcountry

On a backcountry hunt where the morning hunt window from first light to mid-morning is often the highest-probability period for elk activity, arriving at that window in better physical condition is a direct performance advantage. The hunter who is moving well and thinking clearly at first light on day four has a fundamentally better chance than the one who is stiff, sore, and operating at reduced capacity.

Building Backcountry Fitness: What Actually Transfers

The most common mistake serious hunters make in their fitness preparation is doing too much of what feels like hunting fitness and not enough of what actually transfers.

Running is the most common choice, and it builds a cardiovascular base that helps, but it does not prepare the specific musculature and connective tissue that loaded hiking, steep descents, and pack-out demands place under stress. 

The hunters with the most consistently successful backcountry seasons build their fitness around weighted hiking, single-leg strength work, and posterior chain training that mirrors the actual demands of the mountain.

loaded backpack

Loaded hiking with a weighted pack, progressively built up from 25 to 50 to 60 pounds across the preparation months, is the most specific physical preparation available for a backcountry elk hunter. The hips, ankles, and knee stabilisers that carry a heavy pack across broken terrain adapt specifically to that demand and only moderately to any other training modality. 

Three to four weighted hikes per week in the three months before a season, combined with two weekly strength sessions targeting the posterior chain, produces the physical capability that day three and four of a hard hunt require.

montana mountains

Elevation gain should be tracked and progressively accumulated during the preparation months. A hunter targeting a high-country Colorado or Montana elk hunt who has not regularly hiked at elevation before the season will feel the altitude impact more severely than one who has been accumulating elevation gain across their preparation. Where geography permits, hiking local terrain with elevation is advantageous. If that’s not possible, stair climbers and stadium stairs with a weighted pack are the best available approximation.

Recovery at Camp and After the Season

Recovery during a multi-day hunt is a different challenge than recovery in a normal training context because the options are limited. The tools available in the field are: sleep quality, nutritional input, and whatever the hunter has chosen to pack. This is why the habits built at home in the weeks and months before the hunt matter for performance in the field. A hunter whose body is adapted to deliberate recovery inputs produces better results from the limited recovery available at camp than one whose body is not.

Post-season recovery is where most hunters underinvest. A hard week of backcountry elk hunting, culminating in a pack-out, is a genuine physical event that leaves the body requiring meaningful recovery time before the next demanding physical undertaking. The connective tissue stress of sustained hiking under load, the muscular fatigue of a full pack-out, and the accumulated sleep deficit of a week at altitude all require deliberate recovery inputs to resolve completely.

Hyperbaric oxygen therapy has a specific evidence base for the recovery of soft tissue stress from sustained physical load in outdoor and athletic contexts. The pressurised oxygen environment supports cellular repair in muscle and connective tissue at a rate that standard rest cannot replicate, which matters for hunters who want to process what the season demanded from the body and return to full physical readiness for the following year. A personal hyperbaric chamber brings this recovery capability into the home environment, allowing serious hunters to run post-season recovery protocols without clinic scheduling or travel. For hunters who take their preparation as seriously as their hunting, it is a natural extension of the same investment in being physically capable of meeting what the mountain demands.

The Hunt Starts Now

The elk season that delivers what you have been planning for opens on a date months from now. The physical condition you bring to that opening morning is being built or neglected in the decisions you make between now and then. 

The hunters who are still moving well, thinking clearly, and executing on day five of a hard backcountry hunt did not get there by simply hoping they would hold up. They prepared specifically, fuelled deliberately, and recovered intentionally across the months that preceded the season.

elk calling in a bog

The mountain does not grade on effort or intention. It simply presents the terrain and the elk and lets the preparation speak. Building the physical foundation that lets you say yes to the opportunity when it presents itself, on day four or five, in steep country, with a bull in shooting range and two miles of hard ground between you and camp, is the work that makes the difference. That work is available to anyone willing to do it, and it starts long before the season opener.

The best elk hunters are not the most naturally gifted athletes. They are the ones who took the physical side of hunting as seriously as the scouting, the shooting practice, and the gear selection. 

Treating preparation and recovery as part of the hunt rather than as a separate lifestyle consideration is what separates the hunters who consistently fill tags from the ones who run out of physical reserve before the opportunity arrives.

Prepare well, and hunt safely!
