Use Case
- Engine Starting: The 12V 120Ah battery is ideal for smaller to mid-sized marine engines that require reliable power for engine starting. The high Cold Cranking Amps (CCA) of this battery ensures reliable starts, even in colder climates, without the weight and maintenance of traditional lead-acid batteries.
- Trolling Motors: Perfect for powering trolling motors for extended periods of fishing, as the deep cycle design allows the battery to discharge gradually without degrading over time, providing steady power throughout the day.
- House Systems: Suitable for powering house systems in smaller boats, yachts, and other marine vessels. This battery provides efficient energy storage for running lights, refrigeration, fans, and other onboard electrical systems.
- Performance Audio Systems: Ideal for high-performance audio systems on boats, this lithium battery provides consistent, high-current discharge needed to power high-demand amplifiers and speakers without the typical drop in voltage seen in lead-acid batteries.
- Backup Power: This battery can also serve as a reliable backup power source for critical marine systems, ensuring that essential electronics remain operational in case of engine failure or power interruptions.
Why Choose the 12V 120Ah Marine Lithium Battery?
- Lightweight & Compact: Lithium batteries are much lighter and more compact than traditional lead-acid batteries, allowing for better weight distribution and saving valuable space on your boat.
- Longer Lifespan: With a cycle life of up to 5,000 cycles, this battery outlasts traditional lead-acid batteries by far, reducing the frequency of replacements and lowering overall maintenance costs.
- Faster Charging: Lithium batteries charge faster than their lead-acid counterparts, allowing you to spend more time on the water and less time waiting for your battery to recharge.
- Efficient Power Delivery: The 12V 120Ah battery delivers efficient and consistent power throughout its discharge cycle, providing steady voltage output and reducing power loss, unlike lead-acid batteries which suffer from voltage drop during use.
- Better for the Environment: Lithium Iron Phosphate (LiFePO4) batteries are a cleaner, more environmentally friendly option as they don’t release harmful gases or require the disposal of toxic chemicals like lead-acid batteries.
Application Scenarios for the 12V 120Ah Marine Lithium Battery
- Boats and Yachts: Ideal for both smaller and mid-sized marine vessels. This battery can power engines, house systems, and trolling motors, ensuring that your vessel operates efficiently for long periods.
- Fishing Boats: Perfect for powering trolling motors and electronics. The high energy density and lightweight design make it ideal for long fishing trips.
- Watercraft: Can be used in personal watercraft and small boats for both engine starting and powering auxiliary systems.
- Backup Power Systems: Useful for providing backup power to critical systems, ensuring that your boat remains operational even in the event of a primary power failure.

Fitted perfectly on our Ev Si tracker
We are beyond impressed with the performance of these batteries. They're noticeably more powerful than pretty much any other brand we've used in our shop. And honestly the best part about them is that we don't have any warranty issues, after I installs are done our customers enjoy the units and we don't have to service them several times to get it right like we do with other brands. We are very happy at our dealership with Fleet Lithium batteries. We've installed hundreds of them, I'm not sure why they're not more reviews on these batteries but I can only assume because not many people come back to this website to review them. We're at lakesidebuggies.com and we've installed more of these than I can possibly even count. Nothing but praises for this company.
I've got a 2013 Ranger we picked the 51160 ( standard range ) and it's like a brand new machine. Easily double the range much more torque, amd it gets up hills effortlessly. I highly recommend Fleet lithium. We are very impressed
We love our new battery, we are consistently seeing over 50 miles and range, no more mess and no more acid to deal with, and the cart has so much more pickup and speed now. Well worth the money, premium quality, top notch service! Thank you for making a great product!
Swapped into my Badboy buggy in under an hour. The cheap packs I tried before would cut out during heavy use; this Fleet Lithium pack never throttles. I get about 40-44 miles on flat courses.
I installed this pack in my Textron Prowler EV two months ago what a difference! Other cheap lithium packs would randomly shut down mid-ride, but this one delivers consistent power. I'm regularly seeing 42 miles per charge, though it varies with terrain and load.
Fleet is what they said it was: reliable, strong, and no drama.
I swapped out a RoyPow and couldn’t believe the torque boost. Fleet is on another level.
Instant power, zero maintenance. Way better than anything I’ve used before.”
Absolutely the best built Lithium Battery on the market.
The Huge BMS handles the most extreme terrain, without compromise.
I own a Badboy buggy and cheap lithium packs always failed within months. This bundle's decade-long warranty, plus the protective cell gap, ensure it won't quit on me. I average about 41-46 miles depending on conditions.
My Textron Prowler EV had issues with past packs shutting down. Fleet Lithium support helped me update firmware via the app, and now I hit around 42-45 miles consistently.
I was nervous after cheap packs shut down unexpectedly. Installing this in my Textron Prowler EV, the built-in fire suppressor and NextGen BMS gave peace of mind. Saw over 43 miles in mixed driving.
In my Badboy buggy, heavy hills used to kill my cheap pack. With this bundle I maintain steady power and get 40+ miles before needing a recharge.
Installed in my Badboy buggy, I've gotten a solid 44 miles on a single charge cheap packs I tried would die at 25-30. Smooth operation and zero shutdowns even under load.
