Lithium Marine Battery Replacement for Lead-Acid Systems
1. Longevity and Real-World Performance
- EV-Grade Cells: It uses the same high-end battery technology found in premium electric vehicles, ensuring the kind of stability you just don't get with standard marine batteries.
- Built to Last: Even if you're out on the water every single day, this battery will easily give you 8 to 9 years of peak performance-a massive upgrade over old-school lead-acid options.
2. Lightweight and Tough Construction
- Ditch the Heavy Lifting: Forget the back-breaking struggle of old batteries. You can carry this one with a single hand, which not only saves your back but also lightens the load on your boat for a smoother ride.
- Marine-Ready: It's fully sealed against water and salt spray. No matter how rough the seas or how humid the coast gets, you won't have to worry about internal corrosion or hardware failure.
3. Winter-Ready Charging
- Built-in Heating: Most lithium batteries struggle in the cold, but this one has its own automatic heating system. Whether it's a winter trip or a cold northern climate, it charges and runs perfectly year-round.
4. Smart Monitoring and Reliable Power
- Battery Levels on Your Phone: You can check exactly how much juice is left via Bluetooth. It completely removes the guesswork, so you can relax and enjoy the drift knowing exactly where you stand.
- Steady Power Delivery: The current stays strong from start to finish. Whether you're running a trolling motor or the onboard fridge, it won't lose its kick halfway through the day like traditional batteries do.

FAQ
(1). I Plan to Leave My Lithium Battery Unused for 6 Months. So Can I Store Them in a Box Indoors?
Because Huanduy lithium battery has a low self-discharge rate, so it can maintain up to 90% of the power for a long time. You can charge fully capacity at any time.
(2). Can 12V100Ah Power a 1300W, 11.6A Air Conditioner?
The maximum discharge rate of a 12V100Ah battery is 1280W (100A). The battery can only discharge above this value for a few seconds before the BMS starts. Therefore, it is impossible to supply power for a 1300W air conditioner. However, if you can connect two same model batteries in parallel, then it will be solved.
(3). What Specification Inverter Can I Use on 100Ah?
The 100Ah maximum continuous discharge current is 100A. So the maximum current discharged from a single cell is 896W. You can refer to this value to determine the inverter specifications! Generally speaking, a 1000W inverter is usually the ideal specification for most devices.
(4). Does the 100ah Lithium Battery Come with a Handle?
Our lithium batteries come with a comfortable handle. Huanduy LiFePO4 is lightweight, and it will be more convenient for you to move and install with a handle.
(5). Do Lithium Batteries Need a Dedicated Inverter?
AC-powered appliances and equipment require inverters.
(6). How Long Can a 100Ah Battery Power a 12V Refrigerator?
A 12V refrigerator consumes about 1.3 Ah per hour. According to this consumption value, a 12V100Ah battery can power a 12V refrigerator for about 3 days.
