Product Description
Power your entire off-grid life with our 12.8V 300Ah LiFePO4 Battery. With a massive 3840Wh of energy and a heavy-duty 200A BMS, this battery is designed to run high-load appliances like microwaves, coffee machines, and even RV air conditioners.
🏆 300Ah Capacity = True Freedom
One of these batteries replaces three or four 100Ah lead-acid batteries.
- Weight Savings: Weighs only 26kg (Equivalent lead-acid bank weighs over 90kg!).
- Usable Power: Unlike lead-acid, you can discharge this battery to 100% without damage.
- Longevity: Grade-A Prismatic Cells rated for 4000-6000 Cycles (10+ years lifespan).
⚡ Built for Heavy Loads (200A BMS)
Most 12V batteries only have a 100A BMS (limited to 1200W). Our 300Ah Pro Version comes with a 200A Continuous BMS.
This means you can safely connect a 2000W or 2500W Inverter to power your household appliances while camping or boating.
🌍 Ideal Applications
- RV / Motorhome: Run your AC for hours off-grid.
- Solar Storage: Perfect bank for 400W-1000W solar panel arrays.
- Marine: Reliable house bank for yachts or power for trolling motors.
