Application: The 280Ah Lithium Iron Phosphate Battery has 3584Wh Energy, and can be expanded to 57.3kwh by wired in 4S4P, Perfect for RV, campers, marine, travel trailer, solar power system, motor homes, UPS, off-grid etc.

Lighter but More Power: Our LiFePO4 Battery has an A-class cell with high energy density, which makes it smaller in size and 1/3 the weight of the lead acid battery at the same capacity, much more convenient for you to remove and place it.

·100% Protection: It has a more stable built-in 250A BMS to protect it from overcharge, over-discharge, charge over-current, discharge over-current, short-circuit, cell voltage self balance, high-temp discharge cut off.

20-year Life & 6000+Deep Cycles: contains 6000+ deep cycles, each lithium battery can run for more than 20 years, which is 3 times longer cycles than other LiFePO4 batteries on the market.

ZEM LiFePO4 12V Lithium Iron Phosphate Battery has twice the power, half the weight, and lasts 8 times longer than a sealed lead acid battery, no maintenance, extremely safe and very low toxicity for environment. Our line of LiFePO4 offer a solution to demanding applications that require a lighter weight, longer life and higher capacity battery.
