EVE MB31 3.2v 314Ah LiFePO4 Battery Cell

EVE MB31 3.2v 314Ah LiFePO4 Battery prismatic cell. The EVE MB31 is a LiFePO4 prismatic cell that follows the EVE LF280k and EVE LF304. These three batteries have the same dimensions, but the EVE MB31 can store more power and has a higher energy density. The cycle life of EVE MB31 can be up to 8,000 times. These properties make this 314ah capacity battery cell a very popular energy storage battery. For the same 20ft. energy storage container, if you use 280ah battery cells, the capacity of the container is usually 3Mwh. However, by replacing it with 314ah battery cells, the capacity of the container can reach 5Mwh.
