We have 80 x 30AH lifepo4 cells which we will charge at 5-12 amps and discharge at 5-12 amps. The cells are 30AH packs (3x10AH cylindrical cells). They will be arranged in a cabinet in packs of rows or ten. Need a PC design to connect the cells and to provide BMS to ensure cells operate at max. efficiency. The charge voltage is variable from 190 - 395 volts.
As there are 80 cells, the discharge voltage will be 250-270 voltage. The maximum discharge rate needs to be selectable from 6 or 12 amps. Regardless of voltage.
