Bms battery balancing how much mv
For LiFePO4, set the balancing voltage to 3. 2 V for a couple days, it should balance. Battery balancing maximizes the usable capacity of the pack, prolongs the life of the cells, and averts safety problems associated with overcharging or over-discharging by ensuring all cells in the pack have the same SOC. Balancing can be dissipative or nondissipative (dissipative: energy is wasted in heat; nondissipative: energy is transferred and therefore it is not wasted). Dissipative. One thing they're now able to do is to calculate out the capacity of individual bricks of cells (96 in the 85/90/100, 84 in the rest) based on a ton of factors and compute this in near real time, in a full range of conditions, with almost magical accuracy.
