i have 3 12V 50Ah LiFePO4 batteries in series to get 36V. i did the initial balancing by connecting the batteries in parallel after they were all charged up to 13.4V.
i read that this process needs to be repeated like every 6 month.
so yes at very low voltage <=12V or larger voltage >=14.4V they can be differ by 0.1V-0.4V ( which is my resolution of the small DVM attached to each battery.
question:
i cannot find a BMS that allows to connect the 3 batteries and it manages this series setup continuously as usually is done with individual cells.
