Self balancing behaviors exist for cells in parallel in a battery pack due to the fact that voltages of individual cells tend to be uniform. In self balancing behavior, cells of different capacities inter charge/inter discharge themselves under low C rates. Self balancing is influenced by temperature, C rates and relaxation time at high SOC. 2 Balancing Management …

If a large battery bank is needed, we do not recommend that you construct the battery bank out of numerous series/parallel 12V lead acid batteries. The maximum is at around 3 (or 4) paralleled strings. The reason for this is that with a large battery bank like this, it becomes tricky to create a balanced battery bank. In a large series/parallel battery bank, an imbalance is …
