• BL20 balancers are designed to support GBS 20Ah cells.

When multiple Li-ion cells are connected in series forming a battery pack, it is important to maintain capacities of the cells within a tight distribution. This is achieved by implementing balancing circuits, which discharge cells at high SOC levels while allowing cells at low SOC levels to be charged further. This results in a higher overall pack capacity. Cell balancers do not replace a BMS system that is required to protect cells from over-charging and over-discharging. Cell balancers can be added to compliment a BMS that does not come with balancing function.
