Contacts on a DeWalt 20V Max (18V XR in Europe) power tool battery. The C1–C4 contacts are connected to the individual cells in the battery and are used by the charger for battery balancing.

Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity.[1] A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing.[2] Balancers are often found in lithium-ion battery packs for laptop computers, electrical vehicles. etc.
