BalancerLand


Welcome to the online resource center and idea exchanging place for users of the Lee Hart/TMSI Battery Balancer kit!

The Battery Balancer is a system that tries to keep the set of batteries in an electric vehicle "balanced" by shuttling charge to the weaker/lower capacity batteries in the pack so that the batteries will all reach empty at about the same time when they are discharged and full at about the same time when they are recharged.

The Battery Cycler is a device to allow testing a battery or cell by discharging it at a constant current and then recharging it.
