Does an active balancer drain power from battery that is
Once a pack is balanced does the balancer still use power from the battery? Yes. It can be a little bit, or it can be significant. That''s why, in many cases, charge transfer balancing ("active") is no better that bypass balancing ("passive"), as both dissipate charge into heat.
