Does anyone make a standalone or DC powered lipo cell balancer that is capable of 1 amp or similar discharge rates. Some of my cheaper lipos have 1the cell that likes to self discharge and really throws balance out of wack and takes forever to balance. I know this indicates a defective cell and the associated dangers of it, but I have been using them in starter boxes and to power engine heaters successfully without incident. Just looking for a faster way to rebalance packs instead of my current method of charging just the drained cell with jumpers at balance tap.
