If you're annoyed at having to use XT60 adapter cables to charge all your odd-ball 2S batteries, I've got the solution. Now you can charge them all using just the balance plug.
PS: THIS DOES NOT WORK for Fatshark batteries with "fan-only" balance connectors. This only works for LiPos with actual, fully-functioning balance connectors.
