This charge adapter allows you to plug a Thunder Power or Flight Power battery balance connector into a charger such as one made by IMax, GT Power, Common Sense RC, DN power or others that use the standard JST XH style balance port. The adapter plugs into the 6-cell balance port on the charger, and breaks out into the 2S, 3S, 4S, 5S and dual connectors used by the 6S batteries. With this adapter, you get a "One size fits all" module that will work with any battery from 2 cells up to 6 cells.
