This simple little board has capabilities beyond its size. Able to handle 2S-8S packs in its single JST-XH input port, you can use it as a single balance board, or daisy chain multiple boards together to charge packs in parallel. Self-resetting polyfuses ensure that your charger and other packs are protected from each other in case of a short circuit.

A balance cable is needed to hook this board up to your charger; cables are available for FMA’s PowerLab series, GT500, and 10XP, as well as all chargers equipped with standard JST-XH balance ports.
