NOTE: In the above FMA wiring scheme, when the battery has fewer than 5 cells, the red wire always
connects to Pack positive, and the unused balance (node) wires are left un-connected from the battery.
Always remove unused wires from the Cellpro battery pigtail by gently lifting each pin’s locking tab with a
hobby knife, and pulling the wire free of the housing.
