NOTE: In the above XH/EH wiring scheme, there are no un-used wires between any of the nodes and/or
pack positive like the FMA wiring scheme. Pack positive continually moves up by one with each additional
cell added to the pack. Always remove unused wires from the Cellpro battery pigtail by gently lifting the
pin’s locking tab with a hobby knife, and pulling the wire free of the housing.
