Connector for WC4 charger (2 cell packs to use serial charging capability) (R1EM-connector-serial-2)

Connector for WC4 charger (2 cell packs to use serial charging capability) (R1EM-connector-serial-2)

Connector for using parallel charging.

If a battery pack is only serial wired, use this connector to make WC4 charger to charge lithium polymer pack serially. If a lithium polymer pack has only one out coming connectors, chances are that the polymer battery pack is only serially wired.  If a lithium polymer pack has 2 out going wires, the lithium polymer packs are likely to have parallel wiring done in addition to serially wired.
