RC Concept 4S balance charge lead
Coming from RC Concept is their new balance charge harness for dual 2S LiPo battery packs. The 600mm long harness allows to charge two 2S LiPo packs from one charger output, saving a lot of time and making it possible to charge four packs at the same time using a dual output charger. The balance charge wire comes pre-soldered with 4mm charger and stepped 4mm/5mm plugs on the battery side as well as an XH balancer port and 2mm balance plugs. The harness is only usable with dual 2S packs but not a single 4S battery.
