One 6v NiMh battery with JST connector and One On / Off switch with receiver type plug.
Battery: Commonly called a “Hump Pack”
These batteries are labelled 3,000 mAh This may be optimistic and they may prove to be of a lesser value. I just copy the specs I am given.
If you absolutely need 3,000 mAh you may be better off purchasing Panasonic, or similar from elsewhere.
Chemistry: NI-MH Capacity: 3000mAh.
PLUS: One Switch: Simple On / Off switch with JST connector to suit battery input and receiver type plug output.
Great combo for planes, gliders, yachts and cars.
