Double Horse 7.4 volt 800mah rechargable battery pack 703048mp fbc7j25

Plugged right into my RC helicopter to replace the original dead battery that wouldn't hold a charge. Only issue I had was letting my 3yr old at the controls while flying outside at night. The battery held up well, but its difficult to charge still sitting in a tree in my backyard.I only used the 2-wire cord for charging and power to the helicopter, and it worked flawlessly.

works and it arrived on time
