Gens aceG-Tech High Voltage 15.2V 5300mAh 100C 4S Lipo Battery HardCase with EC5 Plug

Great hard cast, power and longevity.

I've got a lot of batteries from diffent manufactors and this battery failed very quickly on me. I even use a IMARS D300 for all my batteries. Had to return. Maybe I just got a bad battery, happens I suppose.
