This is a battery holder for one cell lipo batteries used in RC Vehicles.These batteries are used in Blade MCX, Blade MsR, Parkzone micro P-51, Sukhoi and various other Horizon Hobby Products.It is a challenge knowing what batteries are charged and those that are not.You simply put the charged ones in the rectangular slots and the ones that need to be charged in the center.
