I bought a used e revo that came with 2 2s 30c 4500 lipo batteries. but it didn't come with a charger. so I bought an ez peak pus charger. problem is none of the cords that came with it match up with the plugs on the batteries. is there some sort of adaptor I need to get this charging or am I out of luck and need a different charger? the plug on the batteries kinda look like a T. new to electric if someone could point me in the right direction please!! would something like this work?
