I would get the jumpers with the terminal ends anyway. Are you wiring him for 24v? or just linking them at 12v? If you wire at 24v and do not have a 24v charger you will have to unhook the jumper!
is this correct? im wired for 24v right now and i still use my 12v charger, derrick helped me wire it up and he said to charge it the same way it always has, i havent had any issues with it either.
