Clean dynamo, clean use, and I have the Monster scooter battery 48 volts 1500 amps. You can buy each one separately. The battery price is 200, and the dynamo is 150. Come check it out. If you like it, may God bless you with it. I have many other parts for the Monster scooter for sale. Everything you need is with me, meaning the scooter is complete, disassembled for scooter spare parts, complete.
