I brought this battery of Facebook. The seller doesn't have good English, hardly replies and lives in another city so I can't get to him. So therefore I came here for help. I have searched all xgo batteries, but none seem to be in this colour and the seller listed it as 48v 13ah, but I suspect it to be 36v for some reason. Please can someone help we with this. It does not say the volts or anything like that on the battery. I have attached a few pics. I would really appreciate any feedback . Thank you.
