Please order this if you already have a battery you want to use with your GoKart. The kit includes the moulded battery cover, wiring, connectors and all the necessary fixings. Simple to follow fitting instructions are also supplied. You do not need to order this if you are ordering a new GoKart, or a replacement battery from us. All the batteries we supply already have this fitted. This kit is suitable for batteries rated between 15 and 22Ah, with a case size of 18 x 7.5 x 16.7 cms (LxWxH).
