Hi... I bought my grandson a powabike.. Euro model I think from all I've seen. Had new batteries.. But need to replace the female piece inside battery pack that accepts the power lead. The male end is just the single male type. Problem is that, although its a small bit that secures with a nut type thing We have no idea what it's called or where to get the right thing from. My soninlaw said get rca like you. D use for music amplifyer.. But I disagree because of ac currant. Any help you can give will be so gratefully received. Many thanks. Rosiem
