I have a Rad Rover 6 Plus. Battery wouldn't charge or even show a single bar on display and was not in "transport mode". I followed this guide but had to open BOTH sizes to cut the battery adhesive to be able to slide the batter about 1 or 2 inches as the 10 amp fuse was mounted deeper down on the RIGHT side. Note also that I found a 30amp fuse on the other side (opposite the charge port). It was still okay, but the 10amp fuse was toast. I replaced it and the battery is charging just fine!!!! Why don't they make this any easy fuse replacement. These are $600 batteries that shouldn't be replaced simply due to a 10 cent fuse!
