Hi, Need some help with my son's 12.5r, the bike will run perfectly for about 30mins after that the power will keep cutting in and out, have recently done a lipo conversion and there is still plenty of juice left in the batteries when the cutting starts, any ideas? Thank you.

Was it a home made lipo conversion or pack from boost bikes. If homemade then possibly issue with the battery monitoring system? sure someone with electrical know how will explain. Only similar issue we had with an oset it was the controller/throttle unit kept intermittently cutting out. Had to replace it
