Segway Hoverboard

This unit's symptoms consisted of no charging or life. Charger tested positive, charger input not damaged or weak. Tested battery unit, completely dead. Dismantling the power pack was a bit demanding, once dismantled, batteries tested. The end result was 80% of cells were dead. Decided to replace the whole lot. Replaced batteries with quality units. Its been a few months the customer is still very happy with the repair work. These units have a bad press, due to cheap batteries and poor charge controller
