Review on Uxcell Resettable Fuse Radial Polyswitch by Larry Blanco

I used these current limiting and resettable fuses on my hoverboard's internal batteries. This is done to prevent overcharging the old hoverboard battery. Just connect it to the red positive battery post. Do not overcharge your hoverboard batteries and unplug the charger when fully charged for your safety and peace of mind! Follow the manufacturer's instructions!
