4V USB Lithium Batteries and Battery Chargers

Batteries are vital for doing any work away from a mains power source, making tasks in otherwise tricky places simple to complete. Our 4V range of batteries and chargers fit with many other tools in the same system. Our lithium powered batteries have increased storage and a four stage fuel gauge which handily displays remaining power at 100%, 75%, 50% and 25% so you know when it's time to recharge.
