Built for professional tradespeople and dedicated DIYers who need extended runtime without the arm fatigue of heavier battery packs.

Best for all-day use in impact drivers, combi drills, and multi-tools, especially when working overhead or on ladders. It features a built-in 4-stage LED fuel gauge so you always know exactly how much juice is left before you start your next cut
