Highly useful tool as I broke a battery wire before this tool, big hands really aren't a fan of these tiny little circuits. pink so they are easy to find i had a set in black and I lost both of those in long grass. good luck trying to loose these. suitable for the Goosky S1 and OMP M1 2s lipo batterys. please note you will recive what is in picture 2 (no batterys are included.)
