Thes battery packs are made from balanced 3350mAh cells connected in parallel and include protection circuitry.  We're very careful about where we source our lipo batteries from and we've tested each version to ensure the datasheet specs are accurate and the safety features work as they should. We stock several different sizes so that you you can pick the perfect one for your project!

All our batteries come with a 100mm lead terminated with a standard 2-pole JST-PH connector. They also include protection circuitry to ensure that they are not over discharged/charged and are protected from short-circuits but you should still take care when using them.
