The LiPo safe charging bag is a simple tool that many of us use multiple times a day and probably take for granted. Nearly every RC company on earth makes a bag of their own, but have you ever wondered where the idea came from? It was the brainchild of Mark Wood. He invented the thing. And he’s still making them. The Original LipoSack is made in the US of US sourced materials. You can find out the history of this seemingly minor, but potentially life saving invention at the LipoSack web site, and while you’re there be sure to check out their products.
