We aren’t the first to seek a better use of batteries. Think about power tools that have a universal battery system. Each device powered by the same battery is another opportunity to save. Save the environment, save space, save weight, and perhaps most important to you: save money. After all, batteries often make up over 50% of the cost of these types of products.
