Cordless power tools are awesome because no matter where you are, you never have to worry about your power source. But, the frustrating thing is that different tools have different voltages, so I end up with tons of batteries and charges clogging up my workspace.
DeWalt has come out with an inventive battery system called the FlexVolt Lithium Ion Battery Pack, which changes voltage when you change tools. So, it’s compatible with 20-Volt, 60-Volt and even 120-Volt MAX DeWalt tools.
It is available at The Home Depot.
