So I recently heard about from a co-worker at work that Dewalt is going to introduce a new line of tools that use 120v batteries. Supposedly any 120v battery will be smart enough to know if it connects to a 120v tool or a 20v tool and if connected to a 20v tool it will only output 20v instead of the full 120v. I was also told Dewalt will be releasing them in the next month or so. I tried searching the web for information about the new tools but found nothing. Not sure if this is true or not. Tho
