OK, that makes sense, maybe that's why I bought 2 drills, 6 batteries and 4 chargers. :-) Too bad my energy level doesn't keep up!
Actually I saw DeWalt had a lot of cordless tools available for their 18V XPR and I bought various sets to have all my cordless tools battery and charger compatible, the 2nd xrp drill came in a kit with 2 batteries, a charger, and an impact driver.
