Probably one of the best carry-cases that I have. Impact top, Drill/driver bottom. Four batteries, will fit both tools. There are two chargers, one in each case. Dewalt has a pretty good repair service, you can get parts if needed. I've replaced a couple of switches. Note that the high power, permanent magnets, part of the DC motor(s), will attract metal filing, drill hole scrap, especially when drilling, or driving self drillers overhead. Check with you supplier, the batteries eventually will need replaced. A good/very good supplier will recycle the batteries for you, not just throw them in the trash. Recently purchased two new batteries, as a comb set, at one of the big boxes.
Some like a drill bit chuck that uses a key. Drill/Driver pictured has a hand tighten, 1/2" chuck, (largest bit with out a reduced shank).
It also doubles as a hammer drill. Not the best, but with good masonry bits, will drill a decent hole in concrete block for plastic anchor sets.
DC825 Impact driver.
DC 925 Drill/Driver/Hammer Drill
Best to mark the batteries with your name. Many jobs, part of the end of the day routine, is collecting your batteries.
Note that to date, Lithium ion batteries appear to be relatively safe and user friendly. Lithium polymer batteries are different, requiring addition safety precautions. I have yet to see Lithium polymer in power tools. Found in cell phones, model airplanes, and lap-top computers, etc.
