One regular drill and small impact driver came in a 4-tool kit with a battery and charger. I then bought a hammer drill, tool only. The large impact is of the lug-nut variety. I have a Jolt bluetooth speak that I really like for the garage. I made the mistake of suggesting my wife use once. I had to fight to get it back. lol. The Kobalt is the exact same type of speaker and cost me $40, whereas the Jolt cost me $60, if I remember right.Holy crap. That's a lot of stuff. A lot of those tools are handy to have cordless as many jobs just need a few seconds of power. Why did you buy multiple drills and impacts? I have a bunch but mainly so I can leave them various places. I wouldn't be buying nearly as many if I had to start the collection again. If you had switched to red, the batteries would have cost more than your entire haul (but I have had good luck with red longevity). I also gave up on yellow due to longevity/reliability issues.
I assume the kit has a charger and you bought a couple spares or you have four chargers? If I was advising people, I would avoid the speakers/radios that are tool linked as I have used them but don't really see the value to have them tied into my expensive battery supply. At 70% off, they may be cheaper than generic stuff.
The three charges all came with various tools, as did 3 batteries. The other batteries were $27 each with my dad's senior discount, lol. His idea.
