Product Cordless tools

Product
I was reading an article about making battery packs for model planes, and the fellow was using a “Pencil” spot welder to weld on the tabs for the battery cells.

If I ever jump to cordless tools, that might be a good addition to allow me to remake my own battery packs.

I gave up trying to install replacement batteries. I just recycle them now. Makita in particular was fussy as hell. Someplace I read that they have a chip hidden in the battery pack that keeps track of battery use. Sort of like Canon or HP printer ink. But I have no real knowledge of it. Just hearsay.

Friend of mine said to try that little guy on 5/16" bolts, sure enough it works.

The local bolt store told me to upgrade batteries to the 3.0 and boy what a difference. But you guys are all saying go to 5.0 or 6.0 batteries?
 
3's will be fine on that impact. You really start to notice the bigger batteries on the higher draw tools like grinders and large impacts. They extra runtime actually makes them more of a usefull tool than a toy that runs out too quick.

That's the amp hours on the battery Dave. It's really only how long they last before needing to be recharged.

It could also be that the higher capacity batteries can supply more raw current but I have never seen any evidence of that.
 
A grinder was my complaint to the bolt store, their answer was the 3's. And it was a game changer on power, that and a skil saw, they're actually usable tools now. Before with the small batteries they were useless
