There are instructions all over Youtube for making battery packs from generic LiPo cells. You need a 3D printer to make the case and then you need to build a spot welder to wire the batteries together. Soldering does not work.
Back when I owned a sailboat some years ago I used to keep a cordless drill on it and the battery technology was NoCad and the drill's performance was horrible. I bought two cordless drills before I figured out the battery tech was not up to the task. This was back in the NiCad days. So I solved the problem by buying a corded drill and installing a 1000W inverter on the boat connecting it to the boat's bank of lead acid cells (6 golf cart batteries) So I guess I had a Lead-Acid powered drill? (and a lead acid powered microwave oven too) I'd never make a power tool battery pack but my reasonfor owning machine tools is robots. So g=far I'm been using LiPo batteries that are designed and sold for quad copter drones as (for obvious reasons) they seem to have the best power to weight ratio and lowest cost per kilowatt hour. But these batteries are like playing with gasoline but worse when they design to burn, they continue to burn even if you toss it in a bucket of water. Those cylindrical cells (that are used in tools, cars and power walls) are safer to use. I'm going to build a spot welder one day.
