    I've got around 100+ cells so far, wanting to replace the lead acid batteries in an oldschool dell rackmount ups in my rack. Bit more involved than I'd hoped, but the batteries are so easy to obtain. The risk of burning the house down and killing my family currently outweighs the cool fufo factor, for now.

    Biggest issue is the differing sizes and shapes depending on the device. Lots are approx 16500 but you get the odball square or some tiny thing that's half useless.

    Nah, you just need one controller per type. There are probably some more common types you could focus on.

    I miss the times when you could just scavenge 18650s out of anything from laptops to ebikes. I built a home battery system out of those.
