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.
Chuckles because I’ve done that several times now. See one on the ground … bam new project.
now you’ve got me wondering how many of those i’d need to wire up a new ebike battery.

That would be a cool ass project … Make sure you use a steel box for when it catches fire. I’d totally do it just for fun.
nah, let’s do tungsten and make the box a heatsink. also heavier as fuck.
The problemis that they are all different so recharging it safely is quite a challange
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.
pfff who needs safety i can ebike AND smoke
do you mean explode? xD
nah, if i tune it right i can let out the magic smoke when i accelerate
At least one
okay, i’ll wire two together and try it. dammit. okay let’s try three. i wish there was some kind of math or numbers…
