Hopefully I can keep track here, all the 18650s I'm able to save from the recyclers.
I've got lots of ideas for using these. My first attempt will be a starter battery for my lawn mower. I also want to make a couple batteries for an e-bike I will be building later.
So I got a few batteries from around town. Two out of 3 computer shops were happy to get rid of their old batteries. The third flat out refused. I also had some luck with the local e-waste company. There's actually two in town, but only one was helpful. So I at least have 3 sources of batteries so long as they actually have any on hand when I show up.
I got my first batch cleaned up and sorted by voltage:
My iMax charger came in the mail a couple days earlier and I started playing around with settings and battery chemistries. Seems the iMax is rather picky about the voltage of the cell you want it to charge. Most of my cells are too low for the charger to recognise. So I set about trying to figure out how to charge them without the charger.
Here's a video showing how I started. Keep in mind though that I'm an electronics newb, and am probably doing everything wrong. LOL
