Wow - jealous! Maybe.

It's going to be a real challenge sorting out all those cells.

Before doing anything else, you're going to have to get the specs on them, and design/build some kind of test rig to sort the good from the bad.

Since it sounds like they're going to be of varying quality, you're also going to need a good battery management system (BMS) to prevent over-discharging.

I have an idea that I may be able to get my hands on an ongoing supply (trickle) of lithium batts - power tool size packs. I know someone who runs a tool/appliance repair/warranty depot for a major tool/appliance manufacturer. I have to remember to ask him about it this spring when I get back to Ontario.

Mind me asking what this company does that it's chucking out piles of batts?
