Comment Best to reuse and run them down hard (Score 1) 57
There are a lot of lithium battery -ode designs. Reuse first. A 50kWH pack can run at half capacity for a while until all the important stuff gives out. I take worn out IMR batteries (3AH, 15A continuous draw) from vaping and reuse them for flashlights. It's like a nursing home for them.
After they exhaust all the charge cycles, then they go to the recycle bin.
