[SELLING] Seattle: ~1.6kWh worth of Lenovo packs with Sanyo cells.
#1
I have a couple of dozen Lenovo packs that I picked up a few years ago. I've decided I'm not going to do anything with the rest of them, so I want to make sure they go to someone who will. Before posting on my local craigslist & freecycle, I thought I'd make a post here first.

There are ~25 packs, all the same model, with nine Sanyo 2,600mAH cells each. The nominal capacity is ~84Wh/pack, but they are ~10y old and all of them have seen some amount of use (~90 cycles, on average, based on the data I pulled out of them). I'd estimate that they now average 68Wh/each, or 1.6 killowatt hours in total.

It makes no sense to ship them, so I'm looking for someone in the area so we can manage a drop-off or exchange somewhere.

No reasonable offer refused. PM if you are interested.

Curious, how'd you pull the data off the bms?

Using some arduino code I cobbled together and then didn't do much with:

A write up of my cursory analysis of some of the data I got out of these packs.
