Oh, for the thread:

https://bigbattery.com/

It was started by the guy who went to jail for reselling Windows recovery CDs. Looks like they take "bad" batteries, break them down, test and condition the cells and build "good" batteries from them. Might be worth looking into for projects.
Are there any affordable solar charge controllers for this stuff that wont make a 2.5kwh battery pack explode? These packs look to have about twice the energy per Kg as lead acid for a comparable price.

e: I guess I should define my scale. I'm trying to power a 1200watt motor (more like 700watt while running) for ~5% duty cycle at a remote site.
