Careful with Leaf batteries, they used air for cooling instead of water which means that most cells show significant capacity loss after a few years.

- epistasis 6y agoIIRC, this is highly dependent on the climate in which they were operated. A battery used in Phoenix may have much bigger problems than one from Pacifica.
- mrgzg1 6y agoIndeed! More than getting ripped off on capacity, I'm super scared of using large capacity lithium batteries in general. Having seen small samsung phones blow up, I'm a little scared and have a lot of fuses and cut off switches.
- belval 6y agoTo be fair, there is no real contest between a good LiFePO4 cell and some Samsung battery as thermal runaway on the former is near impossible in normal conditions.

- walrus01 6y agoThis is why the first/second generation Leaf batteries sell for REALLY cheap from used battery dealers. They're generally in poor condition. As compared to harvesting used 18650 cells in the 2500mAh range capacity from other 'used' sources, and building a DIY powerwall that way.
