I don't know how you would determine ahead of time if a Leaf pack has much capacity remaining. There is a lawsuit out because Nissan did a poor job of pack design where high temperatures are seen. Some packs in hot climates have lost half their capacity in less than 2 years. They needed to have a cooling system. Something to consider when repurposing them yourself. You never want tot charge them fully, or you need to keep them cool when they are charged fully. This the damaging condition - fully charged, too hot. It has nothing to do with charge or discharge rate. You may want to only buy the packs for not much $, or get some sort of warranty - unlikely for DIY applications. Maybe if you knew the donor car was never operated in the deep south...still is is more dicey than woith other packs.
The Leaf I bought has 18K miles on it, so I expect the pack has some (hopefully minor) capacity loss. It is a 2013 model, so I believe that has a slightly upgraded battery chemistry that deals with the heat better. I (and the leaf) is in/from Atlanta, so that's probably the deep south ;>
However, the price was right for a "used" pack, as I'm getting a 24kWh pack for significantly less than the equivalent new price of lithium cells. (I'll probably post some info about buying a salvage Leaf later on..)
I also hope to be able to sell some of the other parts of the car that I don't plan on using to offset the expense.
