Re: G1 vs G2 Leaf batteries and what to verify from the seller
The only way to truly verify the condition of used batteries is to test them yourself or you are just going off their word. I have tired first gen modules and they still blow doors on lead batts just in cleanliness and weight savings, I wouldn’t be afraid of them. I believe 2016 and ‘17 30 kwhr modules were rumored to be degrading faster than anticipated, but I’ve also seen it argued that was just a software issue and updates fix the problem. My personal opinion on these used modules is to run them like the Nissan Leaf cab drivers do. Generally always charge to only 80%, usually discharge to only 50% or so, and quick charging in between. They seem to be having pretty good luck with them running hard all day every day. Unless you have the ability to pick and choose a matched set of modules out of a pile of them, your at the sellers mercy.
Or buy a wrecked leaf and have gobs of modules!
