If not for lack of funds I would love to have 2 of these for my G-van.
Same here: I'd love to have a lithium pack for my EV! The big question
in my mind is whether they are any good. They are being sold as-is,
without warranty. I've been burned before on such battery "deals".
I'll have to wait for someone else to go first, and tell us what they
actually get.
A few notes:
1.) these are reported to be the same cells as found in the Leaf. This
might make them convenient as a way to create a "48 kWh" Leaf, if one
can find space for them. (Or useful as parts for rebuilding Leaf packs.)
2.) the cells in the 2011-2013 Leaf are demonstrating themselves as not
being highly heat tolerant, and thus are losing capacity faster than
projected in hot climates
3.) it looks like these cells were part of the Better Place bankruptcy
liquidation in Israel. Were these cells sitting in Tel Aviv for a while?
If so, one might expect there to be some heat and time related degradation.
