Availability of 62kWh packs is extremely limited, because all are takeouts from Salvage Leafs and since I believe this pack is only available since 2018, there is a finite number and the cars are still going for large sums in salvage sales. I wanted for a langer time to upgrade an older Leaf, both as a challenge and as a way to get a long range EV for less money. I already created a longish (100 mi) truck with 2 parallel (used) Leaf packs some 5 years ago but the newer Leaf packs are not as easy to reconfigure for use in a different form factor, so I was more or less stuck with a Leaf to upgrade. Originally the previous owner of this pack (who bought it from a company selling used packs) was asking 11k for it but eventually (after quite some patience) they agreed to a better deal. Part of it was that the pack was damaged in that the shell was torn and thus there was a risk of water intrusion and damage to the pack, which seems not have affected the pack as far as I can tell, but since the enclosure can't be opened (glued shut), I can only judge by its behavior. I did repair the cuts and tears to avoid getting water intrusion while using it. I also arranged to get a battery plug from a 2013+ Leaf to plug into the new pack, because 2011/12 battery control plugs are different. I did not buy the cap to close off the second High Voltage socket, but managed to close it with the same solution I used to repair the damaged enclosure. I did buy longer (metric) bolts to mount the taller pack. I did not bother with new plastic belly pans or the two brackets to mount above the rear axle. Maybe later I will ask a friend to weld an extension to those two brackets and bolt those to the mounting points in the back of the pack. The most critical part of the upgrade is a CAN bridge, which gets inserted between the car and the CAN bus to the battery (in the battery control wire loom) and which translates the communication between car and battery, allowing the car to see the extra capacity and properly talk to the new battery without going into the limp mode when it does not recognise the battery identity. I got mine from Dala in Finland, but there is EVsEnhanced and even local guys who import in larger quantities to get the cost down. Since I am monthly Patreon supporter of Dala, I got discount on the CAN bridge from him. Note that all CAN bridge hardware is essentially identical, I believe it is designed by Muxsan, who does Leaf upgrades in Delft in The Netherlands. It is where my Alma Mater is, so I am proud that he is doing this, even though I did not interact with him directly.
Concluding - with a cheap older Leaf that has a deteriorated pack (mine showed 22 mi range fully charged) that could be had well below $3k (prices have changed since the oil price spike), the 62kWh pack (40kWh should be several thousand cheaper) and the extra acessories, I have a ~250mi 10 year old Leaf for under $12k with several hours of hunting info and a day of actual wrenching. Hope this gives an idea, Cor.
