Here is some interesting information on the 2018 Nissan Leaf Packs: https://pushevs.com/2018/01/29/2018-...ry-real-specs/

What is the maximum continuous discharge current for the 2018 Nissan Leaf cells?

Not sure, have not seen that listed in any of the specs that I have seen. A module rating is 112.6 Amp/Hr and 3.65 volts nominal X 2 and then doubled again, as there are 4 parallel sets of 2 cells in series. Each module is 2p4s, 112.6 Amp/Hr at 14.6 volts nominal.

Nice pick up!
I worked as a total loss supervisor for a major auto insurance carrier before retiring, one of my duties was reviewing bids before selling salvage.

Thank you Sideways

Well, I caved on the request for the air chisel. He said he needed a new one anyways and he paid for it... It was only $25 with a set of new chisel tips. It was a whole lot easier for sure. Opened the top like a can of tuna. LOL

I disconnected the interconnect cables/jumpers first thing and removed the BMS module, in order to help isolate the HV threat. Now to unbolt the pack assembly brackets and remove the module assemblies. There are 24 modules in this pack, and I verified that there are 8 cells per module.

Here are photos of the interior of the pack, and the removed BMS module.

I’m drooling watching this. Do you mind if I ask how much you paid, I know it was less than $10,000.

The salvage yard knew what they had and they told me the battery pack price new is $12K according to Nissan. They always do their homework before setting a price. Their initial price was $6K + TN sales tax, for $6585.00 total. I was able to buy through my friends body shop in central NC to get rid of the TN sales tax. He emailed them a photo of his NC resale certificate. I had him do the initial negotiating because he's so much better at dealing with salvage yards than I am. Let's just say, I paid less than half of the new price when all of the negotiations were over.

I managed to get the left rear and right rear module assemblies removed fom the pack lower tray, and dismantled. Heavy buggers with 6 double-height modules in each assembly. I am beat! It was a long day already, then having to lift and move those stack assemblies after running out of energy...

Some pics of the 12 double modules, stacked in my living room. Side view, terminal end view, and a view of the steel plates used to maintain clamping pressure on the modules during use.

This would make a good PV storage pack.

Seems like a good deal. Market value is about $300-325/module based on eBay listings I’ve seen. So you can make yourself a 58.8v to 67.2v pack for free after selling off the rest.

AND, unlike eBay, you got 2018 with only a month or so use.
