I am not an attorney, but it seems to me that licensing your technology to an independent US company would insulate your company from any installation liabilities that might arise in the US. You would still have product liability - the product has to work as advertised and any product defects are on you, but you have that liability now.

Re: Battery Upgrades are very possible

How would I be sure of the vintage (and capacity!!) of a pack that has been separated from it's car already? Does anyone have pictures from when they dropped their 30 or 40kwh pack? or a list of the battery assembly part numbers that have been used over time? I'm concerned about telling the difference between the 13-15 24 kwh, and later 30, 40 kwh.

If I'm looking at a pack that is claimed to be from a 2018 vehicle, but no vin info available, I should be able to tell from the part number on the pack. What is a valid part number from a 2018+ 40kwh pack? Or if anyone has won the junkyard lottery, have you seen the p'n on a 62kwh pack? :o I don't really want to buy a 24 or 30 kWh pack by accident. :(

I found some current service part numbers online, 'Battery Assembly'
 295B0-5SA9B ( $11-12000 !!! ) this must be 30kWh? but don't find any 'replaces' part numbers

The 11-12 ones do list the superseded parts these would all be 24kWh. ($7800 !!)

Reading this document about Understanding Nissan part numbers, and looking at the above numbers gives me some ideas, but nothing clear. The 6-8 digits 'part type number' could be associated with the vehicle it was first used on, and the 9-10 digits are a 'distinction' number, ie: what's different about it. So I would guess 6 digit to be >5 like 7 or 8, and maybe 9th digit >9 (like A,B,C)

Best way to go about this is to hook it up to CAN, 12V and IGN and read out the CAN bus. I believe there's a wolftronix box that does this already. I myself use a homemade contraption. That is, if you have physical access to the battery.

There's also a sticker on the pack that says the capacity on a number of packs but not all. There seem to be a few variants.

Optically from the outside, it's extremely hard to tell as the 30 and 40 have identical shapes. There are some tiny differences in the rear mounting bracket that you can see here:

Furthermore the 40kWh pack is exactly 303kg, whereas all other packs are less than 300kg.

Just so you're not just hearing it second hand: yes, we have 10 cars driving around with extender packs already and one 'ultra-leaf', i.e. the 40kWh+extender+3ph charging (all the upgrades we're offering right now). We're installing about one more car per week now and ramping up to full production soon (tm). Over the past few months we've been ironing out lots of bugs and we are pretty confident in the product by now. All that's left is type approval and documentation before we can call it final.

It's going to take a while before we can offer this in the US and Canada. Our insurance expressly excludes US/CA because of liability concerns, so we'd have to offer it uninsured as a DIY at-your-own-risk kit, but even then it might be iffy. Best is probably to find a full producer, installer that licenses our tech or something like that.
I'd be happy to purchase a step by step instructions on how to build and install myself a system to gain 40-60kKVH for my 2013 Leaf (USA).

Like Mux said, there are stickers on every battery with the capacity on it. This is what a 40kWh sticker looks like

62 kWh Plus packs are about 5mm taller than the 24/30/40 kWh packs. There's likely no easy way to swap a Nissan 62 kWh into one of the older cars.

IIRC, they are 5mm taller, not 5CM. That makes a difference.

Whoops, looks like the right number is 5mm.
