I'm afraid I don't know. I go by either the manufacture date on the driver's side door sill sticker, or the vehicle history report, which should always include the date of manufacture along with the in-service date upon which warranties are usually based.
Battery Upgrades are very possible

Where did you get quoted that much? One of my buddies was quoted over $8,000 for a 24kWh pack from Nissan.

that is old news. The "current" price is actually $4500 after the "required" exchange plus parts (required on all 2011-12, some 2013's its a few hundred) and labor.

A new battery was $8000 plus till about the start of 2020.
Nissan must have figured if they didn't offer reasonably priced replacement batteries then people would buy more new cars. Then they saw the aftermarket eating their lunch and decided to join the party.

Does anyone have the part number on the 24 kwh pack? I remember seeing it here and looked at the online price and it was <5k$, but can't find it now. TIA.
Thanks. I looked for that here, and failed to find it.

This one is interesting! Looks like 64kWh of new cells fit into an original 24kWh pack shell. Wow, that's cool.

Yeah I've been speaking with the creator, Jesus. This is some really cool stuff, and will make that leaf really usable. I'm helping him with the instrumentation correction now, an inherent issue when doing bruteforce upgrades.

The lack of vertical mechanical barriers is a little concerning. Is he using a re-programmed original BMS?
coleafrado said:
Yeah, the only way to make a bruteforce upgrade tolerable is to use a Muxsan CAN bridge and add more GIDS to the communication between battery and car. It is inferior compared to using a natively bigger BMS such as the 30/40/62kWh BMS, but it will be better than nothing. More explained here. https://github.com/dalathegreat/Nissan-Leaf-Bruteforce-Upgrade/

as far as i know the bms remain the same of the 24kw, e.g. for the the same number of battery modules. No idea if Jesus planned to reprogram it to fit new battery protections paramters.

Since the pack remains an item you cannot directly purchase, part numbers will be hard to find along with any associated pricing. The current "sale" price is apparently not an official price as some dealers tell me the catalog (that we can't see) still lists the pack at $6 K "after" exchange.

I'd like to make changes at current sensor's signal. What's type the current sensor Leaf hi voltage battery: analog or digital? I'd like to integrate CAN-bridge with current sensor corrector.

Check out this fork of the bruteforce upgrade, they are constantly improving it https://github.com/DanVidLop/Nissan-Leaf-Bruteforce-Upgrade
This was used to integrate a 64kWh battery with the original 24kWh LBC
The renovables del sur guys in Spain have a new video out showing their new battery replacement.
https://www.youtube.com/watch?v=b4a_HJQ-Yd4
They appear to gut the entire existing pack and replace it with new cells. Not sure what they use of the existing BMS and what-not. Looks like they are able to fit in 64 kWh into the new pack.
Says they are shipping to Europe and Mexico, US to stay tuned. https://evbatteryrebuilds.com/en/ev-battery-rebuilds/

They use the original BMS. Does not change battery topology, but only chemical and capacity bue voltage remain the same for each module.
as far as I know here is not BMS reprogramming... just used the original one.

Great find and post!
Some musings:
A true 120 mile range would work for me in a (2011-2015) Leaf. So..... what if economies of scale allow this to take off in South Texas? A SWAG for me could be (comments requested as it's probably simply a WAG!):
- Realistic value of such a Leaf with 8 bar or less battery - say $4000 for solid condition except worn out battery, IF I had to go out and purchase
- Sell the old battery for $1000 or some type of realistic "credit"
- A local "evbatteryrebuilds" installs a new ~34 kWh LG battery pack - $10,000 all in with GOM "fix" and all battery swap labor/materials as part of deal
- With all in of around $13,000 to $14,000 I'd have a Gen II Leaf that would hopefully go at least 100 miles for several years with low degradation
Still not sure I'd go for it, or continue to look for a 2016 Leaf for around $11,000 - $12,000 with either a great battery OR one that will be replaced under warranty.
IMO If you could get a good condition (say 2012 or 2103) Leaf and the LG battery for $10,000 all in, likely a no-brainer, however that would require some serious reduction in the cell pack costs.
Can this eventually happen? The video "prototype" indicates that it's real rather than Fenix Power's hype. If so, I might be just a matter of time and demand from all the Leaf's out there!

I personally think its better to stick with LEAF packs. Moving to 40 kwh is available thru out the country. But my real question is how many application of these LG cells exist without TMS?
Since posting this, 3 more have started up and there are "rumors" (places claiming to do this but I have yet to see the result of any of their work on social media) of more.

After watching the "LG install video" from evbatteryrebuilds, it appears physically, they are doing the conversion. I'd sure like your opinion on the reality of pack construction, connector viability (appears quite "home built"), vibration resistance, heat dissipation, re-wiring techniques, BMS fit for service, potential CAN bridge success, etc. etc. The fact that they had no safety process and used a fork lift for assembly make me question the reality of their eventual viability as a professional supplier. I guess if it's just a prototype...........
