Thank you very much for sharing!
I was almost sure it would work but I wasn't sure about how many parts needed to be changed.

What's next a 40kWh? :mrgreen:

Excellent, well done! That looked seriously cold.

Is this a way to swap any battery without Nissan's Consult tool? VCM + LBC + key programming? I hope so.

What year of Leaf did you upgrade jsa0161, I have a 2012 I would like to do this too but I am not sure what I would have to do with the extra connector from the 30 kwh battery for the heater.

It was cold, very cold! :D

I was offered help from a person who owned this tool: this tool:https://www.aliexpress.com/item/OBDSTAR-X-100-ProS-OBD2-Auto-Key-programmer-C-model-eeprom-security-code-reader-same-x200/32687310187.html
He had used it to register keys with the Leaf in the past and also thought it would be possible to register my key with VCM, using this tool.
Unfortunately he lived to far away so never got a chance to take him up on his offer. I think it would have worked.

I got a 2014 Leaf. There could be other issues with a 2012 model. Not sure if the 30 kwh VCM would have worked. Yes, no? I don't know.

I don't think the extra connector for the battery heater would have been a deal breaker though. Probably just a can bus error code, but I'm guessing the car would still have worked.

They changed the canbus-with-friends-connector on the first gen1 battery back to the second gen ( 2013 +) so you need a adapter for that.

Just removed my deffective 30kwh from my leaf and replaced with a 24kwh battery. So yeah a downgrade.
12 bars restored , only one small issue
Error code " p3102 invalid battery".
The battery needs pairing with the vehicle, unfortunately nearest dealership refused to do it because they not HV battery trained.

I have VCM from donor car so looking to replace that.
The vehicle drives in limited mode now. Once i take off the VCM will be immobilized...

So you could try the HV pairing tool from evsenhanced, however, that tool only is certified to work with like for like replacements. Nissan doesn't officially support replacing a 30 kWh battery with anything other than a 30 kWh battery and the tool hasn't been tested doing that. I have no idea if it would work for your situation.

I can say the tool works well. I just used it to swap a 12 bar 24kWh battery into my 7 bar 2011.

I sounds like someone has already succeeded in changing battery capacity by swapping the VCM's as well as the battery. You could do that at the dealership, then have them program the keys, assuming they're willing to.

I swapped a 2011 warranty replaced battery into another 2011 car. The mounting brackets and rear cover plates were different but the cabling itself was the same.

Because I had both cars (and not just the battery), all the parts were available to swap.

I have sent them a message and waiting for reply.

Dealer accepted to relearn my keys if i replace the VCM on my own... will be only next week to find out if will work or not.
