Hi all,
Did a battery upgrade on a BMW i3 REX, it went from 60AH to 120AH (42.2kWh). I still have to do some coding to get it out of power restricted mode, but really nice to see that these upgrades are possible, and almost plug'n'play!


I'll make a longer video with more details once I get the coding done!

To follow up on this topic, I made a video which explains all the pitfalls of the 120Ah upgrade. Thanks again to Havrla!

Excellent presentation, thank you for pointing out the difficulties to be aware.
Thanks! Glad you liked it, I hope this will inspire more shops/competent DIYers to try this upgrade, and find better solutions for the tricky parts!

Dala, is there a company or shop in California that is able to do the i3 120 battery upgrade?
