Correct! The 120 Ah battery pack is only 40 kg. heavier than the 60 Ah battery pack.Also: there are examples of the 60ah battery having been upgraded to the 94ah one for the first generation ones. Weight didn’t increase significantly.
Several European and Chinese mechanics seem to have figured out how to upgrade i3 battery packs without problems, apparently even including higher capacity battery cells that were never installed in i3's by BMW. Whether U.S. i3 owners will ever benefit from these upgrades remains uncertain.Software and coding were the biggest challenges and I don’t know whether that can ever be reverse engineered; I certainly don’t expect BMW to ever open source it. Even with what sounds like a simple upgrade from 60 to 94ah there were complications with getting the car to “understand and accept” the larger module.
