Battery capacity has doubled compared to the first versions of the i3 from late 2013 (with 60Ah which equals 21.6 kWh) and increased by approximately 30% (33,2x1.3) compared to the second version unveiled in May 2016 94Ah = 33.2 kWh.


Thanks to Björn showing us how his battery looks. He replaced it with a 94Ah battery in his BMW i3.


"Figured I'd show how easy the battery pack of a 60Ah is to take apart! Too easy! Just got the last module out and everything is really super easy to take apart!
Decided to keep my old 60Ah and part it up (to sell) as I just upgraded with a 94Ah one in our neighboring country Norway." - Björn L

"The Samsung SDI cell in the i3 has a very good track record.  It is rated for 4600 full 0 to 100 charge cycles before end of life (where it drops below 80% capacity).  The battery capacity in the service menu isn't very reliable.  Those numbers have a tendency to fluctuate a lot."- Samuel Tolentino
