In addition to the BMW 5 Series (G30) 530e the same battery pack can be found in the 7 Series (G12) 740e. These battery packs consist of six battery modules yielding 351 volts. The same battery modules can be found in the 3 Series (F30) 330e but in a smaller form factor made up of only five modules and 293 volts.
First Gen (-2018)
The SP06 has a capacity of 26 Ah.
Second Gen (2019-present)
The SP41 high-voltage battery was installed in the G30 Plug-in Hybrid Electric Vehicle starting in July of 2019. It has the same basic design as the SP06. The most significant change is the cell capacity increase from 26 Ah to 34 Ah.
