    Yes they also use LiFePO4 besides NMC for their ouboards. They also offer a high voltage battery pack made out of current production BMW i3 or i8 modules (wich they specificly mention on the site as assembled in the BMW Dingolfing plant). The 120Ah i3 packs are NMC622, the older 94Ah packs NMC111. Samsung is the cell supplier.
