The batteries on the 60 & 80 series are made by CATL. The batteries on the 85 series are made by LG Chemicals. http://www.catl.com http://www.lgchem.com The BMS (Battery Management System) is upgraded on the 85x & VRS models.
VW groups 82kWh (77kWh net) use LG Chem’s LGX E78 Cells. Each cell has a capacity of 78Ah and an energy density of 265 Wh/kg. The cell chemistry is NCM 712.
Each of the VW groups 55kWh, 60kWh, 80kWh, batteries contain a varying number modules containing 24 LGX E78 cells, in a battery pack configuration as below..

Skoda confirmed 85, 85x and VRS retain the same 77kWh unit as the 80 and 80x. A boost in range and power, is provided as a result of changes to the battery and energy management software, and an upgraded AP550 motor. This is also confirmed for the rest of the VW as a whole.
VW group builds its own battery packs in Europe using imported LG Chem cells. Skoda’s Mladá Boleslav plant is the only European production facility for MEB battery systems outside Germany. Battery systems from Mladá Boleslav used in ŠKODA, Volkswagen, Audi and SEAT MEB models.
VW Group MEB platform cars are supplied with CATL’s 590 large module, ultra thin 57kWh and 87kWh battery’s, to FAW-VW and SAIC VW in China. They use NCM811 cells and have an energy density of 270Wh/kg prismatic format and 300 Wh/kg in pouch format.
