LG Energy Solution E78 Battery Module – 44V, 156Ah, 6.85kWh
Genuine LG Energy Solution E78 battery module as fitted to the Volkswagen Group MEB platform (ID.3, ID.4, ID. Buzz, Skoda Enyaq, Audi Q4 e-tron and others). Manufactured at LG's Wroclaw facility in Poland, these are current-generation, automotive-grade NMC modules offering outstanding energy density, proven reliability and full transport certification.
Each module contains 24 LG E78 pouch cells in a 12S2P configuration, delivering 156Ah at a nominal 44.04V for 6.85kWh of energy in a compact, fully enclosed aluminium housing. The robust cast end frames incorporate mounting points and threaded terminal blocks, making the module straightforward to integrate into series strings for EV conversions, marine propulsion and stationary energy storage.
