AFAIK, the 77 kWh and 79 kWh packs have the same number of modules, and they're the same size too. VW still make and sell both too, which makes you wonder why the 79 exists. The larger pack/new modules are mostly used in the higher power models (IE, the GTX models), so it's possible they just have better discharge performance. I guess there's a chance that might also lead to better cycle life if they're a little more robust too, but time will tell on that.Was pretty sure the theme of the discussion was a ID3 and 58 vs 77 battery. The key discussion point being the 77 appears to degrade less
The 77 has recently changed to 79 for most of the MEB range but with fewer but larger cells. Probably a factor in the peak going to 185kW. (And needed for more current to the 210kW motor) One up in the buzz is 86 then can do 200kW. More cells. More charge on that extra module
