The Enyak 85 (non X models) use’s CATL’s LFP battery cells, as such LFP batteries are able to tolerate repeated rapid charging better than lithium-ion NMC, and are less sensitive to being fully charged and discharged daily. Its Also worth noting Tesla recommends charging to 100% all the time, which uses the same CATL LFP cells.
The 85X uses NMC cells from LG Chem and are more prone to degradation especially with frequent fast DC charging to 100%
Its also important with the Enyak and any other EV, is the buffer zone between what is the gross and net battery capacity and that you will never be able to charge to 100% of the true capacity, means the battery will never be charged to dangerous or detromental limits. At the same time AC charging, especially home charging will help in the conditioning of the battery compared to fast DC charging.
