Yes, it does have the 80% option. Although our original BMS (and battery) have been replaced so maybe the newer BMS is what is giving me that. Ours is also the + model (the mid range of three options). I don't know if they differentiated that way.My 2017 does NOT have the 80% charge option. Are you saying that your 2017 DOES have an 80% option? That would be the first time I've ever heard that
On second thought the owners manual talked about the 80% option so maybe it was there all along.
