We do not know the size of the battery. I'm going to have to go back to the 4680 thread to refresh what we were told about them. I'm interested in performance degradation related to battery charge. I know my current P seems to noticeably drop in performance as charge drops, it would be nice if the Plaid could keep (rated) performance numbers up for longer as the battery drops. I am firmly in the larger the battery pack the better camp.
