Good point, John. I know many mainstream EV manufacturers protect the longevity of the battery pack by limiting charging to something like 90% of maximum capacity and limit discharge to 10% of capacity. It’s my understanding that lithium batteries, like our old buddies the lead-acid batteries, do not last long (i.e. number of discharge cycles is reduced — I mean the number of times you can discharge and recharge the pack) if charged to max and discharged to zero.
