Do's and Don'ts for e-bike battery care. What do you ...

Yes...............all the criterea in the OPs post is backed by science but what we do not always know is how much control is exercised by the BMS in the latest EMTB batteries. For example, preventing discharge below a certain% and not charing to 100%/or preventing further charging when cells get beyond a certain temperature..........then charging again once they have cooled.
We also have no idea what criterea is checked when rating a used battery............quite possibly only that each cell is still operating at a given voltage? A better guide is the range the battery delivers but that is difficult to assess because of all the variables for each ride.

What is known is that lithium cells suffer potential damage when fully charged to 100% and allowed to fully discharge to 0%.......heat being the main reason. Optimum performance of a lithium battery is when it maintains a charge between 30% and 80%.
The only things I would add to the OPs list is to avoid charging to 100% unless a full charge is needed for the next ride. I have a 750w/h battery and only ever charge that to 100% once a month. Most charges are to 85%.

Note that the better EMTB chargers do not charge continuously. They go through cycles of charging often at different rates per cycle and interspersed with cycles of cell balancing.
