Store the battery between 20% and 80% for long periods. A battery left at 100% in a hot garage loses capacity faster than one stored cool at half charge.
Avoid charging immediately after a cold ride. Let the pack come to room temperature, especially below freezing.
Use the charger that came with the bike. Cheap chargers are the most common cause of the connector and BMS failures we see.
If the bike will sit for the winter, charge to about 60%, disconnect the battery, and check it once a month.
