Batteries are like women, good treatment is more durable do not deep discharge do not leave them on the charger forever no frost and no heat. If you notice that the battery does not like it any more, help it a little. Touch it from time to time and feel the temperature. The built-in BMS will kill the battery if the cell is faulty, one is enough.

My battery was new and the scooter burnt out. It didn't last 5 months. So not recommended for such a price.

Have had the scooter for 2 years. Battery is full. Can no longer start it. Does anyone know the problem?
