4.4 Fast Charging
The SM15 battery has added fast charging, which is performance to charge battery faster than the
SM10 LTE battery charging function.
When you use fast charging function, you can keep it faster as much as about half an hour.
By using a PCM(Protection Circuit Module) in each cell, more current is used, which improves
charging times and eliminates risk of battery explosion due to overcurrent. So, you can experience
faster charging time than before.
