How do you calculate the battery life?

The battery capacity is generally calculated in AH (ampere-hours), and the other is calculated in CELL (unit plate) watts (W).

1..AH (Ampere-Hour) is calculated and defined as 20 hours. For example, a 7AH battery refers to a continuous discharge current of 0.35A for a continuous time of 20 hours.

2. W (W (POWER CONSUMPTION)/CELL (UNIT PLATE)) CALCULATION, THE DEFINITION IS BASED ON 15 MINUTES. FOR EXAMPLE, A 1221W BATTERY IS 12V (6 CELLS), AND EACH CELL CAN SUPPLY 21W FOR 15 MINUTES.

3. The charging time is 10 hours as the standard, and the charging current is 1/10 of the battery capacity, fast charging will reduce the battery life.
