Will the battery 18650 battery capacity AH is how to count?
Learned physics friends know, W (watts, power units) = V (volts, voltage units) × A (safety, current units).
18650 battery capacity of 3.7V × 2200mAh = 8.14Wh, which know the three-core battery capacity 8.14 × 3 = 24.42Wh, four-cell battery capacity 8.14 × 4 = 32.56Wh, six-cell battery capacity of 8.14 × 6 = 48.84Wh.
And the data is exactly equal to the product of the battery tag. To six core, for example, 48.84Wh = 11.1V × 4400mAh.
