Calculate power (Watt)

Potential ?	3.8 V (Volt)
Current ?	167.46 A (Ampere)	A = C/s
Resistance ?	22.69 mΩ (Ohm)	Ω = V / A
Active power ?	636.35 W (Watt)	rate of energy transfer / W = V * A

Calculate energy (KWh/Joule)

After 1 hours of continuous power usage:

Charge (Ah)	167.46 Ah
Energy (kWh)	636.35 Wh
Energy (Joule)	2.29 GJ
Energy (Calorie)	547.14 Mcal

Calculate capacity (mAh/Wh)
