  • How To Calculate Battery Run Time - Lithium ion Battery ...

    Say, 5AH*3.7V/10 Watts = 1.85 hrs. With 90% Power efficiency for Li-ion/LiPo batteries. Then Discharging Time=Battery Capacity * Battery Volt*0.9 Device Watt. 5Ah*3.7V*0.9/10W = 1.66 hours. Let's explain with more examples: for a 1800mAH 3.7v 18650 battery to power a 3.7V 10W digital device, how to calculate the running time?

  • 18650 Battery Pack Calculator - learn how to calculate the ...

    To Achieve the expected operating voltage ( the 18650 battery pack's voltage). We should connecting the 18650 cells in series to increase the voltage. For example: if you want a 36 volt. We should connect 10pcs 3.7 volt 18650 cell in series. Make sure each cell with same Capacity, internal resistance and self discharge rate is same also.
