A Lipo Battery Guide to Understand Lipo Battery

Max continous Amp draw (A)= Battery capacity (Ah) x Discharge rate (C) For a example, we have a 5100mAh 3 cell Lipo battery with a 10C rating. To find the maximum continuous amp draw, we first convert the 5100mAh to 5.1Ah, and multiply that number by 10C, to give a

Battery Capacity Calculator

 · Battery capacity formula. As you might remember from our article on Ohm's law, the power P of an electrical device is equal to voltage V multiplied by current I:. P = V * I. As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the equation by time:. E = V * I * T. Hopefully, you remember that amp hours are a measure
