How To Calculate Amp Draw On A Battery. Refer to Table 0-3 to verify the battery size you need to provide at least the total standby current you have calculated. Basically it is Amp-hours x C rating.
Re-arranging this equation and we find that Q EV. To use the RC LiPo Battery Power Configuration Calculator simply use the drop down boxs to select your battery pack specifications. 20 x 20 mins 60 Mins 1hr AH.
As youll note from the equation above The faster a battery is drained discharged the less overall amperage is available.
Then we take the equivalent amp hours of a battery based in its RC or CCA rating see my article link above and divide it by parasitic amps 24 hours. Check One or Both if They Apply. Additionally it provides you with a step-by-step instruction on how to calculate amp hours and watt-hours so you will be able to. For a given capacity C and a discharge current I the time will be However battery capacity decreases as the rate of discharge increases.
