12 Volts = 8.333 Amps, this volts to amps calculator helps convert volts and watts to current, using Amps = Watts / Volts formula. The calculator utilizes Ohm’s Law to determine the relationship between voltage (V), current (I), and resistance (R). Where P = 100 watts. The formula for converting volts to amps is derived from Ohm’s Law: Where:
The battery capacity is equal to 2.2 Ah. If you expand the "Other battery parameters" section of this battery capacity calculator, you can compute three other parameters of a battery. C-rate of the battery. C-rate is used to describe how fast a battery charges and discharges. For example, a 1C battery needs one hour at 100 A to load 100 Ah.
let's say you have a 100ah lead-acid battery. 100Ah lead-acid battery has a recommended charge and discharge rate of 5 amps let's say you have a 100ah lithium battery. 100Ah lithium-ion battery has a recommended charge and discharge rate of 50 amps How to convert c-rating to time?
To measure a battery's capacity, use the following methods: Measure the time T it takes to discharge the battery to a certain voltage. Calculate the capacity in amp-hours: Q = I×T. Or: Calculate the capacity in watt-hours: Q = P×T. What is the C rating of a battery? The C rating determines the rate at which the battery discharges.
Even if there is various technologies of batteries the principle of calculation of power, capacity, current and charge and disharge time (according to C-rate) is the same for any kind of battery like lithium, LiPo, Nimh or Lead accumulators. To get the voltage of batteries in series you have to sum the voltage of each cell in the serie.
The global capacity in Wh is the same for 2 batteries in serie or two batteries in parallel but when we speak in Ah or mAh it could be confusing. - 2 batteries of 1000 mAh,1.5 V in series will have a global voltage of 3V and a current of 1000 mA if they are discharged in one hour.
