Can I use the same formula for different battery types? While the basic formula for kWh remains consistent (kWh = Voltage x Current x Time), the specific methods for calculating kWh may vary for different battery types. Lead-acid and lithium-ion batteries, for example, have distinct characteristics that require specific approaches.
The energy in Joules (in watt seconds), is calculated using the following formula; The charge in the battery is calculated using the formula; Where; Qbatt is the charge in the battery in Coulombs (C), Cbatt is the rated Ah of the battery. The total terminal battery bank voltage is calculated using the formula;
To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
The current flowing between the batteries during this process will be quite high: it is equal to the different between the 2 voltages divided by the sum of the internal resistances of the batteries: I = (V1 − V2)/(R1 + R2) I = (V 1 − V 2) / (R 1 + R 2) This current may damage one or both of the batteries.
Consider the example of two batteries connected in parallel: Battery A has a voltage of 6 volts and a current of 2 amps, while Battery B has a voltage of 6 volts and a current of 3 amps. When connected in parallel, the total voltage remains at 6 volts, but the total current increases to 5 amps. Advantages and Disadvantages of Parallel Connections
Current total = the sum of current capacities of all the individual rungs (each battery on a rung must have the same current capacity). The example shown in Figure 3 presents 24 V to a load and can provide a current of up to 2 A. Figure 3: This series-parallel battery configuration shows 24 V to the load and can provide up to 2 A of current.
So, the circuit diagram for the two batteries in parallel must include the internal resistances which will give consistent results. The bottom line is that one of the batteries will supply power to the other and it is possible that one or both batteries will be damaged and, possibly, violently so.

By symmetry, the current through each cell is the same at 20/12 = 1.66A per cell. There would be no current through the lateral connections (assuming all cells are matched). The current through each of the lengthwise connections would be the same and each would contribute half of the current.
Current total = the sum of current capacities of all the individual rungs (each battery on a rung must have the same current capacity). The example shown in Figure 3 presents 24 V to a load and can provide a current of up to 2 A.
It is simply the time t needed to fully charge or discharge the battery when using the discharge current, measured in minutes. You can calculate it as t = 1/C. What is the capacity of a battery?
