When connecting batteries in parallel, you add the amp hour ratings of the batteries together, but the voltage remains the same. For example:
The following is the formula for connecting batteries in parallel: P= V*I/Rt where P is the power (in watts), V is the voltage of each battery (in volts), I is the current (in amps), and Rt is the total resistance of all batteries in series (in ohms).
The parallel-connected batteries are capable of delivering more current than the series-connected batteries but the current actually delivered will depend on the applied voltage and load resistance. You understand Ohm's Law, but the "parallel batteries supply more current" statement should really be "parallel batteries CAN supply more current".
In a parallel connection, the voltage across the batteries remains the same when batteries are connected side by side, with their positive terminals connected together and their negative terminals connected together. This results in an increase in the total current.
If you have two 12 volt batteries and want to connect them in parallel, there are a few things you need to know. First, connecting batteries in parallel will not increase the voltage. The voltage will remain at 12 volts. However, connecting batteries in parallel will increase the amperage or amp hours.
In parallel connection, the positive terminal of one battery is connected to the positive terminal of another, and the negative terminal of one battery is connected to the negative terminal of another. This results in a combined battery bank with increased capacity. Advantages of Parallel Battery Configuration: 1.
Batteries Part 2
When a battery cell is open-circuited (i.e. no-load and R L = ∞Ω) and is not supplying current, the voltage across the terminals will be equal to E.When a load resistance, R L is connected across the cells terminals, the cell supplies a current I which causes a voltage drop across internal resistance R INT of the cell. Thus this internal voltage drop means that the batteries or cell''s ...

It does this by discharging the higher battery by drawing a current of up to 0.7A from that battery until both battery voltages are equal. If battery balancing does not have the required effect and the voltage difference becomes larger than 0.2V, the battery unbalance is larger than the battery balance can correct.
