Let’s explore all about Batteries in Series vs Parallel configurations: When batteries are connected in series, the positive terminal of one battery is connected to the negative terminal of another battery. The voltage adds up while the capacity (ampere-hours) remains the same. Here’s a summary of the characteristics of batteries in series:
The series current and amp-hour capacity is the same as that of one single battery. For batteries connected together in parallel (+ to +, – to –), the voltage does not change and is the same as for one single battery voltage.
Voltage： Series Connection: Batteries in series result in cumulative voltage, where the total voltage equals the sum of individual battery voltages. For instance, linking three 1.5-volt batteries in series produces a total output of 4.5 volts.
The current is the same as for one battery because the same current (I) flows through all the series combination. Since battery capacity (C) in amp-hours relates to the current (I) in amperes, and which is constant in a series circuit, the total amp-hour (Ah) rating of the series combination is the same as for one single battery.
When batteries are connected in series, the voltages of the individual batteries add up, resulting in a higher overall voltage. For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts. Effects of Series Connections on Current In a series connection, the current remains constant throughout the batteries.
Here’s a summary of the characteristics of batteries in series: Increased Voltage: The total voltage across the series-connected batteries is the sum of the individual battery voltages. This is useful when you need to power devices that require a higher voltage than a single battery can provide.

Thus, an ideal voltage source will always supply a current, (I) equal to I = E÷R (Ohm''s Law) when a resistive load, (R) is connected to its terminals. However, all practical voltage supplies and batteries will have some internal resistance, no matter how small that adversely affects its ability to supply a constant current.
Current： Series Connection: Current remains constant across all batteries in the series—the same current flows through each battery. Parallel Connection: In a similar, each battery contributes to the total current. As a result, the overall current capacity increases with the number of batteries connected in parallel.
