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.
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.
Battery A has a voltage of 6 volts and a current of 2 amps, while Battery B also has a voltage of 6 volts and a current of 2 amps. When connected in series, the total voltage would be 12 volts, and the total current would remain at 2 amps. Advantages and Disadvantages of Series Connections
When wiring two batteries in series, follow these steps for safe installation: Two identical batteries (same type, voltage, and capacity). Appropriate connectors (ensure they can handle higher voltages). Tools for securing connections (e.g., wrenches). Connect the positive terminal of Battery 1 to the negative terminal of Battery 2.
When batteries are connected in parallel, the voltage across each battery remains the same. For instance, if two 6-volt batteries are connected in parallel, the total voltage across the batteries would still be 6 volts. Effects of Parallel Connections on Current
Using our 12 volt battery from the previous example, four batteries (or cells) are connected in series (represented as one voltage source and one series resistance) so the voltages add up (4 x 12V = 48V). The current is the same as for one battery because the same current (I) flows through all the series combination.
