It is a good thing to understand how to connect your batteries in different configurations; the two main configurations being in series and in parallel. This is an easy task and you don’t need any special skills or tools in order to connect your batteries.
Connecting Batteries in Parallel – Same Voltage / Higher Capacity:
Connecting two or more batteries in parallel will increase the capacity of the batteries, without changing the voltage output. This configuration is widely used in scooters, UPS backups, laptops and other applications.
In order to connect your batteries in parallel simply connect the positive terminal of the first battery to the positive terminal of the second battery with a wire. Then connect the negative terminals in the same way. Now that two the batteries are connected you can simply run two wires from the positive and negative terminal of one of the batteries.
Connecting Batteries in Series – Higher Voltage / Same Capacity:
Connecting two or more batteries in series will increase the voltage without changing the capacity rating. This configuration is widely used in kids’ toy cars, scooters and other similar applications.
In order to connect your batteries in series simply connect the negative terminal of the first battery to the positive terminal of the second battery with a wire. You can now connect your application to the two remaining terminals, positive to positive and negative to negative.
Some General Tips
- Check the requirements of your application before connecting your batteries
- Don’t connect different batteries
- Don’t connect batteries with different capacities
- Use heavy duty wire when connecting batteries in parallel
