Connecting deep-cycle batteries involves linking them in specific ways to achieve the desired voltage or capacity.
Series Connections for Increased Voltage
When you need to increase the voltage of your system, you connect batteries in series. This method involves connecting the positive terminal of one battery to the negative terminal of the next battery in the sequence.
How to Connect in Series
- Connect the plus pole of the first battery to the minus pole of the second battery.
- Continue this connection pattern for all batteries in the series.
- The remaining minus pole of the first battery and the plus pole of the last battery are then connected to the system.
- For example, if you connect two 12V batteries in series, you will have a 24V output.
- If you have four 12V batteries, it will yield 48V when connected in series.
| Battery | Connection to other battery | Connection to system |
|---|---|---|
| First Battery | Plus to minus of the next battery. | Minus to the system |
| Second Battery | Plus to minus of the next battery. | None |
| ... | ... | ... |
| Last Battery | None | Plus to the system |
Important Considerations
- Always ensure that batteries being connected in series have the same voltage and type.
- Use appropriately sized cables and connectors for safety and optimal performance.
- Make sure to follow safety protocols when working with batteries.
