5.2 Series and Parallel Connection
The battery supports a maximum 2S4P connection for flexible capacity expansion. Always ensure all batteries are at a similar state of charge before connecting them in series or parallel.
This video provides a step-by-step guide on how to connect two 24V 200Ah batteries in series to achieve a 48V 200Ah system, and in parallel to achieve a 24V 400Ah system. It demonstrates the use of power cables and an Anderson connector power cable for secure connections.
5.2.1 Series Connection (e.g., for 48V 200Ah)
- Connect the positive terminal of one battery to the negative terminal of the other battery using a power cable.
- Attach the Anderson connector power cable to the remaining open positive and negative terminals.
- Verify the voltage with a multimeter to ensure the connection is correct (e.g., approximately 48V for two 24V batteries).
5.2.2 Parallel Connection (e.g., for 24V 400Ah)
- Connect the positive terminals of both batteries to each other using a power cable.
- Connect the negative terminals of both batteries to each other using another power cable.
- Attach the Anderson connector power cable to one of the positive and one of the negative terminals.
- Verify the voltage with a multimeter to ensure the connection is correct (e.g., approximately 24V for two 24V batteries).
Always use appropriate cables and connectors for your application to prevent overheating and ensure safe operation.
