5. Setup and Installation
5.1 Initial Inspection
Upon receiving your battery, inspect it for any visible damage. Ensure all included components are present. It is recommended to fully charge the battery before initial use.
5.2 Connecting Batteries (Series/Parallel)
The ECO-WORTHY 12.8V 280Ah battery supports flexible expansion up to 4 units in series and 4 units in parallel. Always use appropriate battery cables (not included) for your desired configuration.
- Series Connection: Connect the positive terminal of one battery to the negative terminal of the next. This increases the total voltage (e.g., 4 x 12.8V = 51.2V nominal for a 4-pack).
- Parallel Connection: Connect positive terminals together and negative terminals together. This increases the total capacity (e.g., 4 x 280Ah = 1120Ah for a 4-pack at 12.8V).
- Series-Parallel Connection: Combine both methods to achieve desired voltage and capacity (e.g., 4S4P for a 48V 1120Ah system).
