5. Setup: Installation and Wiring
Careful installation and wiring are crucial for the proper function and safety of your BMS. Follow these steps precisely:
Image 3: Detailed wiring diagram for the DALY Smart BMS 4S 12V 400A.
- Solder Sampling Cables: The first black cable in the sampling cable set connects to the negative terminal of the battery (B-). The second cable (red) connects to the positive terminal of the first string of batteries. Continue this pattern for all subsequent strings until all cables are connected to their respective positive terminals.
- Кабелдерди текшерүү: After connecting the sampling cables, use a multimeter to measure the voltage between two adjacent cables starting from the header. Ensure there are no incorrect connections or missing connections.
- Чыгаруу зымдарын туташтырыңыз: Connect the B- wire of the BMS to the total negative terminal of the battery pack. Then, plug the sampling cable into the BMS. After activating the BMS, confirm that the voltage (батарея томtage) between B+ and B- and the voltage between P+ and P- are consistent.
Important: The BMS will not activate until a charge is applied to the battery pack through the BMS. Ensure your cells are pre-charged for storage before connecting.
