5. Enstalasyon ak Enstalasyon

Proper installation is crucial for the safe and efficient operation of your BMS. Follow these steps carefully:

5.1 Chèk Pre-Enstalasyon

• Ensure your battery pack matches the BMS specifications (4S-8S, Li-ion/LiFePO4/LTO).
• Verify all battery cells are balanced and within a healthy voltage range before connecting the BMS.
• Rasanble tout zouti ak eleman ki nesesè yo.

5.2 Koneksyon fil elektrik

Enpòtan: Connect the balance wires first, then the main power cables. Disconnect in reverse order.

1. Balance Wire Connection: Konekte s laampling cable to each cell's positive terminal, starting from B- (0V) up to B+ (total voltage). Ensure the sequence is correct.
2. B- Connection: Connect the main negative terminal of the battery pack to the B- port on the BMS.
3. P- Connection: Connect the negative terminal of your load/charger to the P- port on the BMS.
4. B+ Connection: Connect the main positive terminal of the battery pack to the B+ port on the BMS.
5. Pò kominikasyon: Connect RS485, CAN, or UART cables as required for external communication or monitoring.
6. Capteur NTC: Attach the NTC temperature sensor to a central cell or area within the battery pack to monitor temperature.
