4.2 Installation Steps
- Prepare Battery Pack: Ensure your battery pack is assembled correctly with all cells at a similar voltage level before connecting the BMS.
- Connect Balance Wires: Connect the balance wires from each cell string to the corresponding ports on the BMS. Always connect the lowest voltage cell first, then proceed upwards.
- Connect Main Power Cables: Connect the main negative (B-) cable from the battery pack to the B- terminal on the BMS. Connect the main positive (P+) cable from the load/charger to the P+ terminal on the BMS.
- Connect Temperature Sensor: Attach the NTC temperature sensor to a central cell or area within the battery pack to monitor temperature accurately.
- Connect Optional Cables: If using, connect the heating cable, CAN cable, and switch according to your system requirements.
- Verify Connections: Double-check all connections for correctness and security before applying power.
5. Operating Instructions
