Parallel Connection (Max 8 units)

1. Place all batteries as required.
2. Install the CAN impedance matching connector on the last battery in the chain.
3. Connect communication cables between all batteries.
4. Trigger the system to assign IDs: Select the master battery and press the Key button for at least 5 seconds until the LED blinks.
5. Wait for the system to complete the setup (all LEDs flash 3 times).
6. Connect the positive/negative parallel wires to the P+/P- terminals.

Series Connection (Max 3 units)

1. Ensure all batteries are fully charged to 100% SOC before connecting.
2. Install the CAN impedance matching connector on the last battery.
3. Connect communication cables.
4. Trigger the system to assign IDs (press Key button for 5 seconds).
5. Connect the positive/negative series harness.

Battery Operation

The battery features a Key button and LED indicators for SOC (State of Charge) and working status. Pressing the Key button triggers all batteries to display their SOC. Master and Slave batteries are identified by their blinking patterns during normal operation.

Maintenance and Disposal

• Storage: Store in a dry, well-ventilated area (15-25°C). If stored for long periods, keep at 60% SOC and discharge/recharge every 3 months.
• Temperature: Do not charge, discharge, or heat the battery if the temperature is at or below -20°C.
• Disposal: Do not place in ordinary garbage. Dispose of via a specialized battery recycling company.

Troubleshooting

If a protection alert is triggered, disconnect the battery and wait before restarting.

• Key button does not trigger LED: Charge the battery immediately (over-discharge).
