4.2. Instruccions de cablejat
- Identificar terminals: Identify the total positive terminal (B+) and total negative terminal (B-) of your battery pack.
- Connect B- Wire: Connect the first black cable and the blue B- wire to the total negative terminal of the battery pack. Securely tighten.
- Connecta Sampling Cables: Connect the rest of the sampling cables to the individual cell terminals in sequential order (B0, B1, B2, etc.). Ensure each cable is connected to the correct cell.
- Insulate Excess Wires: If using fewer series than the BMS supports, do not short-circuit the excess wires. Securely tape them up with insulation tape to prevent accidental contact.
- Verificar Sampling Cables: Use a multimeter to check the sampling cable connections.
- Place the black probe on B0.
- Place the red probe on B1, B2, B3, and so on.
- The multimeter should display positive voltage readings, and the voltages should increase step by step. If this is observed, the wiring is correct.
- Precaució: During testing, do not let the two probes touch each other, as this may cause a cable short circuit.
- Connect BMS B- Terminal: Connect the B- wire from the battery pack to the B- terminal on the BMS.
- Insert NTC Sensor: Insert the temperature sensor (NTC) cable into the NTC port on the BMS.
- Plug in Sampling Cable: Carefully plug the main sampling cable connector into the corresponding port on the BMS.
- Connect B+ Wire: Connect the B+ wire from the battery pack to the B+ terminal on the BMS.
- Verify BMS Operation: If the green light on the BMS is on, the BMS is working properly.

7. Solució De Problemes
This section addresses common issues you might encounter with your DALY Smart Active Balance BMS.
| Problema | Causa possible | Solució |
|---|---|---|
| "Cell Level 1 Overvoltage Alarm" | Cèl·lula de bateria voltage és massa alta. | Start using (discharging) the battery to reduce cell voltage. Check charging parameters. |
| No WiFi connectivity | WiFi dongle not connected or configured correctly. WiFi is for cloud connectivity, not local. | Ensure the BT+WiFi dongle is correctly connected via UART. For local connectivity, use Bluetooth. Verify WiFi module is properly installed and configured for cloud access. |
| LCD screen plug incompatible | Incorrect LCD screen model or adapter for the specific BMS version. | Ensure you have the correct LCD screen and adapter compatible with your DALY BMS model. Consult the product specifications or seller for compatible accessories. |
| BMS not turning on (no green light) | Incorrect wiring, especially B- or B+ connections, or sampling cable issues. | Double-check all wiring according to the diagrams (Figures 4 & 5). Verify sampling cable voltages with a multimeter. Ensure B- and B+ are securely connected. |
| Excess sampling wires | Using a BMS with more series capacity than the battery pack. | Securely tape up any unused sampling wires with insulation tape. Do NOT short-circuit them. |
