3. Istruzioni di sicurezza
- Always wear appropriate personal protective equipment (PPE) when handling batteries and BMS units.
- Ensure all connections are correct and secure before applying power. Incorrect wiring can cause damage to the BMS, battery, or connected devices, and poses a fire risk.
- Non cortocircuitare i terminali della batteria o l'uscita del BMS.
- Keep the BMS away from water, moisture, and flammable materials unless specifically designed for such environments (this model is waterproof, but general caution is advised).
- Non tentare di aprire o riparare l'unità BMS. Per l'assistenza, rivolgersi a personale qualificato.
- Verify battery cell voltage polarità prima di effettuare il collegamento al BMS.

5. Configurazione e installazione
Proper wiring is crucial for the correct function and safety of the BMS and battery pack. Follow these steps carefully.
- Step 1: Soldering Wires
Connect the first wire (black wire) to the total negative terminal of the battery (B-). Connect the second wire (red wire) to the first series battery positive terminal. Continue connecting subsequent red wires to each successive series battery positive terminal until all balance wires are connected. - Step 2: Test the Wires
After connecting the balance wires, measure the voltage between two adjacent wires from the header. Ensure that the voltage readings are consistent with individual cell voltages, confirming that the wires are not connected in the wrong order. - Step 3: Connect Output Wires and Activate
Connect the B- wire of the protection board to the total negative terminal of the battery. Then, plug the sampling row wires (balance wires) into the protection board. After activating the protection board, confirm that the voltage before the board (battery voltage B+ to B-) and the voltage after the board (P+ to P-) are the same.
Figura 5.1: Detailed wiring diagram for DALY BMS installation. This diagram illustrates the connections for the sampling line (balance wires), B- (main negative), and P- (load negative), showing how the BMS integrates with the battery pack and external loads/chargers.
Nota: The NTC (Negative Temperature Coefficient) thermistor is integrated into G series models. Ensure it is positioned correctly to monitor battery temperature.
6. Istruzioni per l'uso
Once properly installed, the DALY BMS operates automatically to manage and protect your battery pack.
- Ricarica: Connect your compatible battery charger to the P+ and P- terminals (or designated charge terminals if separate). The BMS will monitor cell voltages and temperatures, initiating passive balancing as needed and terminating charging if overvoltage or overcurrent conditions are detected.
- Scaricamento: Connect your load to the P+ and P- terminals. The BMS will monitor discharge current, cell voltages, and temperature, disconnecting the load if overcurrent, undervoltage, or over-temperature conditions occur.
- Bilanciamento: The BMS features passive equalization to help maintain cell voltage consistency during charging. This function activates when cells reach a certain voltage soglia.
7. Manutenzione
- Controllare regolarmente tutti i collegamenti elettrici per verificarne la tenuta e la corrosione.
- Mantenere l'unità BMS pulita e libera da polvere e detriti.
- While the unit is waterproof, avoid prolonged submersion or exposure to harsh chemicals.
- Monitor battery pack performance. Any significant deviation in capacity or voltage dovrebbe essere indagato.
8. Risoluzione Dei Problemi
If you encounter issues with your DALY BMS, consider the following:
- BMS not activating / No output voltage:
- Check all wiring connections, especially the balance wires and main power connections (B- and P-).
- Assicurarsi che il pacco batteria sia caricotage rientra nell'intervallo operativo.
- Verify that the balance wires are connected in the correct sequence and that no wires are swapped.
- If the BMS has a separate activation switch or procedure, ensure it has been followed.
- Battery not charging / Discharging:
- Controllare il sovravoltage o undervoltage protection activation. Measure individual cell voltages.
- Verify charger and load connections.
- Check for overcurrent protection activation. Reduce load or charging current.
- Inspect the NTC temperature sensor for proper placement and connection.
- Cellule sbilanciate:
- Ensure the BMS has sufficient time to balance cells during charging. Passive balancing is a slow process.
- Verify that the balance wires are correctly connected to each cell.
- If cell imbalance persists, individual cell testing may be required.
