2. Informazioni sulla sicurezza
Always prioritize safety when working with battery management systems and lithium batteries. Failure to follow safety guidelines can result in serious injury, fire, or damage to property.
- Ensure all connections are correct and secure before applying power. Incorrect wiring can cause irreversible damage to the BMS and battery pack.
- Do not insert the BMS to connect the cable while the battery pack is live. Always disconnect the battery pack before connecting or disconnecting the BMS.
- Use appropriate personal protective equipment (PPE), such as insulated gloves and safety glasses, when handling battery components.
- Evitare di cortocircuitare i terminali della batteria o i collegamenti del BMS.
- Keep the BMS and battery pack away from water, moisture, and extreme temperatures. The BMS features waterproof and dustproof properties, but direct exposure should be avoided.
- Utilizzare solo il volume specificatotage and current ratings for the BMS. Exceeding these limits can lead to damage or failure.
- If any unusual behavior, smoke, or excessive heat is observed, immediately disconnect power and consult a qualified technician.

5. Configurazione e installazione
Proper installation is critical for the safe and effective operation of your DALY Smart BMS. Please follow these steps carefully.
5.1 Wiring the Battery Pack
Before connecting the BMS, ensure your battery pack is properly assembled and the balance wires are prepared. Tools needed include a soldering machine (suggested 662°F/350°C), scissors, double-sided tape, tin wire, and a multimeter.
- Preparare il pacco batteria: Ensure the battery cells are arranged correctly and sampling points are identified.
- Secure the BMS: Use double-sided tape to fix the BMS to the battery pack in a stable position.
- Collegare i cavi di bilanciamento: IMPORTANT: You must disconnect balance wires and the BMS connection port before welding black and red balance wires on the battery pack.
- Posizionamento dei fili: Place each balance wire in its correct position on the battery pack. The black wire (B0) connects to the negative terminal of the battery. Subsequent red wires (B1, B2, etc.) connect to the positive terminals of each cell in series, following the sequence.
- Cut and Strip Wires: Once all wires are in place, cut them to the appropriate length and strip the ends for soldering.
- Connessioni a saldare: Carefully solder each balance wire to its corresponding sampling point on the battery pack.
