4. Configuració i instal·lació
Proper installation is crucial for the performance and safety of your battery.
4.1 Desembalatge i inspecció
- Carefully remove the battery from its packaging.
- Inspect the battery for any visible damage. If damaged, do not use and contact customer support.
- Verify all accessories are present (e.g., terminal bolts).
4.2 Pautes de connexió
- Single Battery Connection: Connect the positive terminal of the battery to the positive input of your load/inverter and the negative terminal to the negative input.
- Connexió paral·lela (per a una major capacitat):
- Ensure all batteries are at a similar state of charge before connecting in parallel.
- Connect the positive terminals of all batteries together.
- Connect the negative terminals of all batteries together.
- Connect your load/inverter to the main positive and negative busbars.
- The battery supports up to 4 parallel connections (4P).
- Connexió en sèrie (per a un volum augmentat)tage):
- Ensure all batteries are at a similar state of charge before connecting in series.
- Connect the positive terminal of the first battery to the negative terminal of the second battery, and so on.
- The remaining free positive terminal of the first battery and the free negative terminal of the last battery will be your system's output.
- The battery supports up to 4 series connections (4S).
- Combined Series-Parallel Connection (4P4S): For maximum capacity and voltage, up to 16 batteries can be configured in a 4P4S arrangement. Consult a qualified electrician for complex setups.

7. Solució De Problemes
If you encounter issues with your DATOUBOSS LiFePO4 battery, refer to the following common problems and solutions:
| Problema | Causa possible | Solució |
|---|---|---|
| La bateria no es carrega | Loose connections, faulty charger, BMS protection activated (over-discharge) | Check all connections. Ensure charger is compatible and functioning. If BMS is in protection mode, try to wake it up with a compatible charger or by applying a small load. |
| Sense potència de sortida | Battery discharged, BMS protection activated (over-discharge, short circuit), loose connections | Check battery charge level. Verify all connections are secure. If BMS is in protection mode, address the cause (e.g., remove short circuit, charge battery). |
| Sobreescalfament de la bateria | Overload, poor ventilation, high ambient temperature | Reduce load. Ensure adequate ventilation around the battery. Move battery to a cooler environment if possible. The BMS will trigger thermal protection if temperatures are too high. |
| Reduced capacity/runtime | Aging battery, improper charging, extreme operating conditions | Ensure proper charging cycles. Avoid frequent deep discharges to 0%. While the battery has a long lifespan, gradual capacity reduction is normal over many years of use. |
