Upon receiving your battery, carefully unpack it and inspect for any visible damage. If damage is found, contact customer support immediately.
4.2 Connecting Batteries (Parallel and Series)
The DATOUBOSS 12V 300Ah LiFePO4 battery supports configurations of up to 4 batteries in parallel and 4 in series (Max. 4P4S). This allows for increased capacity and higher voltage awọn ọna šiše.
- Isopọ ti o jọra: Connect positive terminals to positive terminals and negative terminals to negative terminals to increase total capacity (Ah) while maintaining the same voltage (12V).
- Asopọmọra jara: Connect the positive terminal of one battery to the negative terminal of the next to increase total voltage (V) nígbàtí ó ń pa agbára kan náà mọ́ (Ah).
- Series-Parallel (4P4S): For maximum energy storage, up to 16 batteries can be configured in a 4P4S arrangement, achieving a 51.2V 1200Ah system with 61440Wh of energy.
- Always use appropriate cables and connectors for your chosen configuration.
- Ensure all batteries are at a similar state of charge before connecting them in parallel or series.

5. Isẹ
Once installed and charged, your DATOUBOSS LiFePO4 battery is ready for operation. It offers a 100% depth of discharge, meaning you can use its full rated capacity without significantly impacting its lifespan. Monitor your system's voltage and current to ensure it operates within the battery's specifications.
6. Itọju
DATOUBOSS LiFePO4 batteries require minimal maintenance due to their robust design and integrated BMS. Follow these guidelines for optimal performance and longevity:
- Ayẹwo igbagbogbo: Periodically check battery terminals for corrosion and ensure connections are secure.
- Ninu: Keep the battery surface clean and dry.
- Isakoso iwọn otutu: While the BMS provides temperature protection, avoid operating or storing the battery in extreme temperatures for extended periods. The optimal operating temperature range is generally between -20°C to 60°C for discharge and 0°C to 45°C for charge.
- Ibi ipamọ: If storing the battery for an extended period, ensure it is charged to approximately 50% State of Charge (SoC) and stored in a cool, dry place. The battery has an excellent low self-discharge rate.

The integrated BMS handles most common issues by temporarily shutting down the battery. If the battery is not functioning as expected, refer to the table below. The BMS will automatically reset and resume normal operation once the fault condition is removed.
| Isoro | Owun to le Fa | Ojutu |
|---|---|---|
| Battery not providing power | BMS activated due to overdischarge, overcurrent, or short circuit. | Remove the load, check for short circuits, and recharge the battery. The BMS will reset automatically. |
| Batiri ko ngba agbara | BMS activated due to overcharge or low/high temperature. Incorrect charger. | Ensure charger is compatible and within specified voltage/current. Move battery to an appropriate temperature environment. The BMS will reset automatically. |
| Reduced capacity or performance | Aging battery (unlikely within warranty period), extreme operating conditions. | Ensure operating conditions are within specifications. If issues persist, contact customer support. |
