4. Nastavitev in namestitev
4.1 Razpakiranje in pregled
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 sistemi.
- Vzporedna povezava: Connect positive terminals to positive terminals and negative terminals to negative terminals to increase total capacity (Ah) while maintaining the same voltage (12 V).
- Serijska povezava: Pozitivni pol ene baterije priključite na negativni pol naslednje, da povečate skupno glasnost.tage (V) ob ohranjanju enake kapacitete (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. Delovanje
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. Vzdrževanje
DATOUBOSS LiFePO4 batteries require minimal maintenance due to their robust design and integrated BMS. Follow these guidelines for optimal performance and longevity:
- Redni pregled: Občasno preverjajte, ali so priključki akumulatorja korodirani, in se prepričajte, da so povezave trdne.
- Čiščenje: Površina baterije naj bo čista in suha.
- Upravljanje temperature: 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.
- Shranjevanje: 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.
