Informació de seguretat
Your DATOUBOSS LiFePO4 battery is equipped with a built-in 100A Battery Management System (BMS) to ensure safe operation and protect against common issues. Please adhere to the following safety guidelines:
- Protecció BMS: The integrated BMS protects against high temperature, over-voltage, overload, overcharge, over-discharge, overcurrent, and short circuits.
- Interval de temperatura: The battery is designed for continuous discharge operation from -4°F to 150°F (-20°C to 65°C). Ensure operation within these limits.
- Terminal Handling: Avoid short-circuiting the positive and negative terminals. Always use appropriate tools and ensure secure connections.
- Instal·lació: Ensure proper ventilation around the battery. Do not install in sealed compartments where gases can accumulate.
- Càrrega: Use only chargers compatible with LiFePO4 batteries. Standard lead-acid chargers may not fully charge the battery or could damage it.
- Danys físics: Do not modify, disassemble, or throw the battery into fire or water. Avoid dropping or subjecting the battery to severe physical shock.

Key specifications like 12.8V 100Ah capacity, 1280Wh storage, 50A max charging current, and 120A max discharge current are also shown.
2. Battery Pack Expansion (Series/Parallel)
The DATOUBOSS 12V 100Ah LiFePO4 Battery supports both series and parallel connections for increased voltage or capacity. It can be expanded up to 4P4S (4 parallel, 4 series) to create a 48V (51.2V) 400Ah Li-Ion battery pack, delivering up to 20.48kWh of energy. Always ensure all batteries in a series or parallel bank are of the same voltage, capacity, and brand. Consult a professional for complex configurations.

Image: A diagram illustrates how multiple 12.8V 100Ah batteries can be connected in series (4S) to increase voltage to 48V (51.2V) while maintaining 100Ah capacity, or in parallel (4P) to increase capacity to 400Ah while maintaining 12V. Both configurations result in 5120Wh of energy.
Funcionament de la bateria
1. Alimentació de dispositius
Connect your 12V devices directly to the battery terminals using appropriate wiring and fuses, or connect the battery to an inverter for AC power. Ensure the inverter's input voltage matches the battery's output voltage.
Video: A seller demonstrates connecting a 12V 100Ah LiFePO4 battery to a soft wash pump system. The video shows the battery being placed into a battery box, and then the pump's power switch being turned on, indicating successful operation.
2. Carregant la bateria
The battery can be charged using a compatible LiFePO4 charger, solar panels with an MPPT controller, or a generator. The charging voltage should be 14.4V ± 0.2V. The maximum charge current is 100A.

An inverter is connected to the battery system to power various household loads, demonstrating a maximum 20.48kW load power.
3. Temperature Considerations
The battery is designed to operate effectively in extreme temperature variations. It can continuously discharge from -4°F to 150°F (-20°C to 65°C). For optimal lifespan, avoid prolonged exposure to temperatures outside the recommended operating range.

A temperature gauge indicates its ability to operate from -4°F (low temperature) to 150°F (high temperature), emphasizing its resilience to extreme temperature variations.
Manteniment
- Regularly inspect battery terminals for corrosion or loose connections. Clean and tighten as needed.
- Store the battery in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods.
- For long-term storage, ensure the battery is charged to approximately 50% state of charge.
Resolució de problemes
If the battery is not functioning as expected, check the following:
- Sense potència de sortida: Verify that the battery terminals are securely connected and that the BMS has not triggered a protection mode (e.g., due to over-discharge or short circuit).
- Problemes de càrrega: Ensure your charger is compatible with LiFePO4 batteries and is providing the correct voltage (14.4V ± 0.2V). Check for proper connection between the charger and the battery.
- Sobretemperatura: If the battery feels excessively hot, disconnect all loads and charging sources immediately. Allow the battery to cool down before resuming operation.
