3. Configuració

3.1 Desembalatge i inspecció

• Carefully remove the battery from its packaging.
• Inspect the battery for any visible damage, such as cracks, dents, or loose terminals. If damage is found, do not use the battery and contact customer support.
• Verify that all included accessories (if any) are present.

3.2 Càrrega inicial

It is recommended to fully charge the battery before its first use to ensure optimal performance and calibrate the BMS. Use a compatible LiFePO4 charger.

3.3 Connexions de terminals

• Assegureu-vos que totes les connexions estiguin netes, ajustades i sense corrosió.
• Connecteu el terminal positiu (+) de la bateria al terminal positiu (+) del vostre carregador/carregador.
• Connecteu el terminal negatiu (-) de la bateria al terminal negatiu (-) de la vostra càrrega/carregador.
• Use appropriate gauge cables for your application to prevent overheating.

3.4 Series and Parallel Connections

The KUNLUN 12V 100Ah LiFePO4 battery supports connecting up to 16 units in series and/or parallel to achieve higher voltage or capacity. Ensure all batteries are of the same model and state of charge before connecting.

3.4.1 Series Connection (for higher voltage)

• Connect the positive terminal of one battery to the negative terminal of the next battery.
• El vol totaltage will be the sum of individual battery voltages (e.g., four 12.8V batteries in series yield 51.2V).
• The total capacity (Ah) remains the same as a single battery.

3.4.2 Parallel Connection (for higher capacity)

• Connect all positive terminals together and all negative terminals together.
• The total capacity (Ah) will be the sum of individual battery capacities (e.g., four 100Ah batteries in parallel yield 400Ah).
• El vol totaltage remains the same as a single battery.

4. Instruccions de funcionament

4.1 mètodes de càrrega

The KUNLUN LiFePO4 battery can be charged using various methods. It is recommended to choose only one charging method at a time.

Imatge 4.1: acabatview of three common charging methods: Solar Panel with Charge Controller, dedicated Battery Charger, and Generator with LiFePO4 Charger.

• Panell solar: Connect to a compatible solar charge controller designed for LiFePO4 batteries.
• Carregador de bateria: Use a dedicated LiFePO4 battery charger. Ensure the charger's voltage and current settings are appropriate for a 12V 100Ah LiFePO4 battery.
• Generador: Connect a LiFePO4 charger to a generator for charging.

4.2 Protecció de càrrega a baixa temperatura

The built-in BMS includes low-temperature charging protection. Charging will automatically cut off when the battery temperature is below 0°C (32°F) and will resume when the temperature rises above 5°C (41°F). The battery can safely discharge down to -20°C (-4°F).

4.3 Aplicacions

The KUNLUN 12V 100Ah LiFePO4 battery is suitable for a wide range of deep cycle applications:

• Vehicles recreatius (RV)
• Sistemes d'emmagatzematge d'energia solar
• Marine Applications (Trolling Motors)
• Camping and Outdoor Power
• Sistemes d'alimentació de seguretat

5. Manteniment

Proper maintenance ensures the longevity and optimal performance of your KUNLUN LiFePO4 battery.

• Inspecció periòdica: Periodically check the battery terminals for corrosion or loose connections. Clean terminals with a wire brush if necessary and ensure they are tightened securely.
• Neteja: Keep the battery casing clean and dry. Use a damp cloth to wipe off dust or dirt. Do not use harsh chemicals or solvents.
• Emmagatzematge: If storing the battery for an extended period, ensure it is charged to approximately 50-70% State of Charge (SOC). Store in a cool, dry place, away from direct sunlight and extreme temperatures. Disconnect the battery from all loads and chargers during storage.
• Eviteu la descàrrega profunda: While the BMS protects against over-discharge, consistently operating the battery at very low states of charge can reduce its overall lifespan.

6. Solució De Problemes

This section addresses common issues you might encounter with your KUNLUN LiFePO4 battery.

6.1 La bateria no es carrega

• Comproveu les connexions: Ensure all charging cables are securely connected to the battery and charger.
• Compatibilitat amb el carregador: Verify that you are using a LiFePO4 compatible charger with the correct voltage i sortida de corrent.
• Temperatura: If the ambient temperature is below 0°C (32°F), the BMS will prevent charging. Move the battery to a warmer environment (above 5°C / 41°F) for charging to resume.
• Protecció BMS: The BMS may have triggered an over-discharge protection if the battery was deeply discharged. Some chargers have a 'wake-up' function for such cases. Consult your charger's manual or contact support.

6.2 Battery Not Providing Power

• Comproveu les connexions: Ensure all load connections are secure and free of corrosion.
• Estat de càrrega de la bateria: The battery may be fully discharged, triggering the BMS over-discharge protection. Recharge the battery.
• Sobrecàrrega/curtcircuit: The BMS may have activated over-current or short-circuit protection. Disconnect the load, inspect for faults, and reconnect. The BMS should reset automatically once the fault is cleared.
• Temperatura: If the battery is operating outside its safe discharge temperature range (-20°C to 50°C), the BMS may temporarily shut down.

6.3 Reduced Capacity or Runtime

• Incomplete Charging: Assegureu-vos que la bateria s'està carregant completament.
• Envelliment: While LiFePO4 batteries have a long cycle life (5000+ cycles), capacity will gradually decrease over many years of use.
• Alta taxa de descàrrega: Very high continuous discharge rates can temporarily reduce usable capacity.
