5. Installation

5.1. Installation physique

1. Montage: Place the battery in a secure, well-ventilated location, away from direct sunlight, heat sources, and flammable materials. Ensure the battery is stable and cannot move during operation.
2. Relations: Connect the positive (+) terminal of the battery to the positive terminal of your load/charger and the negative (-) terminal to the negative terminal. Use the provided M8 terminals and ensure all connections are tight and secure to prevent arcing or overheating.
3. Series/Parallel Configuration: The Dyness 12.8V 100Ah Bluetooth battery can be expanded up to 4 series and 4 parallel (4S4P) for a maximum of 16 batteries, forming a 51.2V 400Ah power system. Follow proper wiring diagrams for series and parallel connections to avoid damage.

5.2. Configuration de l'application Bluetooth

The Dyness battery features Bluetooth 5.0 for real-time monitoring via the "Dyness" app. Ensure you are within 10 meters of the battery for optimal connection.

1. Téléchargez l'application : Rechercher "Dyness" in your smartphone's app store (iOS or Android) and install it.
2. Connexion à la batterie : Open the app. You may need to create an account or select "Local Connection" under the "Services" section. The app will scan for nearby Bluetooth devices.
3. Choisir un appareil: Once your battery (e.g., AR1.2-MINI BT) appears, select it to connect. You can then view données en temps réel.

6. Mode d'emploi

6.1. Chargement

For optimal battery health and safety, use a LiFePO4-specific charger. Recommended charging rate is 0.2C (20A for a 100Ah battery).

• Connect the LiFePO4 charger to the battery terminals.
• Monitor the charging process via the Dyness app.
• The built-in BMS will automatically manage over-charging protection.

6.2. Décharge

The battery is designed to handle high discharge currents, especially for applications like trolling motors.

• For currents exceeding 120A, the BMS will cut off after 60 seconds.
• For currents exceeding 200A, the BMS will cut off after 10 seconds.
• For currents exceeding 300A, the BMS will cut off after 5 seconds.
• For currents exceeding 500A, the BMS will cut off after 1 second.

6.3. Protection contre les basses températures

The battery features an intelligent low-temperature protection system:

• Charging automatically disconnects when the battery temperature drops below 0°C (32°F).
• Charging resumes when the temperature rises to 5°C (41°F).
• Power automatically cuts off at -20°C (-4°F) to prevent cell damage during extreme cold.

7. Entretien

• Inspection régulière : Vérifiez régulièrement l'état des bornes de la batterie (corrosion, connexions desserrées). Nettoyez-les si nécessaire.
• Stockage: Si vous stockez la batterie pendant une période prolongée, assurez-vous qu'elle soit chargée à environ 50 % de son niveau de charge (SOC) et entreposez-la dans un endroit frais et sec. Évitez les températures extrêmes.
• Nettoyage: Keep the battery surface clean and dry. Use a damp cloth to wipe off any dust or dirt. Do not use harsh chemicals.
• Évitez les décharges profondes : While LiFePO4 batteries tolerate deep discharge, it is generally recommended to avoid consistently discharging below 20% SOC to maximize lifespan.

8. Dépannage

8.1. La batterie ne se charge pas

• Vérifier les connexions : Ensure all charging cables are securely connected to the battery and charger.
• Compatibilité du chargeur : Verify that you are using a LiFePO4-specific charger. Lead-acid chargers may not fully charge or may damage the battery.
• Température: If the ambient temperature is below 0°C (32°F), the low-temperature protection may prevent charging. Move the battery to a warmer environment.
• Protection du système de gestion technique du bâtiment (GTB) : The BMS might have activated due to over-discharge, over-voltage, or over-current. Check the Dyness app for alarm status.
