5. Configurazione e installazione
5.1 Attivazione iniziale
After first receiving the battery or if it has been switched off for an extended period, you need to activate it. Charge the battery using a lithium-activation charger or an MPPT charger to activate the Bluetooth function and ensure full functionality.
5.2 Collegamento terminale
Connect your devices to the M8 terminals using the provided bolts and insulating caps. Ensure connections are secure to prevent arcing or overheating. If using thin OT terminals (less than 2mm thick), use appropriate gaskets to ensure a tight and safe connection.
5.3 Collegamenti in serie e in parallelo
This battery supports connecting up to 16 batteries in a 4-series, 4-parallel (4P4S) configuration. This allows for creating systems up to 48V 200Ah, providing 10240Wh of energy and a maximum load power of 10240W. When connecting batteries in series or parallel, ensure all batteries are of the same voltage and capacity, and follow proper wiring diagrams to maintain balance and safety.
6. Istruzioni per l'uso
The LiTime 12V 50Ah LiFePO4 battery is ideal for powering trolling motors with 12V thrust up to 20-70 lbs, fish finders, and other marine or RV electronics.
- Tasso di scarico: The maximum continuous discharge current is 1C (50A). It can sustain a maximum 1.2C (60A) continuous discharge for up to 30 minutes. Ensure your load does not exceed these limits.
- Funzionamento a bassa temperatura: The battery features low-temperature protection. Charging will automatically stop below 0°C/32°F and resume above 5°C/41°F. Discharging will stop below -20°C/-4°F.

8. Linee guida per la ricarica
Proper charging is crucial for the lifespan of your LiFePO4 battery. Always use a charger specifically designed for LiFePO4 batteries.
- Caricabatterie consigliati: LiFePO4 battery chargers, MPPT solar charge controllers (for solar systems), generators (AC to DC chargers), and alternators (DC to DC chargers).
- Tasso di carica:
- 0.2C (10A): Approximately 5 hours
- 0.5C (25A): Approximately 2 hours (Recommended)
- 1C (50A): Approximately 1 hour
- Ricarica a bassa temperatura: The BMS will automatically prevent charging when the internal battery temperature is below 0°C (32°F) to protect the cells. Charging will resume once the temperature rises above 5°C (41°F).
