Humsienk 48V Wall-Mounted LiFePO4 Battery for Home Storage & Off-grid Backup

These 48V batteries are designed to work with inverters rated for 48V battery banks.

Connecting communication cables (like RS485, CAN, or RS232) between the battery and a compatible inverter allows for "closed-loop" communication. This enables the inverter to receive real-time data from the Battery Management System (BMS) for more precise charging and optimal performance.

• Avoid Extreme Temperatures: High heat accelerates degradation, and charging at temperatures below 0°C (32°F) can cause permanent damage unless the battery has a built-in self-heating function .
• Use a Compatible Charger: Always use a charger or inverter with charging profiles specifically designed for LiFePO4 batteries.
• Optimal Storage: If storing the battery for a long period, charge it to 40%-60% state of charge and keep it in a cool, dry place. Check and recharge it every 3-6 months.
• Regular Use: Periodic full charge/discharge cycles can help the BMS calibrate the state of charge reading for better accuracy.

Most wall-mounted batteries support parallel connection to increase total capacity (e.g., from 5kWh to 15kWh). When paralleling, always use batteries of the same brand, model, and age. Use cables of the same length and gauge for each battery to ensure balanced charging/discharging. Adhere to the manufacturer's limit on the maximum number of parallel units.
