【📌Self Pick-up only】Humsienk 48V 300Ah/314Ah Bluetooth LiFePO4 Battery with Active Balancing & LCD Touchscreen

To ensure optimal and safe operation, follow these guidelines :

• Environment: Choose a clean, cool, and well-ventilated area, away from direct sunlight and flammable materials.
• Ambient Temperature: The ideal operating temperature range is between 0°C and 45°C (32°F - 113°F) for charging. Avoid using the battery in extreme temperatures.
• Space: Maintain sufficient clearance around the battery as specified in the manual to ensure proper heat dissipation and access for wiring.
• Wall Strength: Ensure the wall can securely support the weight of the battery.

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.
