Batteria LiFePO4 QOLTEC 12,8 V 50 Ah (modello 53704) per backup e accumulo di energia

The LiFePO4 battery QOLTEC 12.8V 50Ah (model 53704) is a rechargeable lithium iron phosphate battery that delivers a stable 12.8 V output and rated 50 Ah capacity intended for backup power and energy storage applications. Its chemistry and construction provide a predictable discharge behavior, low self-discharge and a compact form factor suitable for UPS systems, telecom equipment, off‑grid installations and other small to medium energy storage needs.

Advantages

The battery uses LiFePO4 chemistry which offers a long cycle life, enhanced thermal and chemical stability, and a lower risk of thermal runaway compared with other lithium battery types. It provides a consistent voltage profile during discharge and retains capacity over many charge/discharge cycles, enabling reliable runtime estimation. The compact 12.8 V module and moderate 50 Ah capacity make it convenient for replacing lead‑acid batteries while reducing weight and maintenance requirements.

Suitable for

• Uninterruptible power supplies (UPS) for small servers and network equipment
• Backup power for telecom cabinets and monitoring systems
• Off‑grid energy storage for solar or wind micro systems
• Battery banks for RVs, boats, and portable power setups
• Emergency lighting and security systems

Key specifications

• Nominal voltage: 12.8 V
• Rated capacity: 50 Ah
• Battery chemistry: Lithium iron phosphate (LiFePO4)
• Typical use: Rechargeable energy storage for backup and off‑grid systems
• Form factor: Compact sealed module suitable for cabinet installation
• Operating temperature range: typical LiFePO4 operating range suitable for indoor installations (consult device limits)

How to use

Install the battery in a dry, ventilated location and secure it according to the installation space and equipment manufacturer’s instructions. Connect to compatible 12.8 V systems, ensuring correct polarity and using recommended cable sizes and terminal connections. Charge the battery with a charger or charge controller designed for LiFePO4 chemistry and follow the specified charge voltage and current limits to maintain battery life. Avoid deep discharge beyond recommended depth of discharge and monitor state of charge where possible.

Recommendations

For best results, use a dedicated LiFePO4 charger or BMS‑compatible charging system, maintain ambient temperatures within the recommended operating range, and store the battery partially charged if it will not be used for extended periods. Regularly check connections and system settings to ensure reliable backup performance.
