Rechargeable LiFePO4 battery QOLTEC 10Ah 12.8V 128Wh with integrated BMS

QOLTEC Rechargeable LiFePO4 10Ah 12.8V 128Wh with integrated BMS is a compact lithium iron phosphate battery designed to provide a stable 12.8 V output and reliable 10 Ah capacity. Intended for applications that require safe, long-lasting energy storage, this battery integrates a Battery Management System (BMS) that monitors cell balance and protects against overcharge, overdischarge and short circuit. Its nominal energy of 128 Wh and LiFePO4 chemistry offer improved cycle life and thermal stability compared to conventional lead‑acid batteries.

Advantages

The integrated BMS increases operational safety by managing cell voltages and limiting unsafe conditions. LiFePO4 chemistry ensures a higher number of charge/discharge cycles and more stable voltage under load. The battery’s compact form and moderate weight make it suitable for portable and stationary setups where a 12.8 V supply is required. Low self‑discharge and consistent output voltage contribute to predictable performance in backup and off‑grid systems.

Suitable for

• Backup power for routers, small UPS devices and emergency lighting
• Off‑grid and portable solar systems for small appliances
• Portable electronics and hobby projects requiring 12.8 V supply
• Small renewable installations and energy storage for sensors or controllers

Key specifications

• Battery chemistry: Lithium iron phosphate (LiFePO4)
• Nominal voltage: 12.8 V
• Nominal capacity: 10 Ah
• Nominal energy: 128 Wh
• Integrated protection: Battery Management System (overcharge, overdischarge, short circuit)

How to use

Connect the battery to compatible 12.8 V systems following polarity markings on the terminals. Use a charger or charging device designed for LiFePO4 chemistry and the battery’s nominal voltage to ensure proper charging profile. For multi‑battery setups, follow manufacturer guidance for parallel or series connections; ensure compatible BMS and identical battery types when combining units. Avoid exposing the battery to extreme temperatures and mechanical damage during installation and operation.

Usage recommendations

Use a dedicated LiFePO4 charger with appropriate voltage and current limits. Store the battery partially charged (around 40–60%) if not used for extended periods and keep it in a dry, cool place. Periodically check terminals and connections for corrosion or looseness. Do not attempt to disassemble or modify the integrated BMS.
