## Summary description

QOLTEC LiFePO4 rechargeable battery, 12.8V nominal voltage, 7Ah capacity (89.6Wh) with an integrated Battery Management System (BMS). Designed for reliable low-voltage power in portable devices, backup systems, lighting, telecom or small off-grid applications. The BMS provides cell balancing and protection against overcharge, overdischarge and short circuit for safer operation and longer service life.

## Long description

QOLTEC rechargeable LiFePO4 battery with a nominal voltage of 12.8V and a usable capacity of 7Ah (89.6Wh) is designed to provide stable low-voltage power for portable devices, small backup systems, lighting and telecom equipment. The cell chemistry offers a balance of cycle life and safety, while the integrated Battery Management System (BMS) manages cell balancing and basic protections to ensure reliable performance during charge and discharge cycles.
Advantages
The LiFePO4 chemistry provides improved cycle life and thermal stability compared to many other lead-acid or lithium chemistries. Built-in BMS delivers protection against overcharge, overdischarge and short circuit, and performs passive cell balancing to prolong usable life. The compact 12.8V form factor is compatible with systems that expect a 12V nominal supply while offering higher usable energy density and lighter weight than equivalent lead-acid batteries.
Suitable for
 Portable power banks and field equipment that require a compact 12.8V source
 Small uninterruptible power supplies (UPS) and backup modules for network devices
 Low-power off-grid systems and lighting for cabins, signage or security
 Telecommunications equipment and monitoring devices with low to moderate current draw
Key specifications
 Chemistry: Lithium Iron Phosphate (LiFePO4)
 Nominal voltage: 12.8 V
 Rated capacity: 7 Ah (89.6 Wh)
 Integrated Battery Management System providing cell balancing, overcharge, overdischarge and short-circuit protection
 Typical operating temperature range suitable for indoor and sheltered outdoor installations
 Compact rectangular form factor for easy mounting in small enclosures
How to use
Install the battery in a dry, well-ventilated location and secure it to prevent movement. Connect positive and negative terminals to the corresponding system inputs, observing correct polarity. Charge the battery using a charger compatible with LiFePO4 chemistry and a charging voltage appropriate for a 12.8V nominal battery; avoid chargers designed only for lead-acid batteries. The integrated BMS will manage cell balancing and protective cutoffs during normal operation. Follow system manufacturer guidelines for wiring, fusing and current limits.
Usage recommendations
For longest service life, store and operate the battery within recommended temperature ranges, avoid deep discharges when possible, and use a LiFePO4-compatible charger. Regular inspections of terminals and connections are advised. When integrating into backup or telecom systems, include appropriate fusing and protection on output lines and follow local safety standards.
