Rechargeable LiFePO4 Battery QOLTEC 12.8V 30Ah 384Wh with BMS

QOLTEC 12.8V 30Ah LiFePO4 rechargeable battery provides a stable 12.8 V nominal output and 384 Wh of usable energy in a compact, lightweight package. The cell chemistry and integrated Battery Management System (BMS) deliver long cycle life, consistent voltage under load and built-in protections against common fault conditions. The battery is designed for applications that require reliable DC power, reduced maintenance compared with lead‑acid batteries, and improved energy density for mobile or stationary backup systems.

Advantages

The LiFePO4 chemistry offers a longer service life and higher cycle stability than traditional lead‑acid batteries while maintaining thermal and chemical stability. An integrated BMS handles cell balancing and provides protection against overcharge, overdischarge and short circuits, helping to preserve battery health and safety. The battery’s nominal 12.8 V output and 30 Ah capacity deliver predictable performance for a wide range of devices, with lower self‑discharge and lighter weight compared with equivalent lead‑acid options.

Suitable for

• Uninterruptible Power Supplies (UPS) for small to medium systems
• Off‑grid and grid‑tied solar storage for residential or portable installations
• Mobile power for RVs, boats and field equipment
• Backup power for telecom equipment, monitoring systems and emergency lighting

Key specifications

• Nominal voltage: 12.8 V
• Nominal capacity: 30 Ah
• Rated energy: 384 Wh
• Cell chemistry: LiFePO4 (lithium iron phosphate)
• Integrated Battery Management System: cell balancing, overcharge, overdischarge and short‑circuit protection
• Typical applications: UPS, solar energy storage, mobile power and backup systems
• Physical attributes: compact and lighter than comparable lead‑acid batteries (exact dimensions and weight depend on manufacturer specification)

How to use

Install the battery according to the system manufacturer’s instructions, ensuring correct polarity and secure connections. Charge with a charger or charge controller compatible with LiFePO4 batteries and configured to the appropriate charge voltage and cut‑off thresholds for 12.8 V nominal chemistry. For parallel or series configurations, follow guidelines for matched capacity and state‑of‑charge to avoid imbalance; the integrated BMS aids protection but does not replace correct installation practices. Regularly check terminals for tightness and signs of corrosion and keep the battery in a dry, ventilated environment within the recommended temperature range.

Usage recommendations

For optimal longevity, operate the battery within recommended charge and discharge limits, avoid deep discharges where possible, and use a proper LiFePO4 charge profile. Store the battery at partial state‑of‑charge (around 40–60%) if it will be unused for extended periods. Use compatible chargers and follow safety procedures when connecting multiple batteries or integrating with inverters and charge controllers.
