QOLTEC LiFePO4 lithium iron phosphate battery 12.8V 10Ah 128Wh with BMS

QOLTEC LiFePO4 lithium iron phosphate battery 12.8V 10Ah 128Wh with BMS is a compact rechargeable battery designed for stable, long-life low-voltage power. The battery delivers a nominal voltage of 12.8 V and an energy capacity of 128 Wh, using LiFePO4 chemistry for improved cycle life and thermal stability. An integrated Battery Management System (BMS) provides essential cell balancing and protection functions to ensure safe charging, discharging and operation in various environments.

Advantages

The LiFePO4 chemistry offers a longer cycle life and higher thermal stability compared with conventional lead‑acid or other lithium chemistries, reducing total cost of ownership over time. The integrated BMS protects against overcharge, overdischarge and short circuit conditions while performing cell balancing to maintain consistent performance across cells. The battery's compact form factor and relatively low weight make it convenient for portable applications and installations with limited space.

Suitable for

• Small off-grid solar systems and cabin power setups
• Uninterruptible Power Supply (UPS) for low-power equipment
• Portable power packs and field equipment
• Telecom or monitoring devices with 12–13V input requirements
• Hobby and DIY projects requiring rechargeable 12V power

How to use

Install the battery in a dry, ventilated location away from direct heat sources and corrosive environments. Connect to compatible charging equipment designed for LiFePO4 chemistry and respect the recommended charging voltage and current limits. Observe correct polarity when connecting to loads or chargers. For multi-unit configurations or parallel connections, follow the manufacturer's guidance regarding balancing, wiring and BMS compatibility. Regularly inspect terminals and connections for corrosion or looseness and ensure mounting is secure to avoid mechanical stress.

Usage recommendations

To maximize service life, use a charger with LiFePO4 charge profile, avoid deep discharge below recommended cut-off, and store the battery at partial state of charge in cool conditions when not in use for extended periods. Periodic checks of the BMS status and connection integrity help maintain reliable operation.
