12V 2A LiFePO4 Charger – CC-CV Algorithm for Optimal Battery Health
If you own a LiFePO4 battery, you know that correct charging is essential to prevent premature degradation. Using the wrong charger can damage your cells in just a few months. This smart charger delivers a precise 14.6V output and automatically stops once the charging cycle is complete, ensuring your battery stays in top condition.
Note: Exclusively compatible with 12V LiFePO4 batteries. Do not use with Li-Ion, LiPo, or lead-acid batteries, as the different termination voltages can cause permanent damage.
Why choose this model? (Key Advantages):
- Calibrated CC-CV Algorithm — Delivers a steady 2A current in the initial phase, then automatically switches to a fixed 14.6V for the final stage, exactly as required by lithium iron phosphate chemistry.
- Active OVP and OCP Protection — Integrated over-voltage and over-current protection intervenes instantly if any anomalies are detected, giving you complete peace of mind.
- Clear Bicolor LED Indicator — Red light indicates charging is in progress; green light confirms the battery is fully charged. No more guesswork.
- Universal Input 100–240V / 50-60Hz — Works seamlessly with standard European and international power outlets without the need for additional adapters.
- Standard 5.5×2.1mm DC Connector — Compatible with most energy storage systems, portable solar panels, and UPS units right out of the box.
Performance and Technical Details
The CC-CV charging principle is the gold standard for LiFePO4 battery chemistry. During the first phase, the current remains fixed at 2A regardless of the charge state. Once the voltage reaches the 14.6V threshold, the charger switches to constant voltage mode, gradually tapering the current to zero. This prevents overcharging and protects your cells from premature wear.
Built-in OVP (Over Voltage Protection) and OCP (Over Current Protection) circuits act in real-time to prevent damage. With added short-circuit and overload protection, you can safely leave the charger connected without constant supervision.

Frequently Asked Questions
Can I use this charger for Li-Ion or lead-acid batteries?
No. The 14.6V termination voltage is specifically designed for LiFePO4 chemistry. Using it on Li-Ion or lead-acid batteries may cause overcharging and irreversible damage.
How long does a full charge take?
Charging time depends on your battery capacity. A fully discharged 10Ah battery will take approximately 5 hours at 2A. This model is ideal for batteries between 6Ah and 30Ah.
Does it shut off automatically when the battery is full?
Yes. The CC-CV algorithm progressively reduces the current as the battery nears 100%, and the LED turns green when the cycle is complete, eliminating the risk of overcharging.
Does it work with standard European power outlets?
Yes. The 100–240V / 50-60Hz input range covers the electrical grids in Ireland, Luxembourg, Malta, and most other countries. Simply plug it directly into your wall socket.
