Why choose it

The Qoltec 52672 combines high current output with a power-factor-corrected design, reducing wasted energy and lowering running costs. Its three-stage algorithm protects LiFePO4 chemistry from overcharging, while the built-in safeguards prevent damage from common wiring mistakes. The fan-cooled aluminum chassis ensures reliable operation even in warm service environments.

Ideal use cases

• Charging large LiFePO4 house banks in RVs, boats, and off-grid solar installations
• Bench charging of 12V LiFePO4 batteries in repair shops and battery testing labs
• Maintaining standby LiFePO4 batteries in telecom and security systems
• Fast recharging of deep-cycle LiFePO4 batteries in industrial equipment

Good to know

This charger is designed specifically for LiFePO4 chemistry and should not be used with lead-acid or other lithium-ion batteries. The alligator clips provide a secure connection for temporary charging, and the LED indicators show charging status and any fault conditions. Always ensure proper ventilation during operation.
