Qoltec 24V balancer μπαταρίας για 2 x 12V μπαταρίες | 5A | AGM GEL LiFePO4 | LED

Unlike basic voltage equalizers that only trickle a few milliamps, the Qoltec 51078 actively transfers up to 5A between two series-connected 12V batteries, keeping your 24V bank perfectly balanced and dramatically extending its service life. It works with AGM, GEL, flooded lead-acid, and LiFePO4 chemistries, making it a universal solution for solar storage, marine, RV, and off-grid systems.

Highlights

• Active balancing current of 5A for fast equalization
• Supports AGM, GEL, flooded lead-acid, and LiFePO4 batteries
• LED status indicator for quick visual confirmation
• Wide operating temperature range from -20°C to +55°C
• Protection against reverse polarity, short circuit, over-voltage, and under-voltage
• Screw terminal connections for secure wiring
• Compact ABS housing for easy surface mounting

In daily use

Install the balancer across two 12V batteries wired in series for 24V. It begins balancing when either battery exceeds 13.5V and stops at 14.4V, preventing overcharge. If one battery drops below 10V, the unit disconnects to protect the bank. With self-consumption under 3mA, it won't drain your batteries when idle. The LED confirms active balancing at a glance.
