Qoltec 48V batterij-balancer voor 4 x 12V batterijen | 10A | AGM GEL LiFePO4 | LED

Unlike passive balancers that waste excess energy as heat, the Qoltec 51079 actively transfers charge between batteries, ensuring each 12V unit in your 48V bank stays perfectly balanced. This 10A active balancer works with AGM, GEL, flooded lead-acid, and LiFePO4 batteries, making it a versatile choice for solar installations, RVs, off-grid cabins, and UPS systems.

Highlights

• Active balancing technology with 10A maximum equalization current
• Compatible with 4 x 12V batteries in series (48V system)
• Supports AGM, GEL, flooded lead-acid, and LiFePO4 chemistries
• LED indicators for power and balancing status
• Wall-mountable ABS housing with screw terminals
• Efficiency over 95% with ultra-low self-consumption (<10mA)

In daily use

Installation is straightforward: connect the balancer to each battery's terminals using the screw terminals, and the device automatically begins monitoring and equalizing voltages. The LED indicators provide clear feedback, while the reverse polarity and low voltage disconnect protections prevent damage. Operating from -20°C to +55°C and up to 90% non-condensing humidity, it's built for demanding environments.
