Qoltec Voltage balancer for 24V batteries 2 x 12V | 5A | LiFePO4 AGM GEL | LED

Qoltec Voltage balancer for 24V batteries 2 x 12V | 5A | LiFePO4 AGM GEL | LED

Product code: 51078

The Qoltec 24V voltage balancer is a practical device for balancing the voltage between two 12V batteries in 24V systems. It automatically transfers current from the more fully charged battery to the less charged one, which prevents uneven wear. This increases the efficiency of the entire system and extends the service life of the batteries. Ideal for use in electric cars, solar installations, boats and forklift trucks.

Smart protection for your 24V installation - stability you can rely on

Reliable compact device to support long and trouble-free operation of 12V battery packs

Automatically compensates for differences in battery voltage, protects against damage and increases battery life ensuring stable and safe operation of 24V installations – All this in a compact, fireproof housing, ready to work in any conditions. Does not require connection to 230V mains, operates fully autonomously drawing power from connected batteries. Ideal for demanding and long-lasting applications from photovoltaics to electric vehicles.

Balance tension, gain efficiency

Recommended battery capacity 20Ah - 200Ah
Powered directly from batteries - no 230V AC mains connection required
• High-precision integrated circuits reduce component deviation
Clear dual LCD display – full control over the balancer’s operation

Real-time monitoring of the voltage of both batteries

The voltage balancer is fitted with a dual, easy-to-read display which shows the current voltage of each of the two 12V batteries operating in a 24V system. This allows the user to easily monitor the condition of the set and quickly spot any voltage differences between the batteries. The displayed values make it easier to assess the device’s operation and allow you to check whether the voltage equalisation process is proceeding correctly.

Quick and safe installation

How to connect a voltage balancer

Before connecting the voltage equalizer Make sure that both batteries are fully charged, have the same type and identical capacity. The voltage difference between them should not exceed 0.2V. It is also extremely important that the batteries are properly connected in series, and the total voltage of the system is about 24V. Connecting the balancer is simple - just connect the black wire to the minus, red to the plus of the entire 24V set, and white to the point between the batteries – The rest will be taken care of by the balancer. The device will start automatically and LEDs A and B will let you know that the system is working and taking care of your batteries.

Works with any 24V system - Universal application, wide compatibility

For camper, yacht, photovoltaic - Compatible with AGM, GEL, LiFePO4, NCM and LTO batteries

The 24V voltage balancer is an excellent choice wherever you use two 12V batteries connected in series. Ideal for campers, caravans, boats, solar systems, electric vehicles, forklifts and emergency power systems. No problem works with lead-acid batteries (AGM, GEL), as well as with lithium batteries, such as LiFePO4, NCM or LTO. This small device can significantly extend the life of the entire battery and prevent costly failures.
