## Summary description

Qoltec 48V battery voltage balancer designed for systems with four 12V batteries, supporting AGM, GEL, and LiFePO4 types with a 10A equalization current. Features LED status indicators for real-time monitoring. This device maintains equal charge levels across all connected batteries, preventing overcharging and premature degradation, which extends overall battery bank lifespan in solar systems, electric vehicles, and backup power setups.

## Long description

The Qoltec 48V Battery Voltage Balancer is an essential device designed to maintain equal charge levels across four connected 12V batteries in a 48V system. By continuously monitoring and balancing the voltage, this unit prevents overcharging, sulfation, and premature degradation of individual cells. It supports multiple battery chemistries including AGM, GEL, and LiFePO4, offering a versatile solution for energy storage systems. Equipped with a 10A equalization current and practical LED status indicators, it ensures reliable and efficient operation for demanding power setups.
Advantages
Using a dedicated battery voltage balancer significantly improves the overall performance and longevity of a battery bank. Uneven charging often occurs in series-connected systems due to minor differences in internal resistance and capacity, which can lead to early failure of the entire bank. This device actively redistributes energy to weaker batteries during charging and discharging cycles, ensuring that every unit operates within safe voltage limits. The integrated LED indicators provide instant visual feedback on the operational status, allowing for quick checks without the need for multimeters. Its broad compatibility with popular battery technologies like AGM, GEL, and LiFePO4 makes it adaptable to various existing and new installations.
Suitable for
Solar energy storage systems using 48V battery banks
Backup power supplies and uninterruptible power supply setups
Electric vehicles and mobility carts utilizing multiple 12V batteries
Off-grid power installations in remote locations or cabins
Marine power systems with 48V configuration
When it may not be suitable
This device is specifically designed for 48V systems utilizing four 12V batteries connected in series. It is not suitable for systems with a different voltage rating, such as 12V, 24V, or configurations with a different number of individual units. Additionally, it cannot be used with battery types other than AGM, GEL, and LiFePO4.
Key specifications
Designed for 48V battery systems
Compatible with four 12V batteries
Supports AGM, GEL, and LiFePO4 battery types
Maximum equalization current of 10A
Equipped with LED status indicators
How to use
Installation of the battery voltage balancer requires careful connection to the battery bank according to the wiring diagram provided in the user manual. Each of the four 12V batteries must be connected to the corresponding terminal lines of the balancer to ensure proper voltage distribution. Once correctly wired, the device operates automatically, continuously monitoring the voltage differences between the units and adjusting the current as needed. Regular visual inspection of the LED indicators is recommended to verify normal operation and ensure that all batteries remain balanced.
What to consider before purchase
Verify that your existing battery setup consists of exactly four 12V batteries connected in a 48V configuration
Check that your battery chemistry is either AGM, GEL, or LiFePO4
Ensure the 10A equalization current matches the requirements of your battery capacity
Confirm available physical space for mounting the balancer near the battery bank
For optimal performance and safety, install the voltage balancer as close to the battery bank as possible using appropriate wire gauges, and periodically check all terminal connections for security and signs of wear.
