Akun jännitteentasaaja QOLTEC 51097 24V (2×12V) akuille, 5A tasausvirta

QOLTEC 51097 is a voltage balancer engineered for 24V battery banks composed of two 12V batteries. The device provides a continuous 5A balancing current to equalize the state of charge between the two battery blocks, reducing the risk of one battery becoming overcharged or undercharged. Designed for use in backup power systems, solar installations and vehicle electrical systems, the balancer helps maintain stable voltage distribution and supports longer battery service life through passive active balancing during charge and discharge cycles.

Advantages

The balancer offers a straightforward electrical solution to common imbalance issues in 24V (2×12V) configurations by redirecting excess charge from the higher-voltage battery to the lower-voltage one at up to 5A. Installation requires minimal wiring and does not need complex configuration, making it compatible with typical lead-acid and AGM 12V batteries used in backup and mobile applications. The device operates automatically once connected and provides continuous protection against state-of-charge divergence that can shorten overall battery pack performance.

Suitable for

• 24V battery banks assembled from two 12V lead-acid or AGM batteries
• Uninterruptible power supply (UPS) backup systems
• Small-scale solar power systems with 24V battery storage
• Recreational vehicles, boats and mobile power applications using 2×12V batteries

Key specifications

• Nominal system voltage: 24V (configured as two 12V batteries)
• Balancing current: 5 A continuous
• Operating mode: automatic passive/active balancing during charge and discharge
• Connection: direct wiring to each 12V battery terminal
• Compatibility: compatible with common 12V lead-acid and AGM battery types

How to use

Mount the balancer in a dry, ventilated location near the battery bank and connect its leads to the positive and negative terminals of each 12V battery following the wiring diagram supplied with the unit. Ensure all battery terminals are clean and tight before connection. After wiring, the device begins balancing automatically; no further configuration is required. Periodically inspect the connections and battery condition as part of routine maintenance to ensure continued correct operation.

Recommendations

Use the balancer only with matched 12V batteries installed in series to form a 24V bank. Avoid connecting the device to individual 12V batteries that are not part of a 24V series assembly. For optimal results, integrate the balancer into systems with regular charge sources and protect batteries from deep discharge and extreme temperatures.
