Heltec 4–6S Active Balancer

Heltec 4–6S Active Balancer — Capacitance Cell Equalizer for Lithium Battery Banks

The Heltec 4–6S Active Balancer is designed to maintain proper voltage balance across lithium battery cells, helping improve performance, stability, and overall battery lifespan. Using active capacitance balancing technology, it transfers energy between cells to keep voltage levels consistent under load.

Ideal for custom lithium battery banks used in high-output car audio and other high-current applications.

Maintain Stable Voltage Across Your Battery Pack

Voltage imbalance is one of the biggest causes of reduced performance and premature wear in lithium systems. This active balancer continuously monitors and redistributes energy between cells, helping maintain consistent voltage levels and improving overall system reliability.

Its compact design allows for easy integration into custom battery setups.
