Why Choose Active Balancing?

Energy Transfer Active Balancing

Transfers energy from high-voltage cells to low-voltage cells

Passive Balancing

Dissipates excess energy from high-voltage cells via resistors

High energy utilization, low heat generation High balancing current, quickly eliminates cell inconsistencies, shortens charging time Effectively improves battery pack capacity utilization and service life

No energy recycling, low energy utilization Generates significant heat during balancing The equalization current is usually small,
difficult to handle large cell capacity differences

Innovative Active Balancing Function

Adopts high-efficiency dynamic energy control algorithm Equipped with high-precision differential ADC chip

High-speed energy transfer, millisecond-level cell voltage difference detection, extremely low heat generation Maximum weighted balancing current up to 3A

Performance Comparison

Balancing completed in ~15 minutes 2300% efficiency improvement Over previous generations (which took 6 hours) Data accurate to 3 decimal places

Experimental conditions: Indoor temperature 25℃, 2200mAh/3S battery, maximum voltage difference per cell 100mV (Data provided by ISDT Labs)

Previous Generation: Balancing takes up to 6 hours Data displayed to only 2 decimal places

Multi-Platform APP Control

Beyond on-screen control, enable remote connection to break distance limits for battery balancing management, all at your fingertips

Supports Windows, MacOS, iOS, Android, HarmonyOS, Linux and other mainstream platforms

Wide-View Angle Color Screen

Clear display from any angle

Vibrant visibility day and night

One-Key Control, Worry-Free Balancing

Smart screen lock design: screen stays bright during balancing, auto-sleeps when idle for power saving and peace of mind
