Heltec Energy Battery Active Balancer – 2~24S Fast Automatic Equalizer

Key Features:

Supports 2–24 series lithium batteries, including ternary lithium (NCM), lithium iron phosphate (LFP), and lithium titanate (LTO), with voltages between 2V and 4.5V.

Automatic detection of the lowest voltage string for efficient balancing.

Overvoltage (4.5V), low-voltage (2V), and reverse connection alarms for enhanced safety.

Automatic stop and alarm notification upon balance completion.

Real-time display of individual cell voltage, total voltage, voltage differences, and balance status.

No charging during balancing, preventing the risk of overcharging.

Battery Maintenance Process:

Identify faulty battery cells and replace if necessary.

Fully charge the battery pack before balancing.

Start the balancing process to ensure all cells reach uniform voltage.

Fully charge again after balancing to optimize battery performance.

Battery maintenance complete for improved efficiency and lifespan.

Discharge Balancing System:

Constant 1-ohm discharge resistance for stable operation.

Energy discharge balancing ensures faster and even balancing across all battery strings.

No risk of overcharging, as the system only discharges excess energy from high-voltage cells.

Package Includes:

16AWG silicone wire (blue) with alligator clips – sold separately.

This balancer provides fast, precise, and automatic battery equalization, ensuring extended battery life, improved performance, and safe operation.
