Core Features & Advantages

Efficient Intelligent Cooling System

Equipped with a dual-sided high-performance cooling system: three high-speed fans with bilateral airflow channels, paired with dual heat sinks, rapidly reduce the device’s operating temperature during long-duration tests. This prevents overheating, ensures stable performance, and improves test efficiency, all housed in a durable metallic casing.

Comprehensive Safety Protection

Anti-reverse connection protection: Automatically triggers protection when positive/negative terminals are reversed, eliminating short-circuit risks and device damage, greatly enhancing test safety.

Multi-layer protection against overvoltage, overcurrent, and over-temperature, minimizing risks to both the tester and the battery under complex testing conditions.

Intuitive User Interface

A high-precision LCD display provides real-time monitoring of critical data: voltage, current, charge-discharge capacity, running time, cycle count, cut-off voltage, and more. The clear, user-friendly interface is complemented by physical START/PAUSE and SET buttons for easy operation, supporting seamless switching between multiple test modes.

Flexible Testing Capabilities

Supports charge-discharge cycle testing, capacity calibration, aging performance testing, and more. Users can customize charge/discharge parameters, cut-off conditions, and cycle counts to meet diverse testing requirements for battery R&D, production quality control, and after-sales maintenance.

Interface & Structural Design

Front Panel: LCD display, START button, SET knob, OUTPUT port, and power switch for clear, convenient operation.

Rear Panel: Power socket, LAN port, and status indicator light, enabling data transmission and remote monitoring for production lines and laboratory data logging.
