The EKCH004 tester is designed to efficiently test lithium battery cells' capacity through advanced equipment comprising a computer interface and a battery detection cabinet. Each device supports testing of 256 batteries independently within specified voltage ranges, ensuring precise charge and discharge cycles.

Key features include a patented constant current-constant voltage power supply for smooth transitions, AVR single-chip computer control, real-time voltage detection, power failure protection, and software for parameter configuration and data analysis. It accommodates batteries such as lithium iron phosphate with dedicated components to meet specific discharge voltage requirements.
