Features:

Multi-Channel Independent Operation: The 4CH Lithium Battery Capacity Tester supports four independent channels for capacity and internal resistance measurement. Each channel operates separately and does not interfere with the others, making it possible to test multiple batteries simultaneously with distinct settings for precise measurements.



Advanced Charge and Discharge Cycles: This tester supports separate charging and discharging functions, allowing up to 9 cycles in automatic mode. It ensures accurate data collection for battery performance evaluation, enhancing the overall efficiency of testing processes. The system automatically cuts off the charge when fully charged and stops the discharge when conditions are met, thereby protecting the battery from overcharging or over-discharging.



Broad Compatibility: Designed to be compatible with all batteries meeting the 2.5V to 3.5V discharge cut-off voltage and the 2.8V to 4.2V charging voltage requirements, it is particularly suited for flat-top 18650 batteries. However, it does not support lithium iron phosphate batteries, focusing on a specific battery type to offer refined and optimized measurements.



Enhanced Safety and Cooling: Equipped with an active fan cooling system, the tester provides effective thermal management to prevent overheating. The system also includes overheat protection, ensuring the safety and longevity of both the tester and the batteries being tested.



User-Friendly Operation: Featuring an intuitive interface with English and Chinese language options, the tester provides clear status prompts and supports data hold functions. It is powered by a bidirectional Type-C interface, making it easy to charge and operate. The compact size (150 x 103 x 36mm) and lightweight design allow for easy portability and storage, making it a convenient tool for both professional and hobbyist use.
