Product Description: 

The BTS-4000 Series Battery Tester is a versatile, high-precision testing solution designed for both research laboratories and advanced battery development. With models ranging from ultra-low-current 5V10mA/5V20mA/5V50mA units to higher-capacity 5V6A and 5V12A systems, this series supports the full spectrum of battery testing needs. The low-current models are perfectly suited for coin cells, electrode materials, and primary battery evaluation, offering exceptional sensitivity for material screening and electrochemical characterization. The higher-current models feature 8 independent channels and are ideal for testing cylindrical cells (such as 18650/21700) and pouch cells, delivering accurate performance, cycle life, and prototype validation results. Engineered with a 16-bit high-accuracy measurement system, advanced safety protections, and flexible testing modes—including CC, CV, CCCV, CP, pulse, and DCIR—the BTS-4000 Series ensures reliable, repeatable, and professional-grade battery analysis for R&D, quality control, and pilot production environments.
