Dual Output Range TestersCT-4000

Dual range significantly improved the accuracy of Neware BTS4000 series batter testers, and more importantly, it made CVD(constant voltage discharge) function come into reality. Meanwhile, it also helps customers to save cost. Currently there are 5V10mA/50mA/6A/12A available, more models on the way.
