DSF20 is integrated with the function of a high-precision capacity series discharging test and high-precision series charging test. With a wide voltage testing range from 9V to 99V which make it can test varieties of batteries from 12V-84V. Charging test and discharge test can be performed for lead-acid batteries, lithium batteries and other types of batteries. The maximum charge & discharge cycle index is 16 times, which can also be used as the aging equipment in the battery production.

The device provides two operation modes: Panel and Software. After installing the specified software, the device can be managed and operated through the computer: charge-discharge setting, data sampling, test report import and export, test data analysis, charge-discharge curves drawing. One computer can manage multiple devices simultaneously through a switch.  

It is a high-precision specific instrument suitable for electric vehicle & battery manufacturers and its dealers to test the performance of battery pack. And it can be widely used in battery testing and maintenance, production, sales and after-sales service，lab battery R & D as an efficient & intelligent battery testing and maintenance equipment.
