The Lead-Acid & Lithium Battery Series Charge Discharge Tester DSF20 is integrated with the function of a high-precision capacity series discharging test and a high-precision series charging test. With a wide voltage detection range from 9V to 99V which make it can measure 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 battery production.

The device provides two operation modes for the convenience of customers, Panel operation and Online operation. 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 the battery pack. And it can be widely used in battery testing and maintenance, production, sales, and after-sales service as efficient & intelligent battery testing and maintenance equipment.

Applicable Batteries:
Lithium battery packs, lead-acid batteries


- Instrument displays by LCD, each index is clear at a glance.
- The parameter setup and parameter switching are set and switched by a “START” switch and a “SET” knob. All parameters (voltage, current, mode) settings have the saving function.
- Intelligent speed fan can run continuously, delay the power-off of the fan, and blow off the remaining heat.
- Polarity protection, anti-reverse connection, and so on.
- Each circuit is the independent module, no influence each other
Maximum cycle number is 99, which can be used as battery aging equipment.
- Data protection startup: If the connection cables disconnected from the battery during the charging and discharging, after reconnecting the cables with the battery, press and hold the “Start” button to continue working.
- Power-off memory function.
Modular design, easy maintenance and replacement of accessories. 
- Two operation methods: Panel & Software. After installing the specified software, the device can be managed and operated through the computer: charge-discharge setting, data sampling, test report imports and exports, test data analysis, charge-discharge curves drawing.
- One computer can manage multiple devices simultaneously through a switch, make testing more efficient and simpler.
