Description
The DSF20 Lead-Acid & Lithium Battery Series Charge-Discharge Tester is a high-precision, professional-grade diagnostic and aging instrument designed for comprehensive battery pack evaluation. Integrated with both high-precision series charging and series discharging capabilities, it features a wide voltage detection range from 9V to 99V, making it fully compatible with 12V through 84V battery packs across lead-acid (Pb-acid), lithium-ion, and various other chemistries.
Equipped for both standalone panel control and advanced PC software management via a LAN/TCP-IP connection, the DSF20 supports multi-device networking, automated data sampling, real-time charge-discharge curve plotting, and Excel report export. With a maximum cycle index of up to 99 cycles, robust hardware safety protections, and independent modular architecture, it serves as an essential tool for battery manufacturers, EV dealers, and maintenance workshops.
Note: Product design or firmware versions may vary slightly based on manufacturing batches. AC power cord, communication cables, and test leads are included as per standard manufacturer packaging.
Key Features
- Wide 9V–99V Voltage Range: Supports comprehensive charge and discharge testing for 12V, 24V, 36V, 48V, 60V, 72V, and 84V battery packs.
- Dual Operation Modes (Panel & Software): Manage tests locally via the LCD display and intuitive SET/START controls, or remotely via PC software over a LAN network.
- Multi-Device PC Management: Connect multiple testers to a single computer through a network switch for centralized data logging, curve drawing, and report generation.
- Automatic Cycling & Aging: Supports up to 99 charge-discharge cycles, enabling the unit to function as a reliable production-line aging system.
- Four-Core Precision Sampling: Utilizes four-wire connection architecture to ensure high-precision voltage and current test sampling.
- Comprehensive Safety Protections: Features power-down data protection, reverse polarity protection, over-temperature cutoff, over-voltage limits, and short-circuit safeguards.
Benefits
- Professional Quality Control: Accurately verify pack capacity, performance consistency, and cycle life for electric vehicles and energy storage batteries.
- Power-Loss Data Recovery: If connection cables are accidentally disconnected during testing, re-securing the leads and holding the START button allows the test to resume.
- Efficient Thermal Management: Built-in intelligent speed-controlled fan runs continuously during high-load operation and delays shutoff to dissipate remaining heat safely.
- Streamlined Data Analysis: Export test reports directly to Excel and analyze detailed time, voltage, and current interval data logs effortlessly.
Applications
- Electric Vehicle & Battery Manufacturing: End-of-line testing, performance grading, and aging verification for industrial battery packs.
- Dealer & Service Workshops: Diagnostic capacity testing and health evaluation for returned or serviced battery assemblies.
- R&D and Laboratory Testing: Long-term cycle life testing and automated charge-discharge profile generation for new battery designs.
- Solar & Energy Storage Maintenance: Routine performance testing for large-scale lead-acid and lithium storage banks.
