The EBC-A20 is a high-performance, multi-functional battery charge and discharge capacity tester designed for 30V lithium, lead-acid, LiFePO4, and ternary lithium batteries. Featuring a maximum discharge current of 20A, continuous discharge power of 85W, and 5A charging capability, it is engineered for precise capacity analysis and cell performance testing. Built with advanced four-wire Kelvin detection, it measures voltage and current through separate channels to eliminate cable resistance, ensuring accurate results down to 0.003V. The instrument includes a backlit LCD display and supports PC connection via a USB-to-TTL serial cable. With the dedicated PC online software, users can program automated charge-discharge-charge cycles, generate detailed real-time voltage/current curves, calibrate benchmarks, and upgrade device firmware.

Features

4-Wire Kelvin Detection: Separates voltage measurement and current delivery channels to negate lead resistance for precise testing accuracy.
Automatic Cycling Mode: Supports programmable "Charge-Discharge-Charge" auto-cycling to evaluate full battery capacity effortlessly.
High Discharge Power: Handles up to 20A high-current discharge with a maximum continuous power limit of 85W.
Multi-Chemistry Compatibility: Performs testing on Lithium-ion, LiFePO4, ternary lithium, and lead-acid batteries.
PC Software Control: Connects via a dedicated USB-to-TTL serial cable to plot real-time discharge curves, record data, and perform firmware updates.
Backlit LCD Interface: Displays critical test data simultaneously, including real-time voltage, current, capacity (Ah/mAh), elapsed time, power (W), and energy (Wh).
Versatile Operating Modes: Supports Constant Current Discharge (DSC-CC), Constant Power Discharge (DSC-CP), and Constant Voltage Charge (CHG-CV) modes.

Applications

Capacity grading and health verification for DIY lithium battery packs.
Testing capacity and discharge performance of 12V / 24V lead-acid batteries.
Solar energy storage battery cell testing and matching.
E-bike, power tool, and scooter battery pack internal resistance/capacity evaluation.
Laboratory research, electronic repair shops, and quality assurance inspection.

Usage

Plug the tester into an appropriate DC power source (DC 19V-20V, ≥3.5A).
Connect the four-wire test line aviation plugs firmly to the front panel sockets.
Attach the positive and negative test clamps to the corresponding terminals of the target battery (observe proper polarity).
Use the control panel buttons (SET, INC, DEC) to configure discharge mode (DSC-CC / DSC-CP), cutoff voltage, and discharge current.
Press the ON/START button to begin testing, or connect the USB-to-TTL cable to a PC to control and record tests via the EB Tester software.

Maintenance

Keep the cooling vents clear and clean the internal fan periodically to prevent overheating during high-power 85W discharges.
Check test lead connections regularly to ensure low-resistance contact with battery terminals.
Store the tester in a dry, dust-free environment away from direct sunlight and moisture.
Avoid exposing the unit to input voltages or discharge power exceeding specified safety limits.
