Kazhuu Builds WebUSB App for EBC-A20 Battery Tester at 9600 bps

Summary
Kazhuu released a browser-based controller for the ZKETECH EBC-A20, letting users run battery load tests and graph results without the device’s default proprietary software.
A reverse-engineering effort mapped the tester’s serial protocol, which runs at 9600 bps with 8 data bits and odd parity, providing the command set needed to control it.
WebUSB connects to the tester through a USB-to-serial adapter, and desktop versions are also available for Linux and Windows.
The project targets users unhappy with the stock software and shows the EBC-A20 can be driven through a relatively simple serial interface.
