The DJI Battery Killer software alone is insufficient. The software communicates with the DJI battery's BMS using the (Inter-Integrated Circuit) protocol, a common standard for low-speed computer peripherals. A specialized hardware bridge, the CP2112 HID USB to SMBus/I2C Adapter , is needed to connect a computer's USB port to the battery's I2C pins.

There is for this tool, as it bypasses DJI’s safety protocols.

The software's original hosting site is currently dormant, making the Internet Archive the most reliable source for the legitimate file. The most widely cited stable version is ver. 0.5beta2_01.02.2022 Operating System: Windows executable (.exe)

If you want to troubleshoot your specific hardware setup, tell me: What do you have?

Select the correct adapter port in the software and click "Connect." The program will display the battery's chip data and error log.

The software communicates directly with the battery management system (BMS) chip inside DJI batteries. When a DJI battery drops below a safe voltage threshold, the BMS triggers a permanent lock flag (often called a "PF flag").

The software's primary function is to communicate with the battery's BMS via a hardware bridge. Its key capabilities include:

You cannot simply plug a standard USB cable from your computer into the drone battery. The software requires a hardware bridge to translate commands:

The BMS stores calibration data. Unofficial software rarely respects the CRC checks. You might permanently corrupt the battery's firmware, turning a $160 battery into a paperweight. DJI will not repair or replace batteries damaged by third-party software.
