Every DJI battery model (Mavic Air, Mavic Pro, Phantom, Inspire) has a different pin layout. You must look up the exact diagram for your specific battery to identify the , SCL (Clock) , and SDA (Data) pins. Step 2: Connect the Hardware
This guide explains what this software is, how it works, and safer alternatives to revive your drone batteries. What is DJI Battery Killer Software?
Open the software. Select the correct connection port and adapter type. Click "Connect." If the wiring is correct, the software will read the battery's chip data and display info like cycle count, cell voltages, and error codes. Step 4: Clear the Errors The user opens the DJI Battery Killer executable,
Is your DJI drone battery showing no signs of life, despite your best efforts to charge it? Many DJI drone pilots—from Phantom to Spark users—have encountered the dreaded "dead battery" scenario where the battery management system (BMS) shuts down permanently due to over-discharge or a software bug. While DJI support might tell you it's time to buy a new one, a powerful community tool known as can often revive these seemingly bricked batteries.

It is also worth acknowledging the official alternatives. For safe discharge and storage, DJI's own software can be used to put batteries into a storage mode, helping to prevent lockouts in the first place. For disposing of old batteries, DJI recommends fully discharging them (by running the drone or using a power bank adapter) before placing them in designated battery recycling bins, not in regular household trash. Its key pins are: Downloading the DJI Battery
If you are an electrical engineer or a drone hacking hobbyist, you can find the original dji_battery_killer source code on GitHub. But for 99.9% of users, any software that claims to be a "DJI battery killer."
Using the DJI Battery Killer software or similar tools poses significant risks to the user, the drone, and bystanders:
