: The software is designed almost exclusively for Windows operating systems. How the Software Works (General Process)
Consider recycling the dead battery at an e-waste facility and purchasing a new one. The question isn't always if you can revive a battery, but if you should .
The CP2112 adapter connects the battery pins to the PC's USB port.
Opening a battery or altering its firmware instantly voids all DJI warranties and DJI Care Refresh coverage. Safe and Official Alternatives
If you understand the risks, possess electronics experience, and intend to use the tool purely for educational or laboratory recycling purposes, the code is hosted transparently online. dji battery killer software download
Opening battery casings with metal tools can puncture LiPo cells, causing fire or smoke.
LiPo batteries are volatile. If the software forces the BMS to ignore the low-voltage cutoff, the battery will drain below 2.5V per cell. This causes copper shunting (internal short circuits). If you attempt to recharge a battery that has been "killed," it —potentially in your home or car.
DJI drones use Intelligent Flight Batteries that lock themselves permanently when they detect deep cell discharge or internal errors. This safety feature prevents dangerous battery swelling or mid-air failures, but it also leaves users with expensive, non-functional plastic bricks.
Once unlocked, immediately place the battery on a low-current external power supply or a standard charger to bring the cells back to a safe operating voltage. The Critical Risks of Reviving Locked Batteries : The software is designed almost exclusively for
Because this is community-developed software, it is not hosted on an official corporate website. GitHub Repositories
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
Disconnect the battery and immediately place it on a standard charger to see if it accepts a current. Severe Risks and Safety Hazards
It wipes the permanent failure flags (like Over-Discharge Protection) from the BMS memory. The CP2112 adapter connects the battery pins to
However, the tool has also been used to "recondition" used batteries for resale. This process, likened to "resetting the odometers on cars," can involve resetting cycle counts, making used batteries appear like new. While DJI Battery Killer is a free community tool, other commercial or paid software options offer similar unlocking capabilities.
: Cheaper alternatives used by DIY enthusiasts to mimic the EV2300 interface.
DJI batteries lock down for a reason. If a LiPo cell drops below a certain voltage (usually around 2.5V to 3.0V), its internal chemistry degrades. Forcing a deeply degraded or shorted cell to accept a high-current charge can cause . This results in intense, toxic fires that are incredibly difficult to extinguish. 2. Mid-Air Power Failure
But a software tool can't reverse physical damage. A battery that has been deeply discharged or left to swell is a fire hazard. The financial savings of reviving a $90 battery are not worth the potential costs of a house fire or a drone crash.
