This DJI Mini 4 Pro hidden accessory could cause a crash or it could save your drone... DJI may have a problem and they don't even know it yet... Ok, enough of the dramatics. We were contacted by PowerExtra Pro and were asked to test out a new DJI Mini 4 Pro accessory. Of course we were interested immediately because this accessory is something every drone uses. PowerExtra Pro has developed an aftermarket DJI Mini 4 Pro battery that seems to match the original DJI Mini 4 Pro Plus battery to a TEE. We took on the challenge and compared the original DJI Mini 4 Pro plus battery with this new PowerExtra Pro plus battery and quickly realized DJI may be in big trouble. This battery's spec are so close to the MIni 4 Pro plus battery it would be easy to think the performance would be just as good, right? Watch and see what happens during this test and you be the judge.
