Dear sir, this is my second X4 storm, the first one flew away and can never find it but because i like it a lot, I bought another one, it flew good few times and suddenly it will not power up, no crash or nothing. When i connect the battery, the battery light comes on very dim, hard to see and other lights or flashing, but when I connect usb, it works great and bind and everything works, I tested with 2 batteries, same thing, i tested voltage at the board where the battery connect and it is the same voltage like the battery, is the mother board bad? please help me, I am devastated but dont want to buy a third one specially that I have 2 of everything now except battery and drone. Thanks in advance.

All 3 videos are the same, if you can open one of them, you will see.
Battery is fully charged and the voltage of the battery is the same at the board.
Notice the dim red light in the back when the battery is connected alone?
With Usb, everything works well.
it was not crashed or anything.

Thanks for your video,would you mind to tell me the volt number of the battery when you full charged?

Battery voltage is 8.4 volts, I also tried with another 2 cell battery I have, same result.

Hi Kindly test the volt number of the place where I quoted in red color. Especially note that if there have 5 volt in where battery output.

At the battery outlet, there is 1.57 volts, when connect ohmmeter between outlet and inlet, it reads 6.93 volt, battery alone is 8.43 volts.
