Issue reading battery using cp2112. Cell voltage 3.5v #368

I'm having the same issue as a lot of people when using the cp2112.

After connecting the cp2112 to multiple DJI spark batteries and trying to read them using the DJI battery repaired tool I get the air that is unable to read.

I understand normally this is due to the battery not having enough voltage and sometimes external power is needed. I have all the cells charged up to 3.5 volts I am still getting this issue. I've tried you also provide 12 volts while trying to read and still not unable to.

The battery is connected to the Drone and trying charge over USB Led1 lights and stays on then immediately led2 lights. It does this a sequence four times then stops and then repeats.

If I connect a supply directly to the positive and negative pins try to charge that way the LEDs do the same sequence but when they do the battery pulls 500mv

ANY idea?
