I just got a set of Aomway commanders. These goggles work with 2s to 4s batteries, well I tried 4 different fully charged 4s batteries on them today and they will not power up.
Has anyone else had this problem or know the answer.
I spoke with you over email, but just incase anyone else has a similar issue, the porblem was with the filtered power supply unit. But if your goggles are not turning on its worth checking the battery itself is charged, and then use a voltmeter to check if the filtered power supply is outputting any voltage to the goggles.
In your case we will get a replacement power filter sent to you tomorrow 
But the other option is to use one of the fatshark style batteries directly with the headset.
I have checked the out put from the power filter with a freshly charged battery.
Thank you so much for helping resolve this issue so quickly.

We sent you out a replacement power filter so if it’s not there already it will be with you soon, so hopefully it will all work now
It arrived today and worked perfectly. Great customer service and a great product I will be shopping with you again.
