I hope someone will find this useful.

For most, it's the absence of a power button. For me, plugging and unplugging a balance lead to get the fan going is actually the worst, then having a battery on the side of my head, finally followed by the power button. All that after spending $500!

Slaytech extension cable is actually a good product but it doesn't solve the balance lead issue and adds another barrel connector that needs to be plugged in. It appears it's not that difficult to address both problems.

If you decide to follow the description below, please be very careful to avoid ruining your very expensive goggles. Always check and double check polarity with a multimeter. Use the continuity mode to check for shorts before plugging in. Also, the warranty will probably be void with these mods.

Pry open one of the two black covers of the 18650 battery case. It has two screws through it - I have found it out after opening it. You should locate the screws under the label. Alt Tag

Cut off the balance lead and barrel connector from the extension cable. Isolate whatever is left of the balance lead wires on the extension cable NOW (make sure the two wires never connect)

Remove the board from the case and unsolder the old wires from it. The terminals on the board are marked Batt- (with black wires) and Batt+(red wires). Solder the extension cable wires along with leads that go to the battery contacts to the board. The extension cable wires are red and black. Still, check the polarity! Outside of the barrel connector is ground, inside is positive. Tack the board and wires back in.

Close the battery case.

On to the goggles! You don't need to fully open them to solder the cut-off balance lead to the power connector inside of the goggles. Just popup the face plate and open a cover near the power connector. Unscrew two screws - one from the bottom of the goggles below the cover you just opened and another one holding the board inside the bay. Now pry open one side of the goggles, remove the strap and the electronic board that has the power connector on it.

Insert the cut-off lead through a hole in the side where the strap attaches to the goggles. Solder the lead to the connector contacts from the bottom of the board. Use a multimeter to determine polarity of the contacts! Insert the board in and screw the screws back in (see the red and black wires on the back in the picture)
Alt Tag
Attach the face plate, the strap and plug in the lead in to the fan connector and LEAVE IT THERE. No more unplugging! Alt Tag

It's done! Enjoy!

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success.
