Hello,

I was hoping to get some help putting a power supply together for my set of DJI goggles. The power supply voltage is 7.2V running off of two Li-on batteries. The factory power supply/battery system comes with propriotary stuff, however that isn't nessarily needed. I Just want to add a USB charging system and power indictor since I'll be loosing that in the goggles when I remove the stock BEC.

Any thoughts?

 

The power supplies for the IR goggles that I have seen, not recently, seem to be rather picky about the voltage. So I am questioning the benefit of producing a substitiute. The military supplies were subject to damage and no replacements being available. The replacements used a flyback oscillator scheme.

 

Does this help?

 

Well I was hoping to keep the stock battery and headband assembly as they are. With how the Goggles are put together and the mount I chose I have to take off the headband portion. So the battery in this case would just be attached to the back of the helmet like the old school NVGS. Also my plan would make it easier to transport the goggles etc. Anyway I don't wan tto do the Lipo mod since that takes the original battery board. Though I could buy a different pair of DJI goggles that has the same battery system and just take its board. However I think it would just as easy to make a decent, self contained battery ecosystem that could be plugged into to power my goggles.

In that case I'd look at making a USB-C breakout cable to access the power input and maintain charge on the batteries whilst still allowing streaming of video data to 3rd parties. Of course, if you're not streaming, then just a normal USB-C power cable to an external supply/battery pack is the simplest option.

 

So I'm really planning on doing a number to these Goggles in the long run. I'm disconnecting all of the antenna, two of which are in the brow piece and stink anyway. Thankfully they're all easy to access etc. I'm having the same person I designing the box building the new SMA mounts for the new antenna. I was going to have him use the NVG mount as the anchor point. And this battery system is just delivering power. I asked Gemeni, because why not and its answer isn't that bad. I was just hoping to get some opnions on possible better hardware to use that I might not be aware of. This was its suggestion for a new BMS. https://www.newegg.com/p/3C6-00SS-0...6e08cd7450cbbdddc64c6cf2e8891f6d48747c6d56d2c

 

A simple power supply would be a string of five NICAD batteries at 1.2 volts each. BUT do you know how much current the goggles require?? AND what is the minimum voltage that they will operate with? OR does the supply need to be exactly 7.200 volts??
