Best Batteries for Your FPV Goggles 

i posted a video on my channel about an issue i am having using battery bank and a usb c cable. could you help me out. channel is aphixe

Thanks Al. There are many different models doing the same.

Just be ready to test one more than cable. My advice, but them from a place it’s easy to return if they don’t work as expected

Thank you. Yes, share your experience later on.

They are still useful, but unfortunately they get damaged easily.

Thanks Jose

Great feedback. Thanks for sharing!

Thanks Jukka

Hi. The link is in the description: amzn.to/3WrIgxN And the size of the barrel is there as well. DC5.5

Hi harmonica, Very difficult to do as you want because what you need are Chinese parts which can change name, manufacturers and shape from country to country. In my opinion you need a USB-C PD 10000 mah battery pack, and a usb-c to 5.5 DC which limits the output power to 12 or 9v. I hope this helps

@@NordFPV Thank you

Thanks

The fatshark/echine will work on walksnail, but the DJI battery won’t.

Most big powerbanks are actually lipo batteries. I have not seen cases for 21700, not really sure why. I’ve seen a couple of 3D printed options but nothing commercial.

A la orden!

Hi. I’m not sure what you mean.

@@NordFPV almost every portable power station like Ecoflow, Bluetti, Anker, Jackery etc has the 12v car socket (I guess its also called a cigarette plug - the thingy u had in the older cars) same, they can handle up to 10A so its more than enough.

Looks like you can’t. The DJI battery has something extra in the cable to identify the goggles. Maybe changing the cable. Voltage wise it will work.

Hope you enjoy it! Just be careful to chose and check the cable.

For what Orion? That battery has a 2S balance cable and a XT30 if I'm not wrong. Most of the goggles require a barrel connection. So unless you change the connection with an adapter, or cut and solder a new one, my initial answer will be no for most of the goggles.

Yes. But it has some kind of special Communication with the DJI equipment and the cable just work between DJI.

​@@NordFPV ok so if I plug the "vintage telephone cord" barrel to usbc to a pd powerbank it should self regulate and work fine?

@@samuelevinti unfortunately not because your powerbank is not DJI. A DJI cable works only with DJI batteries.

Hi. I can't tell you a specific time since it will depend on your goggles and how often you fly and so on, but I can tell you that I fly weeks with it and my walksnail goggles before I put it to charge again, and I charge just because it's low, not because it's finished.

I’m pretty sure you need both. The PD power bank is the only that will get to the right power, and the cable is the one which will control the voltage and avoid burning your goggles.

@@NordFPV ok awesome, thanks for your quick reply and clarifying! I’m gonna try my hand at powering the new walksnail avatar X goggles I just got in via this method, but wanted to be sure I wasn’t gonna fry them!

@@sprucescott9483check with a multimeter before connecting the power source to the goggles.

Hi. No, unfortunately you can't. The DJI cable works only with DJI batteries.

Unfortunately the stock DJI cable works only with DJI batteries. 🤷🏻‍♂️

@@NordFPV i see. Does the v2 goggles use 5025 or 5021 plug? I dont think you can use powerbank. Uts not the cable that sets the voltade but the device you're charging. The powerbank Will allways output 5v unless the device have have resistance

@@kringtheking2657The DJI V2 (not DJI G2) uses 5025 (the "big" connector). What you are saying about the cable is not true, and a very understandable misconception. There are cables that set the voltage of a USB-C PD, while there are other cables that doesn't. USB-C PD Protocol needs "someone" to tell the device how many volts it's going to provide. Normally, and I guess the standard was built for this someone to be the device (laptop, phone, etc), but cables like the one I'm linking, and using here, has the same chip inside the USB-C connector to become that "someone" telling the powerbank how many V they have to provide. When I look at my cables I have some labeled 9v, and some labeled 12v, and If I measure the voltage, as I do in the video, you will see only the powerbank and the cable, without anything else connected on the other end, delivers a different amount of voltage than 5v or the max the USB-C PD port can deliver.

Yes. That case works with the fatshark goggles both analog and avatar version

@@NordFPV Thanks. What batteries are used inside the case?

@@johnsnow2347 18650 batteries

@@NordFPV Got it, thanks. 18650 3.7v x 2ea batteries = 7.4v

Yeah… and many of these packs are lying about it and or the capacity

​@@NordFPVI have checked the specs of both the power bank you have mantioned, they both say li -ion and not lipo, are you sure about that? Thanks

@@blackclown6191I'll be very happy if they are Li-ion, but mine says LiPo, and many videos where people test similar batteries and open them you see they are LiPos. am I 100% sure? No. Do I trust what the manufacturer writ eon the back of the case? No. The only way to be 100% sure will be to open them, but I don't want to do that right now, I'm very happy with them the way they are.
