DJI Goggles 2 powered by an external LiPo using the SpeedyBee Goggles BEC

[@paulclement3235]

My friend just sent me a screenshot of this product. SpeedyBee products are awesome. The engineers surely have their gray matter in mass abundance, Love Speedy Bees mind set. Even the FC has LED'S on the edge to check Lipo energy level on your quad. Thanj you for your great reviews. You are a good teacher.

Thank you so much! I've had my mavic Air 2 for a couple years but have just recently been really getting into flying. I bought the DJI fpv combo (drone, rc, goggles v2) on sale as an impulse and I'm so glad I did. I haven't actually flown it yet other than just testing it. I have already rooted the goggles and put FPV WTFOS on them for more OSD stuff and plan to use them with analog DIY builds that I am looking forward to making. Going to go fly the fpv for the first time today. I'm super excited! This video probably saved me hundreds of dollars on having to buy those stupid batteries. Thank you so much!

[@WhirlyBloke]

You're very welcome. That's mainly why this channel exists. To help and inform. Thanks for the awesome feedback.

[@WhirlyBloke]

Thank's so much for your kind words! I'm thrilled to hear that my video and demo helped you make the decision to order one. It's definitely a fantastic product, and I'm sure you'll enjoy using it. Happy flying!

[@GarethDix]

I got one of these recently too, awesome product and even doubles up as a lipo voltage checker

[@WhirlyBloke]

Thanks for checking out my video and leaving a comment. I'm glad to hear that you also got the DJI Goggles 2 and you're enjoying them. It's definitely an awesome product. Thanks for sharing your experience! If you have any other tips or suggestions, feel free to let me know. Happy flying! 🚁✈

[@rotormasher]

Ordered one from your link thanks, great video

[@WhirlyBloke]

Awesome, thank you!

[@Globalinvader2315]

That's a pretty awesome gadget! thanks for showing it off

Great review...thank you. I was looking for some information about this product reducing the voltage for use with the DJI Goggles 2 and you answered it exactly as I needed. Thank you...I "liked" the video, I "commented" on the video AND I "subscribed" to your channel. Well done.

[@WhirlyBloke]

I'm happy it helped you. And thanks for the great feedback.

You are welcome and have a good day. @@WhirlyBloke

[@beechFPV]

Flashing. How are you going to see that when you have the goggles on? I thought by alarm you meant an audible one not a blinking light

[@WhirlyBloke]

Thanks for your feedback. By the time the LiPo is below the cut off/low warning, the output voltage to the goggles will start to droop and you'll get the same messages in the goggles display as you'd get when the OEM battery is getting low. It's then time to land, and change the battery.

[@beechFPV]

@@WhirlyBloke would have been better with a slightly higher audible alarm so it doesn’t get to that stage though. Ezra line of protection

[@francis916]

@@WhirlyBloke Thank you for the review. I just ordered one. So I guess the battery percentage display on the goggle will stay at 100% and then suddenly it'll start dropping when the lipo battery hits 3.65V or so. Do you know how much time it'll give you before the goggles shut down? I'm asking this question because you might not be able to land immediately if your quad is quite far away. I did a quick calculation assuming a 3S 2200mAh and I guess it'll give me about 5 minutes or so until the voltage reaches 3.6V from 3.65V. Please share your experience if you can. Thanks!

[@lynsmith1096]

Good review and a very good bit of kit.

[@WhirlyBloke]

Thanks for your feedback! I'm glad you found my review helpful. SpeedyBee make great products and are particularly good at making slightly niche things that make our life easier.

[@sebastiandiaz862]

Does it work with other goggles using the conecctor 5.5x21 ?

[@larryoakley]

Excellent video!! (Subscribed)... Quick question though, Can I order this device without the cable and be able to use it with the original cable that came with the Goggles 2 ?

[@WhirlyBloke]

Unfortunately not

[@princesfpvdrones]

Wow awesome! I ordered mine!

[@novisfpv]

My brand new integra is not charging nor powering on, how can this be solved

[@WhirlyBloke]

Try using the original charger and a different USB-C cable or power outlet to rule out power issues. Check if the LED lights show charging, and ensure the port is clean. If nothing works, connect the goggles to DJI Assistant 2 on your PC to check firmware. Still no luck? It could be a hardware issue-contact DJI Support for assistance or a warranty replacement!

[@novisfpv]

@WhirlyBloke have tried all those, i guess warranty is in order

[@BadbabyFPV]

Hi I plug a 6s battery to the googles and now they don't work. Was wondering what I fried and if it's repairable. Thanks

[@kurtzFPV]

Will this also charge the integras? Thanks

[@WhirlyBloke]

It won't charge them, but it'll power them fine.

[@kurtzFPV]

​@@WhirlyBloke just a quick heads up. I ordered one overnight from Amazon before seeing your reply. They can be used as a portable solution for charging Integras! Charging mine as I type this. You just need as cable with USB-C on both ends, which was not included in mine. Thanks for bringing this product to my attention. Edit: It will also fast charge my mavic mini 3 pro and controllers and charge my radiomaster pocket and boxer.

[@langitbanujaya6280]

Can it use on hdo2

[@jkpisces]

hi i am confused . what if i plug in directly with a lipo battery ? why do i need a bec to lower down the voltage if the goggle input voltage can accept up to 11.1v?

[@WhirlyBloke]

It's a voltage regulator. So the output voltage remains constant regardless of the voltage state of your LiPo. Obviously there's a lower limit, but if you just plug in a LiPo it could quickly drop below the operating voltage of the goggles and they'd just turn off. Also the Googles 2 particularly have a very small operating voltage range - probably intentional by DJI so you buy their batteries. Standard electronics theory really.

[@jkpisces]

@@WhirlyBloke thanks for the thorough explanation , fully understand the need for one right now . appreciate it

[@upnorthFPVandEUC]

Is there anyway to get the voltage read out in the goggles to read correctly? In the V1 goggles I had to turn the low-voltage alarm off in the goggles 2 the low-voltage alarm doesn’t go off it just doesn’t show correct in the goggles…

[@Fly_High_FPV]

Is there a low voltage cutoff to keep from overdischarging your lipos? How do you know when the lipos is dead?

[@WhirlyBloke]

That can't happen in reality. By the time the LiPo is below the cut off/low warning, the output voltage to the goggles will start to droop and you'll get the same messages in the goggles display as you'd get when the OEM battery is getting low. It's then time to land, and change the battery.

[@VIFLYDrone]

If the output voltage decreases dynamically as the input voltage decreases, it will be better.

[@WhirlyBloke]

@@VIFLYDrone Very true.

[@Fly_High_FPV]

@@WhirlyBloke in reality? How hard would it be to have a low voltage beeper before cutoff? Otherwise i'll be murding goggle lipos all day

[@feuer6405]

щиро дякую 😊

[@OCD_FPV]

Just out of curiosity why don’t you run standard 2s lipo’s like the fat shark used to use? I have 2 3000mah lipos, they power the goggles until they read sbout 20% on the led indicators. I get about 2 hours per pack but they are only $18 a pack.

[@WhirlyBloke]

Thanks for your great comment and sharing your experience. Using 2s lipos like the ones you mentioned can be a cost-effective option, but there are a few reasons why the SpeedyBee Goggles BEC is a better solution. Firstly, the DJI Goggles 2 requires a specific voltage range (7-9V) to operate optimally. The SpeedyBee Goggles BEC voltage output precisely matches the requirements of the goggles, ensuring a stable and reliable power supply. Secondly, using an external LiPo with a voltage regulator provides a higher capacity and longer runtime compared to a standard 2s lipo. This is particularly useful during extended flying sessions as it allows for longer uninterrupted use for a longer duration. Lastly, the SpeedyBee Goggles BEC offers additional features such as voltage monitoring and protection, which can help prevent over-discharging of the LiPo battery. This helps to prolong the lifespan of the battery and ensure safer operation. However, I appreciate your suggestion and your cost-effective solution with the 2s lipos. It's great that you're able to achieve a good runtime with those batteries. Different setups work well for different people, and it's always interesting to hear about alternative options. Thanks again for your input, and happy flying.

[@Dorff_Meister]

I was out of the field ready to fly and discovered that (again) I'd forgotten to turn off my Goggles 2 and the battery was dead. I then eyed the XT60 to Barrel Jack that I use with my analog goggles and thought "hey that should work" and then (luckily) wondered "Hmm, what's the voltage range of the Goggles 2?" I'm so glad I Googled that before plugging them into my goggles. Correction: the Barrel Jack wouldn't have fit. So glad to see that!!

[@WhirlyBloke]

Nice and thanks for sharing. It's always good to hear other people's experiences.

[@davidboulton8557]

Mate which 1 do I need? There are 3 different 1s. I have DJI Google's 2

[@WhirlyBloke]

Goggles V2 or 2 are the best choice. I have both, but prefer the refresh rate and screen size of the V2 even though it's not such a high resolution. as the Goggles 2.

[@ภาคภูมิใจดี-ห3ป]

I use goggle1 V2 , why use ESC my goggle show low battery? my goggle show 8.9V and sound alarm.

[@WhirlyBloke]

I suggest checking your battery with a multimeter.

[@thomasschmidt5475]

Hello, I have a question. Is it possible with the SpeedyBee Google's BEC also supply power to the Radiomaster Zorro?

[@WhirlyBloke]

No, but the Zorro has an external power connector and lead, so you can just use an external battery.

[@megiMove]

Im a newb, but can i use a 6s battery with this adapter to my v2 googles ? Is the voltage to high or does it convert to a lower voltage so my googles can take it ?

[@WhirlyBloke]

It's always better to ask and no be confused 😀You can use any input voltage between 3S and 6S (12.6V - 25.2V) and the adaptor BEC maintains the steady 9.2V required by the Googles 2. This will also work with the Googles V2.

[@AirJourdanFPV]

One thing to note is that if you hold that button, it will power off the system so careful when flying that the module isnt tight in your pocket or laying upside while being pressed but something else!

[@WhirlyBloke]

Thanks for the info.

[@MTB_FPV]

Absolute game changer for £12.

[@WhirlyBloke]

It definitely is. I use it all the time. Thanks for watching.

[@killingfields5853]

The cable falls out too easily

[@francis916]

Hmm.. This product needs to be used with a lipo battery alarm. The output voltage of the BEC is constant at 9.2V and it doesn't go down even if the lipo voltage goes lower than 3.5V per cell. On Goggles 2, 8.7V is displayed and there's no change because the input voltage is constant. Yes, the BEC screen flashes but there's no way that you can notice the voltage drop of the lipo when you're looking at the goggle screen. I tested varying input voltages from my lipo charger. The situation could be worse if you use a 3S lipo because the BEC will shut down when the lipo voltage is lower than 10.5V. The error notification is displayed a few seconds and that's it; your goggles go blank. With a 4S or 6S, at least the BEC doesn't shut down even if the battery is ruined. SpeedyBee should have included an audible battery alarm to this product. It's such a nuisance to attach a separate battery alarm to the lipo when you want to put it into your pants pocket. Or, you'll have to remember to check the BEC screen from time to time.

[@WhirlyBloke]

Thank you for sharing your feedback. Your experience with varying input voltages is valuable information for potential users. Hopefully, SpeedyBee takes note of these concerns and considers implementing improvements in future iterations. It's understandable that having to attach a separate battery alarm or regularly checking the BEC screen can be inconvenient. Your input will certainly help others make informed decisions about their gear. However, I've been using this solidly for the last month without any issues, but I am using a 4900mAh 3S LiPo that only needs charging every few weeks. The issue really, is the Googles 2 has such a narrower input voltage range unlike the V1 and V2 googles.

[@francis916]

@@WhirlyBloke Thank you for your comment. I only received this product today so I haven't really used it. It might be okay in real cases, I guess. I am overly concerned because I crashed a quad once because I didn't check the voltage of an analog goggles; I didn't let it displayed on screen preferring a less crowded screen and I never fully spent a 3S 2200mAh pack before. After that accident, I have the goggles voltage displayed on screen and check it often. With this BEC, I'll be checking the BEC screen each time before the flight so it might be okay without a battery alarm; I'll have to use it for some time to be sure.
