Flying Long Range FPV with the GNB 7000mAh 70c LiHV Battery

- I was quite surprised by the weight VS capacity & performance of this GNB LiHV battery. GNB has been slowly lowering the weight of their lipo packs while also increasing the capacity at the same time. This battery provides for some long flight times while still managing to put out more current than any li-ion pack can.

Cool. Those motors are monstrous on 7.5"! I'm running the 1500kv 2808s on my 7" and it's borderline scary. Cheers -
I"m glad you finally got a chance to try the HV7000 packs. They are awesome - I love them (as you know, hahah!) . I've used lots of HV packs and something that you need to keep in mind is that they don't last nearly as long in terms of usable cycles as regular lipos. The chemistry starts to die much more quickly when charged to 4.35v. What I do is charge them to 4.1v (or sometimes 4.2), then in the field I'll top them up to 4.35 so they are at 4.35v for the minimum amount of time possible. This should extend the life of them pretty dramatically, otherwise you're probably going to start seeing them degrade after 20 cycles or so depending on how long they sit at 4.35... and they are expensive batteries!
ah yes, that's what I was expecting. I'll try your idea of charging to 4.2 and then topping the battery off to 4.35 just before using it.
Holy, that pack is huge jesus.
You are becoming a GOD of Flight...... you know this YES
Amazing video,thanks for sharing!
Beautiful lighting conditions. Great flight. Interesting commentary. Thanks!
This just may have put me over the edge... I think I'm going to build me one of these!
Dude, your vids always make my day! Seriously, I'm stoked when I see that notification pop up, and you never fail to bring the goods. Watching those sick scenes is pure bliss, and your insights? Bro, they're like nuggets of wisdom. You're basically the FPV encyclopedia, (as my friend Giant Ant Cowboy). And btw, those mountain-top views are straight-up epic. Thanks for dropping that vid, my friend! Oh, and for real, this winter in Europe is wild - it's midwinter, and we're rocking 17°C! Crazy, right? A few years back, on this day, it was a bone-chilling -29°C... times have changed, man!
Thanks so much for the comment!

Great video!
Omg thanks so much for bringing me up here super awesome ❤🙏🏞
Pretty amazing flying and footage, dude! 😃
Stay safe there with your family! 🖖😊
Thanks, you too! 👋👍
Great vid as usual!!
Appreciate that
nice!! mountain overflight is cool, the over water passes were epic!! man that's a pack up there looking like a mini fridge!!
Thanks 👍
@@FalconRadFPV You're welcome!!
Very cool video again! 🍻
Thank you! Cheers!
amazing
GNB lies the most about their specs compared to all lipo batteries I've messed with.
what I've found is they fall off a cliff at 3.3v and will fall to 2v in seconds, whereas I can trust the CNHL lipos to last materially longer at that voltage
GNB has always been good for me. I buy their LiHV alot. Lipo alot of times I buy Tattu or think bought iflight once
Hello, I've been following you on TH-cam for a while 😉. I love your long range videos, it’s incredible 😍. on the other hand I find it a shame that you do not offer already built quads
I keep thinking about building BNF long range drones to sell, but it's really tough to compete with the prices of ones that are built in china. I am still thinking about it though, since I can't beat the iflight and GepRC prices I may go for a high quality type of build, like including a diversity RX and good quality antennas for the RX and VTX as well as the benefits of my frames designs.
Pretty sure you could exist in a niche. Don't even think about competing with iFlight though. Go for the prosumer and pro market and price accordingly. You can't make many and the market is quite small. Got to be north of $1000.
GNB has been problematic 😳 since i bought a couple. Especially not holding charges staying away from them................
If you're using helicals on the DJI goggles then you need to check that they have a low VSWR. A low VSWR doesn't matter much for analog because the analog goggles don't transmit but the DJI goggles do and a high VSWR will produce very poor transmit performance that could significantly affect the link.
I always spend a bit of time with a VNA to make sure the VSWR of my helicals is as low as I can get them.
Thanks for the tip! Still learning the DJI stuff. And thanks for your earlier help via your videos. That was part of where I learned to make them!
Range on the o3 looks great here!
The 03 has great range, it goes as far as you need, at least for a drone flight.
I fly with 4 helicals lhcp 2-6in 2-10in. On my dji vista's fpv planes/ wings
I’ve experimented with connecting one Helical to two SMA ports on my HDZero goggles, and up to a certain point it worked great to a certain point then the performance seemed to rapidly dropped off!
I think it’s because it’s splitting total signal power which mainly affects performance when signal is weak… (We gotta ask Hugo)
but I’ve also been meaning to test this more.
Would be nice not to need four antennas all the time.
Nice video as always, cheers bud.
Thanks for the comment, that's an interesting idea. I actually had two antennas where it looked like one, they were just intertwined on the same holder/mount. Still trying to sort out if they interfere with each other that way.
@@FalconRadFPV oh yea! I see it now, that’s really interesting, love that idea. Would love to hear if it works well, maybe I’ll give it a shot as well.
Similarly, I’ve been wanting to make/test a “Double Helix” antenna, there’s not much information about that design, but a guy Andrew McNeil did a video about this many years ago.
Damn thats a massive battery lol. So you use helical antennas for lhcp or rhcp without doing anything special to em? Awesome video, I love these long range mountain surfing videos.
They are circularly polarized so you need to make it either left or right hand polarized. (I made my own)
@FalconRadFPV so for helical antennas it's just the way the wire spinds. Left or right?
Awsome video i get the rad li-ion frame today gunna be epic trying some 03 long range with the goggles 2 and see what we can do,🤙
Awesome, let me know if you need any helps with tpu mounts or whatever.
@@FalconRadFPV sure will if have trouble finding something or need your help I highly appreciate your replys. I have my buddie custom makeing mounts for me ...I have the 03 mount ...03 camera standoff mount....gps and antenna mount and he is custom makeing a diversity mount for the elrs ...and few other things...super excited to get it built I really lile how much you push long range keep up the awsome videos man🔥🔥🙏
709g at 7Ah 22.8V = 225Wh/Kg! That's even better than their 60C purple HV packs (~190Wh/kg) i've been using, not bad for a LiHV! Unfortunately 7Ah/160Wh is too large for me as I can't take em on planes (100Wh carry on limit)... If they'd sell some smaller say 1/2/4Ah versions for smaller quads and I'll buy a few to try! Nice flying though!
Nice, wish i had scenery like that to fly around, Wisconsinite here... Have you tried bi-blade props, wondering about the difference in feel and i know when i use to fly my flame wheel 450 back in the day, balaneing props was a pain.
I've tried bi blades but find that tri blades are smother and I'm always recording gopro footage, so smoother means crisper footage.
O kurwa jakie ujęcie .
So for the 2 seconds your video froze, did you just fly through it? How, much longer would you have waited till you hit RTH if it stayed frozen? Thinking about picking up this pack for my 7'' hopefully not too big.
I just try and hold steady for a couple of seconds and if the video loss lasts longer than 2 or 3 seconds then I'll hit GPS rescue.
Fantastic video and great scenery. I am expecting any day to see DJI release the O4 FPV version as they have already released it on their air 3 and mini 4 pro drones. But you would have to upgrade your goggles to the goggles 2 or goggles integra. I have the Goggles 2 with my Avata. Which the avata is still using occusync 3 but it gets great reception. I have a couple FPV drones as well that I want to upgrade to the DJI O3 unit. I would love to have those mountains to fly at their absolutely breathtaking.
I'm on walksnail but always interested in what DJI brings out, wish I could use them actually but my ipd is too wide, heard that there may not be an 04 air unit and it was just put on the other drones so they could use goggles, should find out pretty soon.
That's the one thing I don't like about DJI, they stop supporting past hardware quite quickly it seems. Makes you need to upgrade often which seems like a sales grab. All that said, damn the 03 air unit looks great (on all the goggles).
@FalconRadFPV I,m also using the v2 goggles with the o3 and the combo is awesome.
If they bring an o4 air unit we dont know about the compatibility yet,if it is compatible with the Goggles 2 it will be also compatible with the v2 goggles.
Or o4 will be only compatible with the Dji Goggles 3! Thats the other scenario.
But for now all we have to do is enjoy the o3!😎
@@FalconRadFPV But they did support Vista on G2s and O3s on V2. It took some time but maybe DJI is listening a little bit :)
@@FalconRadFPVsoon you'll have openIPC open source HD. No longer need for DJI!!
Awesome video man! Just wondering what frame rates you have set so the snow isn’t over exposed when you get above the tree line? Do you just use auto for this situation?
I just found an older video of yours answering all of my questions. Amazing!
I might make an updated gopro setting video now that the hero 11 and 12 are out. But ya sometimes auto or else usually 1/120th shutter, and just locking it and the ISO down low and deal with the river portion being too dark so the nice snowy footage won't be blown out. Backlit clouds make it tough, on a blue sky sunny day its much easier to find the right setting to lock it to. But also on a sunny day auto works ok as well and doesn't shift around as much. ISO as low as possible is pretty key, I won't go above 200 on my 11 mini.
Hi FalconRad. Great video once again! I have a question if you could find the time to answer. I'm also interested in using big lipo packs for long range but most of the batteries of that size in my country come with a xt90 cable while my quad uses an xt60. Is it ok to use an adapter (xt60 female - xt90male) in order to achieve this, or am i risking it?
Yes that's fine, I use an adapter for xt60 to xt90 sometimes. You can also just cut the xt90 off and solder on an xt60. (for safety do this when the battery is at a low charge, like 3.5v)
@@FalconRadFPV Thank you for the reply FalconRad. Take care!
🙌🏽so much faster! 🔥 river speed runs!! 🫠
Sweet lr flight, I looked at the GNB 7000ma 6s battery and I wish I purchased it instead of the liion 4500ma lion I just built. I have a Source one 7in v5 that I used 2808 1100kv toka motors, but im still testing it before I start climbing some mountains. Did you build your google Helix antennas ? I just don't see them in your part list. Thanks for the info
Use the new gemfan 7050 on those motors. You will like it
I have a video about how to make the antennas here: th-cam.com/video/aH0cW9XJ4D4/w-d-xo.html
Can you make a video or write here explaining your methodology around which of your frames are best for what? Im trying to decide on one of your frames since i hate the history of the fr7 and want no parts of it .....
For really stable cinematic/long range the Falcon RPM. For the best range possible (but still a priority on gopro quality) the RAD Li-ion. If your all about range and don't care about gopro footage then the Rad Scout. Then just for the heck of it, I'll be adding an octocopter to the frame line up in the next month or so (regular and long range versions)
I was curious to try a large LIPO on the rad-Lion !
One this size would need to be bottom mounted, unless you did some sort of FPV camera & GoPro out front mount thing. I've done it before, mounted the GoPro out in front of the drone and the FPV camera on top of that. It would just take some work getting a good design figured out.
A new video with setting betaflight be helping , because my falcon 7 have a problem with trottle , when i descend trottle 0 , a motor spin again and i dont go down , with 4.1 i dont have a this probelm ,but with 4.2 and 4.3 i dont succeed my setting
If it spins up the motors and isn't descending when you lower the throttle, my first thought is to try lowering the D-term filter slider by 0.1 - 0.2. Did you use the same PID's in 4.3 as you did in 4.1? I think for 4.3 the PID numbers are calculated differently so the "tune" needs to be different, and I'm fairly sure the PID numbers should be lower in 4.3 than in 4.1. So you could also try lowering the PID master slider by one or two notches, that also might help. I have been thinking about making new videos for betaflight 4.4/4.5 settings for all of my different frames. It's not very good weather this time of year right now, once we start getting less rain I'll be able to do tuning videos more easily.
Beautiful… so amazing… Q: Since most LR FPV is gentle flying, do you see an advantage over a 10,000mAh LiIon pack like the Dark Lithium packs? Those seem to be the best 7” battery out there…
The disadvantage is the weight, it fly's poorly as far as agility goes. But yes you don't need to be agile to get good long range footage. Compared to a 5000mAh, the 10000mah on a 7" only gets about 40 or 50% more range since it's starting to push the limits of efficiency VS prop loading. I find that almost every flight I do I can make it with 6s2p 18650 packs with a total mAh of 5600. They'll get me 9 or 10 km out (and back of course) if I wanted. I rarely use my 10,000mAh pack, I save it for when I want to be able to reposition and try at several different shots on the GoPro while up a mountain, it gives me several extra minutes to redo a couple of shots multiple times.
@@FalconRadFPV Thanks for the reply. The 10A/Hr packs from Dark Lithium are my go to packs. I don’t have much experience with LiPolys in this application. I tweaked BLHeli_32 for max efficiency and can fly about 30minutes on 7” props. My frame (AOS7ULR) can fit 7.5” props but the clearance is only 1/8” per side of the battery so I don’t risk it…
What do you think about 7.5" vs 7" for long range? What props do you recommend for 7.5 (those gemfans you mention?)?
The Genfan 7535 are what I use. They seem to work quite well, minimal vibrations. I think the HQ's are fairly similar as well. You do need a slightly bigger motor to spin the 7.5" prop well. I'd recommend a 2808, 2810 or 3008
how is diving with that big battery? do you think a stock chimera 7 could hold it? Im always pushing the range of my lions and lost my drone several times. Check out some of my Alaska FPV adventure vids!
Ya the chimera 7 should be fine with the same lipo. Being an HV lipo it's weight isn't too bad.
Do you think a 3d printed frame can ever compete with a traditional frame? How much less efficient do you think it is?
I’m just so interested as with a 3d printer you can endlessly customise.
It's not about efficiency, it's about the rigidity of the materials. It's tough for a 3D printed material to compare to carbon fiber plate. It would need to be printing with a very strong and very stiff material which is extremely durable. Anything less than carbon fiber for big frames and it's just way to much vibrations for the flight controller and motors to handle.
Hey bro.. I learn a lot just reading through the comments.. lol Can’t believe nobody asked what the flight time ended up being? Watched the video twice and read through the comments.. if you said it I missed it. Sorry.
I think it was about 18 min give or take a minute.
Are you also still flying LR on 8S ? Or don't you see a benefit?
I'm flying my latest 7" build on 8S and really like it. Don't want to got back to 6S.
I've only done testing with 8s really. I have 2 8s builds but only use one of them every now and again. I made my 8s build as my extra range scouting quad but I always use my regular Rad Li-ion or Falcon RPM builds for recording footage for TH-cam. I'm looking to do an updated 2024 Rad Li-ion build in the nice 8mm arms version of the frame and using the new t motor f55 pro 8s ESC. When I get that build done I'll start having more 8s content for sure. I should get on that......
What was your total flight time and total flight distance? I'm considering buying a pair of these li-pos and doing my research before the purchase. Thanks for your time.
This flight I got 16 1/2 minutes about about 16km.
Awesome! What gps are you using?
This build has my old brainfpv gps on it. The gps still works great. But if you're looking to buy a new one go for an M10 gps the performance is noticeably better between an M8 and M10 gps.
Awesome advise! I have the iflight m10 blitz on order.. I believe that’s what is on the Helion 10.
Hi Falconrad thanks again for another amazing upload, but may I ask for some of you help or maybe someone in the comments can help, what I am trying to do is, for example in the North York Moors National Park here in the UK , lots of people get lost and need help to find their way back to safety, so my idea is to make 1 of Falconrads long range FPV drones use it to go and find these people, and then be able to drop of to them a small radio, so what I am asking is can I some how fit and operate a 9 gram servo to the drone being used in the video, so that I can then be able to drop off the radio to the people who need help, when I find them? and if so how do I do it, thanks for your kind help.
Wow, cool idea. Yes that can be done. Both Inav and Betaflight have options to control servos as part of the firmware. I don't think it's hard to get a servo to operate with either one of them. Just search betaflight servo control or inav servo control. I'm sure you'll find a few videos talking about getting servo control setup. There is for sure space underneath on the frame to hold a small radio.
Hi FalconRad thank you for the info I will check out what you're saying , thanks again for all the amazing uploads on your channel 👍👍👍💯💯💯@@FalconRadFPV
How long did it take to get this level of confidence in your quad?
When I build a new quad I'll just do a couple of test flights before going on to flights like this. I'd do one halfway out to start and fly the battery down to empty and write down the mAh used and ending voltage and then ready to go all out. For me I think it's more about confidence in the gear than the individual builds. I know what all the gear is capable of and feel comfortable expecting a certain result with minimal testing. Keep in mind I've built LOTS of long range quads and just know how to do it well so it's easy to avoid antenna reception issues, electrical interference etc.... I guess maybe it's confidence in my ability to assemble a quality build
Do you think you might run the 03 without a gopro?
\If I'm flying for just fun then ya sure. But if I'm flying to get footage then the GoPro is what I'll use, it's just a big step up from the DJI 03 footage, at least in some lighting conditions.
what antennas are you using for the dji o3?
I've got TrueRC Singularity antennas on the 03 air unit and on my goggles its just two of the DJI stubbies and the iflight crystal patch.
Can't find anywhere to buy that battery. I wanted to try it on my 10 inch
ya it's not very easy to find, not many people use ones so big. I bought it at rotor village in canada.
What was the flight time you were able to achieve?
It was a 17 minute flight covering about 18 kilometers.
Only get about a mile with my Vista and my v2 goggles on 1200mw. Any help on new antennas or what to try?
that doesn't sound right - I've been out 4 miles on 800mw (haven't done the hack) - I'm running TRUERC antennas on quad and trueRC stubbies + the iflight crystal patch on my v1 googles.
As the other reply mentioned, upgrading to TrueRC singularity antennas should help. But for good range the TrueRC X2air is really great for the goggles.
Had to get a new ufl antenna and works good now
Man I've heard of a few people having issues with the hero 11 mini
oh ya, possibly the most unreliable gopro so far, just the mini's. I'm on my third one now.
Traditionally, LiHV have lasted only a fraction of even ordinary lipos... I wonder if "they" have "fixed" the problem, yet...
As far as their life... the ones I have used, the highest c rated ones but only the smaller 650 ones, seem to not last as long either, think it's because they are pushing the cells to the limit, even regular lipos will last longer if not charged all the way to 4.2...
May last longer if you only charge high volt to only 4.3 or something
I might try that, just charging up to 4.3, the last bit hold hardly any mah anyways.
Agreed, lihv doesn't generally seem to be worth it, the longevity is MUCH worse
Will you ever make a 10" or 11" frame?
I made a flew an 8" RAD Li-ion, but I didn't really fly it very much, I still preferred the way my 7" was flying. I'm halfway through drawing up a 10" version of the Falcon RPM frame, but it's a lot of redesign since it doesn't just scale up like a typical X frame does.
@FalconRadFPV yea and I been looking 6s vs 8s and battery sizes & weight for big packs. Like 6s4p and 5p. 3314 motors or 3115 .. if u don't make one I figured I'd look at chimera cx10 & geprc pulsar lr 11"
Where do you buy helical antennas?
I make my own, but some FPV store do sell them, just google "fpv store helical antenna" or make one like in this video:th-cam.com/video/aH0cW9XJ4D4/w-d-xo.html
@@FalconRadFPV I have bought one from the store but it looks that your antennas are much better.
How to make remote control tree and building barrier free?
buildings will always get in the way of the signal, unless it's only one or two walls and you are close by.
@@FalconRadFPV This means that we still haven't found a signal that can penetrate walls or barrier materials...😔
Oh man i dont think these fit my small frame. Im not sure., I have lumineer cinelifter 6s 3500mah i have used that is 140mm it says. and it just barely fits I think gopro cant tilt back.
these are also 140mm long.
@FalconRadFPV yea doesn't fit with gopro. Think absolute max is 134mm 🤔 unless I don't run gopro
Umm that almost li-ion pack mah per gram
Ya it's quite energy dense, I think the lifespan will likely be the weak point.
@FalconRadFPV I just went and looked at a bunch. 6000, 6500, 7000, 7500, & 8000mah (only has xt90)
Be really close of it can fit my drone
The GNB brand is garbage. Very poor quality in my experience. With multiple sizes.
ya a few people have made similar comments. I'm still deciding....
I just bought RCHackers 6S 6000mAh 22.2V 100C Lipo Battery
It was a better deal than the gnb with higher c rating. Will try it in my FalconRAD 7.5”
My experience with GNB has been great ¯\_(ツ)_/¯
Interesting, I’ve had nothing but luck with the smaller GNBhv in 3, 4 and 6s.
