Li-ion vs. lipo for long-range ft. Lumenier NAV batteries

[@GetFPV]

Great comprehensive video! Glad you got a chance to give them a try, and the results are impressive!

[@colibrifpv]

I've really had great results with these Nav batteries so far... 17 minutes with a lightweight 5inch drone on a 3000mah 6s Nav battery!!!

[@Illustrious_Aerial]

Nicely done with good visuals and explanations. Thanks for helping the community!

[@colibrifpv]

Thanks a lot for your support, really appreciate it 🙏

[@Sonic_Ox]

This is really good information. On my 7" DIY build I have three different batteries I typically run. I have two CNHL LiPo batteries. A 1300mAh and a 1500mAh. And I have an Auline 4000mAh Li-Ion. I have not flown with multiple packs at the same time but I do see similar results as those you are displaying here between the two different chemistries. In general terms I get around 5 minute flight times from the LiPo batteries and a bit over ten minutes from the Li-Ion. I think I could go a lot longer with both types if I employed better throttle management and lost some weight. I appreciate you producing these videos confirming what I'm seeing regarding the differences between the battery chemistries. One interesting note from my informal testing is that I get about the same top speed from my LiPo as I do from my Li-Ion. It's admittedly a very unscientific test with many variables but flying wide open in angle mode at a constant altitude, I can only achieve about 56mph from my 7" be it LiPo or Li-Ion. I do see a bit better punch with the LiPo. It seems to get to max speed more quickly than the Li-Ion, but it's not as noticeable as I thought it would be. Thanks again for interesting, informative, and entertaining content. Happy flying amigo. 🍻

[@colibrifpv]

Thanks for sharing your experience, I'm surprised you're getting similar top speeds with both battery chemistries. Your li-ion is going to be much happier, and last longer, without being pushed to discharge too many amps, though 😉 I have both of those CNHL battery sizes, super useful and the price is right! The next time you're shopping for batteries consider buying them in pairs and picking up a parallel cable, your 7inch will handle the weight of a 2600 or 3000 equivalent mah pack no problem, might even do better in the wind, and you'll get some long flight times. Just beware of running lipos too low, when it comes to flying long-range, li-ion is so much more reliable when you're far out because you can fly them down so much lower if you have to in order to get home..

[@Sonic_Ox]

Thanks for the advice and reply! You're spot on. Happy flying amigo. 🍻

Fantastic video & info as IAM building my first 7" long range, best wishes from across the pond here in England ❤

[@colibrifpv]

Great I'm so glad it was helpful! Have fun with that build, take your time and enjoy the process, install a GPS and test it thoroughly in a safe place before heading out for real long range flight. Best wishes from the Ecuadorian Andes 😊

[@Allinfilmmaker]

Range test with the new antennas would be amazing :)

[@colibrifpv]

Thanks a lot for your feedback, I really appreciate it and I will add that to an upcoming video!

[@acar3615]

The TSA guy didn't check labels. However he did swab ever single one, which took forever.

[@colibrifpv]

Right, I've been there before! 😂

[@AngelanthonetAnthoneEsperanza]

And show us as well the under 100 hours you are mentioned. Regarding the battery liteum

[@colibrifpv]

Hey there! The what hours is a measurement of battery capacity, or how big the batteries are. You can think of it like how big your gas tank is in a car. The airlines have a rule that lipo batteries have to be under 100 what hours in order to fly without special permission. The 6s 3000mah pack in under the limit, but the 6000mah pack is over 👍

[@Andrew_Dai]

I am a new baby pilot for fpv, and I got 660&750&1300 lipo. 3000 on livion. Maybe I should storage 660-750 on fly test, and choose 1300 in mid range and 3000 on long range. Thanks for your video

[@colibrifpv]

Those numbers sound right but I need to know what you're flying to be sure. Is it a 5" or a 7"? At the end of the day it's a compromise between performance, efficiency, and weight, i.e., whether you want to "spend" your weight allowance on a heavier but more durable quad, a GoPro, or a large battery...too much weight makes the quad less efficient and it won't fly great, so there is always a trade-off or a sweet spot! What are you flying?

[@Andrew_Dai]

my target is quite clean on the beginning. I prefer to enjoy the flight with a light weight drone. So I practice few month with avata and then choose a 4inch DC frame drone without extra camera. mid range, ocean view and few mountain flight. pretty like to enjoy the feeling in the sky. @@colibrifpv

[@alejandrobez]

Thanks man! 🫡

[@colibrifpv]

I'm really glad you found this useful, thanks a lot for watching!

[@dronepilot260rc]

Nice video! I thought about building a cruiser drone like this but I have the DJI FPV which does more than enough for me and has reached over 3 miles out.

[@colibrifpv]

Hey thanks for watching! I hear you, if your current equipment does what you need it to, just keep flying it, this hobby is expensive enough without constantly upgrading. Then when/if your DJI FPV breaks or crashes, there will be a whole new generation of gear to consider.... happy flying!

[@gpaull2]

On large scale 3D electric airplanes I also have to use higher pitch/diameter props than people at sea level do. I only prop up to get the same watts as those at sea level get. This gives me similar performance (ie hover pull out) as sea level and I have not found lower flight times compared to sea level. If propping up to only give the same watts as sea level should give the same power usage/flight times as sea level, or am I missing something?

[@colibrifpv]

It's interesting to hear your experience. I honestly cannot say for sure or offer any scientific explanations, but I have always understood that at higher elevations the air is less dense, so with all else being equal, to achieve the same amount of lift/thrust you need to run higher pitch props and therefor you can expect less flight time. I haven't actually tested that hypothesis by flying the exact same setups at different altitudes though...

[@felipepompermayer841]

Im building a ultralight 5" long range drone with 2004 1800kv motors, do you think I could use a 4s Liion battery or should keep using 6s? Thanks a lot and congrats for the amazing content

[@colibrifpv]

Thanks a lot for your feedback! You could use 4s lions for endurance flights but it will be very sluggish with 1800kv motors, especially at the end of the flight when the battery voltage is lower. I would recommend 6s, they will be a little heavy but they should give you some nice long flights times with a more reasonable mount of power. I think my Croc5 was flying for ~17minutes on these 6s 3000mah lion batteries with an 1800kv equivalent (4s motors with motors output limit)...

[@AngelanthonetAnthoneEsperanza]

Show us more battery like you are reviewing. With the best antenna you have experienced

[@colibrifpv]

The best antenna you can get for the DJI O3 are the Lumenier AXII Duality 👉 bit.ly/LumO3 and here is the 6s 3000 mah battery 👉 bit.ly/nav6s

[@--JohnDoe]

Can we use 2 antennas on the 03? Or just 1 dual band antenna?

[@guatemalamini]

You can use 2 antenas left hand polarization but you will sacrifice a bit of signal power, flyfish sells Long range dual band o3 antenna

[@colibrifpv]

A dual band linear antenna designed for the DJI 03 should get you better range, the number I've heard is 40% better. Lumenier makes some great DJI O3 antennas: bit.ly/LumO3

[@guatemalamini]

@@colibrifpv not really.. Its about 1db los wich is nearly nothing, The difference of running LHCP and linear are almost not noticeable, i was able to get 5+ km of good signal coverage with non dual band linear antenna... Is ideal to have linear polarization yes but you wont notice the difference

[@colibrifpv]

Thanks for sharing your experience but I've heard differently, @JoshuaBardwell mentioned in a video that the difference is more like 3db which translates into about 40% more or less difference, but in real word conditions maybe not so much because you are more likely to be using long aftermarket LHCP antennas whereas the original DJI O3 antennas was short and may not always clear the battery/frame. These Lumenier Duality antennas should give you the best of both worlds but I admit I still haven't had a chance to test them out. For what it's worth, running identical goggles/DJI O3 VTX, my Moz7 with top of the line long TrueRC LHCP antennas gets less range than my Mark5 with the original DJIO3 antennas and I can DEFINITELY notice the difference...

[@markwilliams5654]

Why don't you use HV lipos

[@colibrifpv]

I use HV lipos on my micros and you can definitely do that and it will give you a bit more flight time, and you can also buy higher end, lighter lipos than the ones I showed in this video, but li-ion batteries are still going to back a lot more energy for the same amount of weight. Another thing is that even though HV cells of are rated for 4.35V, what I understand is that they will still wear out faster. It's like charing your li-ion packs to 4.1v or 4.2v cell... 4.1 will give you longer battery life, 4.2 will give you a slightly longer flight....

[@fehmi35]

Hey man great video, thanks a lot. I am new at this and I want to ask something if you may. I want to carry 1-3 kg load for a possible good range and I want to know what should I consider to achieve this. What is a good configuration for that ? Should I just build long range ones with 10 inch frames and 900kv motors and Li-ion battery ? If you can help me, I would really appreciate it.

[@colibrifpv]

Hey there, thanks for your feedback, glad to have you here! Yes 10" is a good choice because the, larger props are going to be more efficient, allowing you longer flights and higher payload capacity for larger batteries and heavier things like cameras. GEPRC, Sequre, and many other companies offer affordable 10" prebuilt drones, or better yet you can purchase a frame and build it yourself. Your KV is about right for an efficient 10" build. For batteries I would recommend li-ion, 6s2p, with 21700 cells, which should give you around 8,000 mah. You can purchase the cells and build it yourself if you really know what you're doing or you can just buy one from iFlight or GePRC...

[@fehmi35]

@@colibrifpv Thanks a lot. It was really helpful. I am sure I have a lot to learn from your channel.

[@colibrifpv]

@@fehmi35 Welcome to FPV, it's addictive and loads of fun 😁

[@GrumezaStefan]

But for 7inch long range will be enough the 30amp burst???

[@colibrifpv]

Hi Stefan, yes, this battery is designed use on large, long range quads, but you do need to take a few things into account. First, if you are careful with your throttle you will get better results and your batteries will last longer - these are not lipos so avoid punch outs and aggressive maneuvers : ) Second, you will get best results either with the 6000mah pack or two 3000 run in parallel because these "2p" setups will be dividing the amp draw across two sets of 6s cells (12 cells in total)... more cells to share the amp load for larger quads. Good luck!

[@lokkiez]

whats the maximum speed you can fly with the 6s lion on a 7inch copter?

[@colibrifpv]

Hey there my friend, thanks for watching! I'm sorry to say that I don't actually know that, other than to say that it is "plenty" for the cinematic cruising flights I like to do with my 7". It would be very easy to test just using the speed provided by the GPS and the amp draw to get an idea of speed versus battery limitations, I just haven't done it. If you are concerned with speed, go with a 2p 6s pack so the amp draw is shared across pairs of cells and you will be fine 👍

[@flat-earther]

hi colibri, do you think taxation is theft?

[@demetriusdamarcusbartholom5700]

Im interested to see if these are true li-ions or if theyre li-fp...

[@colibrifpv]

@@demetriusdamarcusbartholom5700 What do you mean, why wouldn't they be "true" lions? You can check the links to the product page, where Lunenier lists the exact specs of the cells used if you have any doubts...

[@Tsukuu_]

gimmee the range test with duality's brother please.

[@colibrifpv]

@@Tsukuu_ Hey there, absolutely, I've already done it, I just have to edit the video. Spoiler, the range is way better with the Dualities, these are basically TrueRC antennas and they are awesome for long-range applications...

[@MrPhilbautista]

Can you dive with lions or is that too much stress for those batteries?

[@colibrifpv]

No, that's not what they are intended for. Technically you could, on a super lightweight and efficient quad, but if you are going to fly aggressively you will get better results with lipos. Lithium-ion batteries are really for long, efficient flights where you trade speed/acrobatics for flight times...

[@MrPhilbautista]

@@colibrifpv Thanks. Not really interested in flips and spins but was really hoping lions would be good enough to pull you out of dives. Better I found out here than in the bottom of some canyon or waterfall.

[@Braincho]

Sorry for off-topic. Help me please with a choice of FPV camera and VTX for a 5" quad(analog). Something decent/good(not the best and most expensive), better than i have(Foxeer XAT600M и Eachine TX526 600mW). Also what antenna and where to buy for goggles. Thanks a lot!!!

[@colibrifpv]

From the info you juts mentioned I'm assuming that you want to stick with analog, right? Just FYI, the DJI googles are on sale right now and you can get the Integra goggles for $350 amzn.to/4bsHkC7 so if you ever want to jump into digital, now is the time! Back to analog... do you use Crossfire? If so, a TBS Sixty9 is a great product with built in GPS/crossfire. If you don't use crossfire, check out the GEPRC Maten VTX... it's $60, but it's about the best analog VTX on the market... bit.ly/Maten

[@vadimus2007]

So you are measuring energy capacity in mAh? 6s vs 4s, seriously?

[@colibrifpv]

I'm demonstrating the concept that you get greater energy capacity vs. weight with li-ion packs than you do with lipos packs, and your comment is mistaken...I am not comparing 4s to 6s, I'm comparing 4s to 4s and 6s to 6s. Were I comparing 4s to 6s I would have done it in watt-hours, and I think I did talk about watt-hours in the context of the rules for taking your flight packs on airplanes. Seriously 😉
