Listening to pilots argue about batteries based on personal experience is like listening to a bunch of truck bros at an small town bar argue Ford vs Chevy vs Dodge.
Those pilots are no doubt considering a lot more data points than this test provides. Every battery feels pretty good when new, but what happens after 50 cycles, a few over-discharges, etc.
One thing I noted with the R-line 550s is they can be charged to 4.35 per cell without noticeable degradation. Discovered this by abusing 10 or so packs thinking they're HV like the rest of my R-lines, and charged them in parallel and one at a time this way for over 6 months.
With every video your editing and pacing get better and better. You were FLYING in this one yet all the information was still easily digestible. You're kickin' ass! Keep it up!
This. I bought some of the Tattu 6S 550 packs from Amazon (I know, but it was a good deal on Black Friday) for my AOS 3.5 (love it!). I got IRs on first charge between 20-30 m-ohms per cell, and wrote to Tattu asking if this was normal, which of course they assured me it was. I understand that smaller cells mean higher IRs, but how high? Is it OK that are some cells in the same pack are starting out at 22 and others at 30?
I have the cnhl ministar 650mah 4s lipos for my sub250, and it seems they placed in the middle for pretty much all the tests. They may not be the best or worst, but they are dirt cheap and perform great for casual freestyle. I can get them for about £9 per pack or even cheaper when they go on sale.
CNHL are currently running a sale on their online shop. I just bought some 650mah 4s for less than €7.50 each from their EU stock, despite watching this video. I can't justify paying triple the price just to get a bit more power when I only do freestyle.
What a nice timing I am right now in the build of a sub250gr 4s 4.5" quad. I have already 4s550mah tattus with which i'm happy on 2.5" 4s naked gopro cinewhoops. Most probably the 750 will be already to heavy on that 4.5" but i'd loved to use them, too. So good to know they are somewhat the better option. Liked as always the video and thanks a lot for your work!
Bought some Tattu 550 4s batteries for my cinewhoop build trying to transition into pro not long ago, glad to see test data confirmes my feeling that they were performing well lol
Thank you, great testing Chris. Displaying a scatter chart of C-rating vs. Power-density (W/g) as a combined comparison could make for an interesting summary. Including measurements of internal resistance when charged, and discharged could also be interesting, but this would require special equipment to get good results (uses high frequency AC). Generally is low, but increases significantly for weaker cells as they discharge. (this is an indicator of heat being generated, or unusable capacity)
Of course there are limitations of testing. But note that 4S 850 mAh can also be considered sub250. The 3.5" EMAX Babyhawk O3 Air Unit is with a 4S 850 mAh lipo at 248 grams.
Again, you not show one of the two most important parameters. ESR in milliOhms per cell and total pack including wire and connector? This will give a exact number to compare esr numbers. Remember to have the battery at 3.85v storage voltage and the same temperature. Get this one "Lipo ESR Meter Mark II "
I wonder why no HV. I cant see any reason why the GNB 850 4S (purple one) wouldnt outperform any of the batteries listed esp when you consider it weight at 71g. With the 750Mah Tattu at 85g my explorer would be 15g overweight.
In my experience the Tattu's are light, very expensive and are great initially but after a bit of use, puff & fall off the cliff. The CNHL are cheap, heavy, mediocre performers, however don't puff and eventually out perform my Tattu batteries. It's never clear cut.
For my 3S-gang: exactly what I saw with these batteries’ 3s brothers. I saw in 6s that Tattu was really the best and wanted to stick to the brand despite the price, but recently tried and liked Dogcom (MCK Ed.). So I tried the 3s 560 Dogcom as well and there is no difference in flight feel, time, max Amps and voltage drop when compared to the 550 r-line. Both however beat the 650 non r line tattu in all regards as well as the GNB up to 720mAh and obviously any 380 and the too heavy Tattu 850 (flying Baby Ape pro V2, with and without upgraded Motors) And when I asked other pilots about the Ministars their answers where all over the place and I guess that is exactly what we see.
from my experience I have only used R-lines and GNBs in 3s and the Rline blew the GNB away, on baby ape 2 non pro analog and a 533 trainer hdz (90s fps is crazy). I have a crux35 with the 1w hdzero on the way
Why do you discharge with C rating current instead of one (or multiple) constant currents (eg. 10, 20, 50 A). This way it introduces manufacturer bias (eg. label battery with lower mAh and come out as voltage sag king).
Interesting, gotta check out those dogcom it seems. Gotta ask, did you only test one of each battery and only once? or was there more than one test of each battery, and was there more than one of each battery? i would also be interested how different batteries would handle cold. anyways, thanks for the video :D
I was just looking for this video yesterday thanks! I hope to see more testing on 850mah (90g) batteries. What are your thoughts on the 4.35V HV batteries? Are they hype, or are they really delivering better energy density? Does the extra voltage damage the battery after cycles? Is the drop-off in performance comparable to 4.2 volt batteries after many cycles? How does the cell capacity handle abuse after a punch to 3v?
Ive had around 20 cnhl. All have been junk. Sag terribly on high powered quads. Tattu dont last but have excellent power. My favourite bang for buck are ovonic.
Why no GNB batteries? Why no 1000 or 1100 batteries? For reference, I fly the GNB 3S 1100 65C batteries in most of my quads from 2.5" through 4". I have gotten over 15 minutes using this battery on a stock 2.5" GEPRC Phantom. Yeah, I am an endurance pilot and I don't fly stunts. Still, your video is about batteries rather than type of flights.
50% meiner 650er und 800er CNHL haben Drift, oder knicken massiv ein. Bestell jetzt wieder sls xtron und tattu. hab echt die schnauze voll von den Angeboten... bringt ja nix.
Forget all these random cheap shitty lipo lets see a comparison between the top tier which all fpv pilots already know is dogcom, bonka, tattu. just put in anything rated to 150c and higher, also would be useful to see how they perform before and after 20 high amp discharge cycles.

I can't believe you didn't test the gnb 720hv, fantastic sub250 4s battery
long range battery

Nice test but I really hoped to see GNB / GepRC LIHV ones, very used because of the reduced weight around 60g for 650/660mah
I would also measure internal resistance which is an important parameter in judging battery quality and impacts heavily on voltage sag and performance

Thank you again for doing these videos! I really like the unbiased science behind what makes these packs good!
Really appreciate this Chris. Just got a sub 250g and had no knowledge about this size of battery
Pleased to see that you also tested the SLS lipos! All your tests were well explained and easy to follow, love your videos!

GNB 720 4s hv 100c pack is my favorite
Fantastic test. Concise, insightful and clear. Great job sir!

I have some CNHL 3S and 4S packs and they seem to hold up quite nicely over time. Degradation is not much, so quite happy about them.
thx!
i guess you can scale the results to 2s or 3s with the same mah and c rating
Of course there are limitations of testing. But note that 4S 850 mAh can also be considered sub250. The 3.5" EMAX Babyhawk O3 Air Unit is with a 4S 850 mAh lipo at 248 grams.
Thanks for all the testing and comparison, Chris! 😊
Happy new year! And stay safe there with your family! 🖖😊
Awesome!! Love seeing the data! Thank you!
Hey Chris , Where would the GNB 650mAh 240c 4s fit in the chart?
Why no GNB HV? They are awesome from my experience. Better then dogcom, for example, especially considering price. Half the price.
Again, you not show one of the two most important parameters.
ESR in milliOhms per cell and total pack including wire and connector? This will give a exact number to compare esr numbers. Remember to have the battery at 3.85v storage voltage and the same temperature.

No GNB?
I use axis flying 1500 4s hvlipos for my 3/3.5/4

i would also be interested how different batteries would handle cold.
anyways, thanks for the video :D
I wonder why Ovonic batteries never show up in your tests? I am a fan of the 650mah 4s LiPo which is very light and power dense I believe..
this is exactly what i also want to know, they live extremely long too
Good to know 👍🏽

Hi Chris, would you use a 1505 motor 3450kv motor 4s battery on an Axis Manta 3.6 with a naked GoPro?
While my Ovionics 4S 650 are only 80C they're also about half the weight weighing 54g compared to the Dogcom
which ones? I see 70g in the specs, 3s are 54g
Good test and comparison video
When AOS T3 V5
i love rlines
Another great video 🙂
Ovonic ?
Awesome!

Love you
WE NEED SUB 80g pack's mostly 3S (who agrees comment and like the comment)
My tattu batteries all inflated. CNHL and other still in original shape.
nice!!

Conforming to 250g is very stupid. The "law" is not enforced 99% of the time.
True, but lighter quads do perform better, so there is merit to this.
If you’re willing to risk a very heavy fine for that 1% I guess..
and how many people fly after having a few beers *cough*
1% enforcement seems monstrously too high. When has it ever been enforced?
Chris, what motor would you recomend for your aos 4 frame, with gemfan 4023 props?
