5 inch FPV Battery Testing: Round 1 🛎️ 

Something that is really important for racers is how many abusive cycles a pack can take before it starts being puffy. The tattoo batteries are very sensitive and tend to degrade - while CNHL start with less power but degrade slower. It would be interesting to understand the internals and why some are better than others.

For most people, I think performance after 100 cycles would be more interesting than initial performance.

Nice. I’d love to see you test the GNB 1500mah HV 6S battery. It’s my favourite, looks great and has a nice square cross-sectional form factor.

Great testing Chris!! Love what you do for our hobby buddy! Cheers!

Great video, thank you for putting in the time and effort to show us these comparisons!

More please... MUCH more. 🙂

Perfect timing for this vid. Thanks Chris!

Fantastic testing and comparison, Chris! Thanks a bunch! 😃 Stay safe there with your family! 🖖😊

This really helps thanks a lot Chris!

Thank you for your efforts and sharing

Great work Chris 👏

Lovely test. I would have loved to see the ThunderpowerRC 1100mah 6S battery tested here. Especially consdering it's one of the most expensive but best performing batteries out there. Also the lighest by quite a large margin.

Very interesting test, great job !

great tests, as usual! :)

Good work Chris.

Chris !!! Thanks a lot!!!! You’re the best!!!

Another amazing video

I gave up on Tattu 5.0 batteries. They perform great, but cells kept going dead on them. I had 5 CNHL Blacks and 4 Tattu 5.0 batteries, and I had the CNHLs for like 6 months longer than the Tattus. All 4 Tattus had a cell die. Only 1 of the CNHLs lost a cell. Granted, it's not enough data to get a solid answer, but it was definitely enough to cause me to never buy Tattus again. Given your data, I think I might try TheFPV, and see if they're more durable than Tattus. Thank you so much for doing this video!

Very interesting test!

That was really interesting. I've been running the CNHL Black 1300mah batteries on my 5 inch freestyle quad just because they are on the cheaper side of the price range. I definitely notice the voltage sag towards the end of the pack, but I'm fairly happy with them overall. When I get around to building a 5 inch racing quad I'll probably go for the R line Tattu battery since that's when you really need the extra performance. It would be interesting to see a power per dollar comparison too to see which battery is the best value.

i bought so many drones i don't have money for batteries anymore

I will bet someone actual currency that at some point in the next 24 months, Rosser has CNHL put his name on a label and Rosser will tell you its the best lipo in existence.

Yes. That's why I bought rline 5.0 for freestyle. Thanks Chris 😎

Great job

that was one hell of an intro … you should let your inner mad scientist loose more often!

Why wasn’t GNB part of the comparison? They’re the largest brand of available lipos in the UK

"getting into a thermal runaway which I want to avoid" sounds like you had some... exciting explosive testing while getting this set up 😂

great video- just subbed

Most of the packs available today provide enough amps for freestyle and really what's important is their longevity we need packs that can do at least 200 recharges and still perform. Tattu FunFly are the only ones I've had last over 2 years of abuse.

First build with the cnhl blacks and they was okay, least I thought. Then I got some tattu 5.0 and mannnn not only can you extremely tell the power difference but they are so much smaller and lighter. Not only that but Amazon has the tattu 5.0 1200 on prime deal for $32 bucks.

That intro was fantastic 👌Also, its seriously pathetic that we have to rely on FPV community member testing to obtain accurate data that isn't fake news. Manufacturers: please do better! Thank you Chris for all that you do! Your efforts are much needed and definitely appreciated! 🙏

For me the most important is the price. We normally get quite good deals on CNHL Black's.

Thanks for the testing, would love to see gnb 1100 6s non hv testes.

Killer Test 👍🏻 What will be unknown: how manufacturers will keep the quality. TheFPV, never heard them, also CNHL are alledged for buying random cells and high variance between time of purchase and performance

I have both the cnhl black and tattu r-line. Haven`t really noticed any difference between them with my 3,5 inch cinewhoop as a newbie but there seems to be some.

Great video :) would live to see the cnhl ultra black, I would send you one but I don't have any yet. Happy charging!

Interesting results since in our club we found the opposite, I.e. best overall performance were CNHL black with little puffing and taking lots of abuse, while something like a Tattu was so sensitive that looking at it sideways and taking it anywhere near 3.5v would see it puff up immediately, the worst performer overall was the dogcom and FPV batteries, although not bad as in the true sense of the world, we got significantly less flight time on them than others. So how long until we see an AOS battery? LOL

Interesting Video! It would be nice if you could redo these tests after 20/40 full discharges with each battery, to test their durability. We did something similar this year: We found the Dogcom batteries to be our favorite over tattu, and this was our field testing: Me and my friend each use 12 batteries for our racing training. my friend got dogcom and i tattu's this year. We mixed them up a little at start of the season and found the dogcom to be both more robust in crashes as well as being more consistant with voltagedrops over several charges. We found that after Roughly 20-30 dischages per battery, the Dogcom to start performing better than the Tattus. (a full discharge depending on skill and "time on track" between 1:20 and 3 min). As of now, ALL dogcom batteries perform noticably better than the tattu's, to the point that i will buy a complete new set of dogcom for next year, and my friend will keep his old ones for warmup. The difference is mainly in the voltagedrops that occur during punchouts.

Nicely done. What is next? I seem to use a lot of 4s batteries from 450-800 mah, perhaps some around 1000mah. I like all sorts fo flying, but generally i gear towards freestyle with the occasional cinewhoop flight. I have to imagine that this is a fairly popular range of sizes.

Gods work.... Especially now I'm basically solely sticking with CNHL Blacks lol

One thing I keep in mind when choosing packs is durability, I recently had to replace a lot of packs and ended up buying several different brands. All my packs before were CNHL whites, some of them were 3 years old. They are heavy, they don't perform close to other brands but men, 3 years of abuse is a lot. If I spend double the money on a tattu I need to ask the same durability from them.

Great work! Can you do impedance spectroscopy? Would you mind sharing the data files?

I am more interested in Energy degradation. Brand new batteries can perform well, but cycle through 15-20-30 times, and see which battery holds up better on a long-term

Great video as usual. Could you do some tests with CNHL G+ series batteries too? I have some G+ and Black series cells and in my experience the G+ seems to perform much better.

I wanted to ask, in what units is it correct to measure capacity? A/h or W/h? After all, what is most important to us is the energy stored in the battery; when discharging with a high current, the voltage can immediately drop significantly and multiplying it by voltage we get less power. in general, we are interested in the area of ​​the entire graph, for example, with the voltage results at 50% capacity, it was not indicated in relation to which units it was measured. and is it possible to perform a discharge without relying on current? and discharge power? After all, when the voltage decreases, the drone flies differently. electronic loads allow discharge in different modes (stabilization of current, voltage, power or resistance). Unfortunately, my workload is intended for slightly different tasks and it is not possible to conduct research in this vein, maybe the data will be slightly different, or maybe there is no point in this, but as food for thought it is an interesting option.

Would be interesting to see whats the Absolute Max power or Current they can give you for lets say halve a second. If you Pull them from 100% SOC to lets say 2.5V Or What current is need to make them sag below a usable limit.

Tattu R-Line batteries have always outperformed any brand I have tested. And hold their power for much more cycles out of any other brand. And the R-line have way less voltage sag as well.

Cool! I only buy CNHL because they get me in the air or Tattu because they were top on the line a decade ago when I was into RC buggy’s. Do 4s plz!

1. I wanted to see IR of the packs on a reputable testor (wayne gills) meter (typically at storage 3.85v/cell and 70F temp). 2. Also should show battery temp (and temp rise) after running the packs. 3. A IR camera can show issues with the cells, construction (cell tabs) and soldering of the packs. I really believe your hurting the life cycles taking the batteries that low, especially at high currents. If I am not getting 1000 cycles in my quad I wont buy them packs again. And usually another 1000 to 1200 cycles with that pack in my planes (yes, 2000+ cycles). After 2+ decades of racing on-road RC cars at a top level (4 national championships, and 1 world title), having MFG send you packs (or motors) for testing is prime for sending prime packs/motors that typical users cannot buy, seen this happen all the time. Thanks for sharing!

Great testing methodology, the only thing if time/money provided, would be a larger sample set per battery.

Hey Chris I have a few questions about a frame an a tune or preset it. I really really really could use from advice.

🧔‍♂👍Very interesting and professional test in a yet compact video. Thanks for that. But the results don't surprise me, as I've had exactly these experiences with CNHL-Black and Tattu R-Line over the last few years (felt, not measured). What cannot be assessed in the test is the lifespan and in my opinion Tattu R-Line is very durable, which puts the price into perspective. 🔋🔋🔋

Hi ...do you think that , the battery packs for one time use atcking drone should be different ?

Could you test the new CNHL Ultra Black Series?

I'd love to see some higher-cap packs tested. I fly both the Lumenier N2O Featherlite 1550s and the same spec CNHL Ultra Blacks. I wonder what the difference really is considering they're specced the same but one costs almost twice as much.

Good stuff! I have been buying Tattu and Dogcom MCK since they came out. Never looked at ONBO but now they are on my list. I could really feel what you have presented in the data. We need to get Power Density to be an industry standard for sure!

We will see .....made me laugh 😂😂

Million hudreeeed Seeee !

Thunderpower got left out somehow? Best batteries u can buy

Letting manufacturers send you the batteries isn't the best idea, they will always send you the best batch they could produce

I wish you tested the new CNHL Ultra black packs that just came out:

Please test and also make motors for 8S. Thank you

Should we expect a new version of the AOS 3.5 frame? It flights great but hoping you could shave a few grams so i can match my Babyhawk O3 flight times.

tnx

This grear testing! I think it would be helpful if you could compare the same capacity batteries per video. So all brands at 1400mah. I think when buying a battery most pilota look at a size/capacity and then go from there

Why do the measuremed capacity charts have y=0 in the chart (where its not important), but energy density where y=0 would be relevant as they are relative to each other does not have it I also think a percentage difference in something like energy density would be better than an absolute number

hahaha...that intro got me...i can tell this dude binge waatch some ANIME!!!!

Do you also test 6s HV lipos? I'm very interested what the numbers are for the GAONENG GNB 1300mAh 120C lipos. Of course I would be happy to buy you one.

I have 2 ovonic 1300 6s that both crapped out in around 20 to 30 cycles at most and the 3rd i believe is about to go in 40 cycles or so. I wonder why they failed so badly when so many people have had great luck with the exact battery. 1 suddenly drains at a certain voltage and i mean faaassst and the other dropped cells entirely

I always wonder which batterys decay faster

It will be interesting to make some cycles (maybe 200) and than make same test again. So we can see how batteries perform when they are a bit old.

I was currently mainly using cnhl black due to price but i am reconsidering buying cnhl ministar or rline instead. Thank you for these test, it is really hard to judge which battery is better so I was just choosing the cheapest one from reputable brand.

Wow, I'm super happy for getting all my TheFPV packs now! Great job unmanned tech.

you should try the ovonics pls

One aspect not addressed is durability; my Tattu batteries endure twice as long as a typical CNHL battery.

I wish battery manufacturers would start labeling with the chemistry type. I would buy only pure LCO cathode batteries as they have by far the best power density.

Thanks for your work, but the "Power test" seems a bit confusing. With the methodology given you essentially cannot obtain max current readings from the battery: the batteries will be discharged before you hit 70C discharge rate! In order to get to 150C with 1C/sec you have to start at around 130C instead of actual 15C already. With acceleration of 2C/sec starting current should be around 100C, and with 3C/sec you could start at 70C which is around the highest discharge rate in the provided test. Essentially manufacturers write 150C on a ~1Ah pack claiming numbers of more than 3 KW of power. But in the test we can see a max 1.6KW discharge test which cannot truly evaluate manufacturer's claims. Could you actually perform max current rating test for the batteries? I'm asking not out of nerdery but because my current (pun unintended) project requires battery exploitation nearly at full throttle without caring about its longevity. Your tests could save hundreds of dollars and weeks of time (including delivery) on tests for the project I do understand that you are trying to do the tests that correspond to a typical FPV usecase but RC/makers community is more than that and would highly benefit from the information that you can provide

Which battery manufacturer makes the "the Fpv" battery? GNB?

4S battery Test Please

It would be a good idea to test the burst ratings in Watt. That would take the current flow A and voltage sag V in considerarion. Thanks for testing.

Would be great to see 4s testing in the future

1:00 Speezy Pizza

5 out of 5 of my last r-line 6s packs dropped a cell before 20 cycles. Never buying them again. My gnb packs keep ripping for ages.

Oooo

I would love to see the RCHackers tested because I feel they die VERY FAST after 3.6v/cell.

4s packs please I'm old school 😬

Nooo i can't believe you didn't test a Bonka 180c. They are the absolute sauce especially for racers 🚀

12 gauge wire looks tiny on that test rig 😆

A lot less surprising results than the motor testing - it seems we handled batteries a lot more rational in the community ;) But... are you gonna make your own battery now with 30% more performance? ;D

Chris, you started your wider FPV community presence by testing frames - this day you have your own stable of frames, you tested motors - you have the first Supernova for sale and plans to expand the range. Are you looking into making other FPV components that you subject to testing? ESCs? Batteries?

This information is great for the racers, but I'm just a shit pilot. i personally think dependability and durability are more important to me, i like my zeees from Amazon, cnhl blacks (those only, the yellows and white suck) and the tattu v3. But every time i try a high c battery they fail far to easily for me. I would like to see several cycles of discharging down pretty low like when getting the land now on osd. I've had a couple brand new gnb, full send, and the tattu v5 drop dead before even getting the land now. Maybe you should add an air cylinder to punch the battery while high discharging to simulate getting banged around, 😂 I would also like to see some of the other popular cheap packs like the speedy pizza or whatever... Maybe even the white and yellow cnhl, I'm curious if it was just me that had a bad experience, the yellow just seemed to not have it, the white sagged alot but kept going... Anyhoo just interested in more battery info in this size of batteries, maybe do a series between 4s -8s, I only went to 6s this year after 8 years on 4s and was a little disappointed when switching to 6s, i was expecting more... and now i hear 8s is the rage

Extremely controversial topic here. What about the CNHL ultra Black 150C. I heard they are the literal identical exact same insides as MCK batteries. Can you please debunk this?

Ovonic pls

90c! Less is more depending on who you are....

Now go and run each pack hard for one week and re test them. Because I have had pizza batteries die in 3 weeks of use with no damage externally

Where tf is gnb 😂

I'm cheap and always buying 'TheFPV' batteries. Now I'm a smug 'cheap arse', too boot :)

I just had a brand new first charge CNHL blow up on me last night. first one to let me down but almost burnt my condo down. mfs... I will put a video up IF they don't reply to me fast

ha ha CNHL just hung themselves. I wonder if their "ultra" series are any better.

NO GNBs?!?!?!?!
