I like your testing method! Great job dude. Can’t wait till you get to the budget batts to. Personally I want to see the Turnigy graphene 1500 and the Infinity graphene 1500 and how they stack up. Thanks JB
Nice job and great report. R-Line is our #1 choice at my club and our field experience tends to confirm your elaborate test protocols. I've puffed a few R-Lines racing some F60 Pros full out, before I had connect a current sensor. I look forward to seeing what the Evan Turner "real Life" power cycles look like. Thanks!
dude. THANK YOU for doing what you're doing!! i am new to most of this and have been flying a grand total of a month. i just bought my 2nd quad and am waiting on it to arrive. the darkmax 220mm. i currently own the furibee x215x pro. ( not the s model.). anyway... the info and the way u present the info is VERY EASY to understand and absorb. i sincerely appreciate what u do. please keep the info coming! i will be binge watching the majority of ure videos in the coming few days.
Tattu has so many different types of batteries. Hard to tell what is the chronological order and what is the newest stuff to buy. Some r-line batteries have a 100c rating. I think they are newer than the one you tested. I wish you did an inner-Tattu testing aswell. Keep up the amazing work, sir JB.
Awesome work! Appreciate all the time and effort your investing in this. Look forward to watching more results in the future! Funny I just happened to visit one if the Tattu Facilities in Dublin, CA. In the lobby where I was waiting to pickup my order of batteries and things they had a video showing the intensive production of the batteries. It doesn't surprise me at all of the R-Lines results due to the amazing quality control and production of their batteries.
So happy to see this video test and in just perfect time! I just saw mines Tattus R-Line 1550 are shipped today and its like doubling my joy, since now I have what to watch and to study while waiting them, and it just fills my sails when I see my newbeeness made a good scan of market before making order for pair of new batteries few days ago.. Amazing test!
thank you soo much for the daily uploads man, i really love em!! although i aint got money for patreon, i try and watch all the ads. keep up the awesome work!!!
Although what you say that this results would not represent real world scenarios is surely true, for me at least what we have here is some really reliable data. Even more in comparison to what we are used to get. Congratulations, JB! I'm really thankful for your commitment, and I think most of us who stick to your videos and stay to watch them until the end should really think about becoming a patreon, considering the contribution you deliver to all of us in the hobby.
Think the weight difference between the batteries would link certain conclusions? As a thunder power user, I enjoy the fact that my packs are lighter than most, helps with keeping current draw lower in races in my experience. Excellent testing Josh!
Awesome job Joshua. I loved the thoroughness of your tests in this new methodology. Excellent work. About the only recommendation I would make is that you add the IR of each pack’s cell averages using Wayne Giles IR meter, just for those of us who use that data for pack longevity comparisons. Maybe also the g/watt rating of the pack as well so that weight is factored in too. Excellent work man! Thanks again!
I have tested that meter, and found it to produce inconsistent results because it's impossible to control for all the factors that affect IR. I'm not saying the meter is inaccurate. I'm saying the thing the meter is measuring is really hard to hold consistent.
Just type "180F to C" into google chrome's search bar and it'll instantly tell you the answer without you even having to actually search it. It's a bit of a non-issue.
Cause it is so simple it wouldn't be so hard to add to a PDF and as 40% of JB's viewers are not American it does seem like a thing that should be at least considered.
I'm glad to see some results. After the "best of the best" testing is done I'd love to see some budget batteries tested. I'm sure I'm not the only one who flies for fun and would rather have more good batteries than a few of the best
YES! So excited. I was literally just thinking about how these two batteries compared when I woke up this morning, cuz I'm in desperate need of new packs, and these are at the top of my shopping list if I decide to stay with 4s. It's like you read my freaking mind or something.
Steele is going to love these results!!! Thank you JB for taking the time to do this testing! This was very interesting. Personally I use the R-Line batts because of the said quality and the price is much better than the other premium batts.
I highly suggest factoring weight into the equation. More than C-rating (current/capacity) I (and many racers) care about current/weight, and capacity/weight. It looks like the R-line weights ~20g more, which appears to scale well to it's ~10% higher current ratings and higher capacity. EDIT: I just saw your "Energy Density" line on the word docs, which is interestingly, identical. My interpretation of your (EXCELLENTLY OBTAINED) data, is not that one is a clear winner, but that one simply has more lithium, which gives you a little more capacity, and a bit better current draw ability, at the cost of 20g (and, of course, $$, but that's almost irrelevant to the decision of "which is the best.")
Same. I think the underlying tech is basically the same, so the weight is the determining factor. It'll be interesting to see if this continues to be the case with more battery testing.
If you want to compare energy density you should do it including the weight of the quad. If your pack is half the all up weight a 10% energy increase with 10% more battery weight is actually only a 5% weight increase.
Excellent! I love to see great testing and your reports are a fantastic way to present the results. Thank you for your time in doing this testing. Could you go to a higher voltage sampling rate for the pulse testing? Having just three pulses for the rating threshold with a slower voltage sampling rate (1x per second?) could easily turn a 3-pulse pack into a 2-pulse or 4-pulse pack at a particular discharge rate. With such a short discharge the file size won’t increase much. Just a thought...
Great work, looking forward to the rest of this series. Thank you for doing this kind of methodical testing. You should do at least 3 of each battery to get a better sample. Or maybe buy 2 and also get a few from the manufacturer to compare. They would gladly send them.
Since the Adrenalines are a bit lighter and the R-Lines have a bit more performance, both batteries are showing an energy density of 0.13wH per gram. So does that mean they perform similarly?
Looks good, as long as things stay consistent your tests are good to go. 1C is generally standard for lithium batteries, so excellent there. Going with your own standard is also a great move, this way people won't claim you are wrong because the numbers don't perfectly match those of others.
Pretty hard to complain about your test, what you elected to do and how you did it makes as much sense as what anyone else can come up with. Likely somebody else would have done something different, but also likely the result between these two batteries would be similar. Your testing is appreciated and only helps all of us get smarter on batteries. I look forward to seeing the results of the punishing Evan test when you can get it done.
COULD NOT AGREE MORE!!!! As I've mentioned in other forums, the ThunderPower batteries might be my biggest disappointment yet. Expensive and all 10 that I bought were complete crap and puffing badly. Now on the exact same quad, the Tattu packs are hang'n right in there without a lick of issues. Zero puffing and provide similar flights as ThunderPower but at a much cheaper price.
Fantastic test Joshua! You really nailed it. Please give us Celsius next time and maybe size comparison. I find that the gens ace are often bigger than their competitors, but delivers more and last longer. Super great comparison! Thanks.
Awesome job Joshua! I have been very excited for your battery tests and I think you did great. I as well like the idea of using some of your bb data to simulate freestyle flying on the packs. Also I would love to see the CNHL 1500 mah 100C be tested along with maybe the RR practice battery or another $20-$25 battery. Thanks for all you do
I'll tell you what, without even watching the video, I've had both R-lines and adrenaline's and what I know from first hand use is this: R-line's held up good while they lasted. Provided good sustained power and didn't sag over their life. They lasted about 3 months with moderate usage before puffing, losing voltage quickly, and beginning to get hot while charging. Adrenaline's: still running with no discernable difference in capacity and no noticable sag since I bought them in 2019 (3 years ago), just after the r-lines went bad. They sat for a period of about 10 months while I took a hiatus away from flying after 10 years - some of them fully charged. I have been running them hard for the last month - about 5 packs a day, and they feel like the day I bought them. There is not the slightest hint of puffing in any one of them. It's freaking insane, really... After the last month seeing how they perform at 3 years old, I understand their price and now have absolutely no problem paying for them. I did cringe when I originally bought them. But holy sht are they good batteries. Just did an internal resistance test on a few - not a single one having an IR over 4. It's quite silly actually...
Often Gens Ace manufacturer is the best. It would be nice to have: 1- Internal resistance. The lower it is, the more punch people feel. 2- Energy available in watt hour or joules at different discharge level, you do almost this by giving capacity/discharge rate but it's not the aera under the curve We appreciate your work. Thanks
Fantastic Joshua! Your 5 second burst test is good but it's the extreme. The next part of the story will be interesting - the programmed discharge based on a real but insanely good pilot flight
Hey Josh! I gotta thank you for getting me up and running on my Tiny7. Im more of a 3D plane flyer but, I have been wanting to get into quads as well. Your video/s got me up and running in no time. I have used, and will continue to your sponsored links whenever I buy my FPV gear or any other related RC gear. Always a thumbs up for you man. Thanks for helping a novice drone flyer. :) It took me awhile but you really make it pretty dang clear! #honest And this was a great video btw! Man you just keep getting better and better! Stoked for you living your dream. Must be great having a career that you love so much! Sincerely, Whitney Harding
I like the tests you've implemented, especially the pulse test and I think a second pulse test with shorter pulses (1s on, 2s off for example) would be another good one to add to the list.
First of all: Thanks for the testing! Thats awesome! I am looking forward for the next results. Is it possible that you show us your setup? How you set up/wire up everything... how you meassure the temperature... how you control air temperature etc... I know you mentioned it in a video but it would be awesome if it would be on your website or in a video of yours.
Awesome test's, I love it. Like others have suggested please factor in weight as well. Showing us both the current and capacity vs the weight helps both the racer and recreational flyer. Thank you so much!
Grat testing. Are you testing the Turnigy Graphenes by any chance? Curious as I can't remember where, but I have seen in another test that they perform better (only slightly) than the Tattu R-Lines. Would be very interesting if you come up with similar results.
Awesome test, but in my experience RLine has a poor longevity are great batteries but only for a certain time, curious to see your conclusions. thanks for sharing
As someone who has had both exact batteries long-term, I can confirm the results. Also, the Thunderpowers WILL puff prematurely after a few months of normal freestyle use (not even hard-core racing). R-Line all the way, baby.
The variation in tolerances of SMD components exacerbates the need to calibrate each and every board. We deal with that "problem" in the RF products that my company manufactures every day. A tenth of a pF can throw the product into a tailspin. A tenth the other way and it's sunshine and roses. Don't worry, Joshua, it's an easy assumption to make. :)
I don’t fly droan but I used the same batteries in my mini jet, The r line and tatu are good batteries like you said. I used tatu 1550 75C an R-line 1300mah 95C. What I get from these batteries, unlimited vertical, quick acceleration, 80mph from my mini f 18 blue angels. Is a great battery for all applications
Hi Joshua, great testing. Even though they may not be exactly what you see in the field they give a good relative metric to compare batteries. Are you planning on testing the r-line V2? The reason I ask is the lipo bench website show a 5second burst is the max for the v1 and a 40second burst for the V2. It would be good to see if there really is that much of a difference. Keep up the good work, it's extremely interesting.
I really like that you take payment in the form of crypto. FInd that pretty cool. I love what you are doing for our hobby. I remember watching you years ago when this whole fpv with quads started to be a thing and your video's surfaced. I questioned you in the beginning and now look at you. Goes to show that hard work/love/ and dedication really pays off. Grats.
What a way Josh, I learnt something today. I was thinking with some high amp solid state relays, a microcontroller and bit of code you could automate your testing methods. Let me know if you need a hand.
Great stuff. Can you please test the Turnigy Graphenes? The higher C rated ones seem to hold up better than I would expect but I fly freestyle so maybe I just don't put that much stress on them.
I'm a new to hobby and chose my first two batteries that fit my budget, Nitro Nectar 4S 1300mah 80C packs. I choose these because the heat results from another TH-camr had these at 111 degrees vs much hotter temps with others. Does a battery that produces a lower heat automatically mean its a good buy and will last long? Is heat a major factor in a battery purchase?
That's awesome Joshua well done. It would be great to see how maybe something like the DINOGY 1600mah graphene battery in the orange package wrap performs against a non graphene battery, ie compared to the results of the Tattu Rline. Are they any better or worse? and is there really any benefit of getting a graphene battery? Thanks mate.
Fantastic!!! Thank you so much. Really looking forward to the "real flight" test. To bad the data was clipped :/ How did you extract only the current draw?
Awesome test. By far the most comprehensive method I’ve seen so far. Can you test CNHL and Infinity at some point. Also I’m very interested to see how Venom stack up. My experience has been that Venom are the most expensive battery I’ve purchased and have given the least performance. I just can’t understand why Stinger Swarm uses them
I love your test, since I have no other fpv buddies it's hard for me to judge what batteries I should go with down the road, is there any chance you might do a more budget friendly battery test like the 20-25$ range? Also how about testing some of those rotor riot batteries? They seem pretty pricey. Keep up the great work brother
Awesome video! I kinda think that a straight 5 second burst on pulse testing is too long to be a real world approach on the batteries. I mean who goes flat out for 5 seconds then stops for 5? I think 3-4 seconds would give more realistic results for this aspect of testing. 20-30% reduction. So awesome the tests are coming out tho! Thanks for all ur hard work JB
I'm sure you are getting bombarded with questions and recommendations about this... Can you do 5s and 6s testing as well? I don't expect you to prioritize that over 4s, since that is what has been the standard for so long, but so many people are moving to higher voltages, and I am really curious to see some of the differences, and which packs are recommended when you start looking at 5s or 6s packs. Thanks!
I like your testing method! Great job dude. Can’t wait till you get to the budget batts to. Personally I want to see the Turnigy graphene 1500 and the Infinity graphene 1500 and how they stack up. Thanks JB

Joshua thanks for what you do. Your such a dynamic speaker and likeable person that I feel you’d succeed in anything you do.
Youve done "top end" now lets see budget (and everything inbetween after!) Great tests. Love the vids, cany wait to see how they fair in the race sims
Great testing Joshua !!! This is why I Patreon support your efforts. Not one other You Tuber does this much real science.Keep up the great work !!

Excellent testing Josh!
Awesome tests, Joshua! Try getting some Gaoneng to test too. 😊
Second that. Especially a 1300mah one
Tapwoot nothing special. I own tattus and gaoengs and the tattus are waaaaaay superior!!!!
Yes, but the price is double. I factor that in to :)
Joe Gonzales If the Gaoneng is good enough, close enough to the Tattu ones... Great! Like Tapwoot said, there're cheaper! 😊
Michael Benjamin GNB beats the Tattu in tests. MuteFPV tested them, the results show exactly the same as your feeling.
Awesome job Joshua. I loved the thoroughness of your tests in this new methodology. Excellent work.

Plenty of information including a super detailed spred, I found this review very interesting cheers JB.
Thanks for doing a battery segment. Im on my first build and you helped open my eyes to better understand. So thanx
Thanks for running these tests. Finally some real data on batteries!
Good job JB I use the r lines and I’m happy to see I haven’t been wasting my money
Can you put Celsius on at least on the PDFs? So non-Americans don't have to pull out a calculator.
Just type "180F to C" into google chrome's search bar and it'll instantly tell you the answer without you even having to actually search it. It's a bit of a non-issue.

Sweet testing and data! Bummer about Evan's test replay, but you guys will get it worked out. This is going to be a fun year of battery data!
Thank you Joshua, looking forward to all these tests!
Yay! Love the standards and testing protocols you are using!
Kick ass Josh! Thanks for doing this set up and test. I personally very much appreciate it.
I'd like to see the CNHL batteries from RDQ on here.
This was fantastic! Really looking forward to the rest of the tests.
Thank you for putting so much effort in these tests to make this hobby better. :-)
Nice job Josh, it will be really nice to have a bunch of batteries tested the same way to compare stats.
Great review. I've got 4 packs of the R-lines, and 10 packs of the new R-line v2....glad I made the decision to "invest" in top end batteries now
I'm glad to see some results. After the "best of the best" testing is done I'd love to see some budget batteries tested. I'm sure I'm not the only one who flies for fun and would rather have more good batteries than a few of the best

Yup that data is in the PDF which you can assess for yourself.
Brian Bailey ha ha, you come in like a whiney bitch. Just make your point, not like a lickle bitch
Just..Wow.. The internet is a terrifying place when a guy can make a polite, reasonable point and get called "a bitch".
If you want to compare energy density you should do it including the weight of the quad. If your pack is half the all up weight a 10% energy increase with 10% more battery weight is actually only a 5% weight increase.
Excellent! I love to see great testing and your reports are a fantastic way to present the results. Thank you for your time in doing this testing.
Could you go to a higher voltage sampling rate for the pulse testing? Having just three pulses for the rating threshold with a slower voltage sampling rate (1x per second?) could easily turn a 3-pulse pack into a 2-pulse or 4-pulse pack at a particular discharge rate. With such a short discharge the file size won’t increase much. Just a thought...
I agree. I have switched to 100 ms sampling for future tests.
Great work, looking forward to the rest of this series. Thank you for doing this kind of methodical testing. You should do at least 3 of each battery to get a better sample. Or maybe buy 2 and also get a few from the manufacturer to compare. They would gladly send them.

Excellent! I'm happy! Happy flying! :)
Brilliant, proper engineering! Thank you, really looking forward to the longevity tests and flight profile comparisons 💪🤘👌👍👍👍
AceHe 75C & 90C lipo test would be epic! Best batteries I’ve ever flown.
I like the tests you've implemented, especially the pulse test and I think a second pulse test with shorter pulses (1s on, 2s off for example) would be another good one to add to the list.
Awesome job. It was clear and it felt like indisputable data from what I seen.
First of all:
Thanks for the testing! Thats awesome! I am looking forward for the next results.

how you meassure the temperature...
how you control air temperature etc...

The variation in tolerances of SMD components exacerbates the need to calibrate each and every board. We deal with that "problem" in the RF products that my company manufactures every day. A tenth of a pF can throw the product into a tailspin. A tenth the other way and it's sunshine and roses. Don't worry, Joshua, it's an easy assumption to make. :)
Looking forward to the testing with real world amp data. That will be something we haven’t seen before and will be very useful
Awesome results video Joshua! I'd love to see some Acehe battery tests!
I don’t fly droan but I used the same batteries in my mini jet, The r line and tatu are good batteries like you said. I used tatu 1550 75C an R-line 1300mah 95C. What I get from these batteries, unlimited vertical, quick acceleration, 80mph from my mini f 18 blue angels. Is a great battery for all applications
Great vid! Sounds like im holding off a bit to buy new pairs of batts before I see some more testing!
Hi Joshua, great testing. Even though they may not be exactly what you see in the field they give a good relative metric to compare batteries. Are you planning on testing the r-line V2? The reason I ask is the lipo bench website show a 5second burst is the max for the v1 and a 40second burst for the V2. It would be good to see if there really is that much of a difference. Keep up the good work, it's extremely interesting.
I really like that you take payment in the form of crypto. FInd that pretty cool. I love what you are doing for our hobby. I remember watching you years ago when this whole fpv with quads started to be a thing and your video's surfaced. I questioned you in the beginning and now look at you. Goes to show that hard work/love/ and dedication really pays off. Grats.
Hey do you think there is a noticeable difference between 95C and 120C? Or should you save the extra money?
What a way Josh, I learnt something today.
I was thinking with some high amp solid state relays, a microcontroller and bit of code you could automate your testing methods. Let me know if you need a hand.
Very interesting. You don't always get what you pay for. Another awesome video with a ton of information
Excellent job Joshua, would be interested to see as you go forward if there is a correlation between battery capacity and weight ?
Definitely in general although higher quality cells do better per gram. That's the purpose of the Wh/g stat in the PDF.
Great stuff. Can you please test the Turnigy Graphenes? The higher C rated ones seem to hold up better than I would expect but I fly freestyle so maybe I just don't put that much stress on them.
Nice testing. Any comparable internal resistance values? Can the IR predict the performance of the battery?
I'm a new to hobby and chose my first two batteries that fit my budget, Nitro Nectar 4S 1300mah 80C packs. I choose these because the heat results from another TH-camr had these at 111 degrees vs much hotter temps with others. Does a battery that produces a lower heat automatically mean its a good buy and will last long? Is heat a major factor in a battery purchase?
you are awesome! i learned so much from you thank you
Cool testing, great stuff🤙🏻
Excellent and informative. Thank you...
tattu R ! buying some now thanks josh!
That's awesome Joshua well done. It would be great to see how maybe something like the DINOGY 1600mah graphene battery in the orange package wrap performs against a non graphene battery, ie compared to the results of the Tattu Rline. Are they any better or worse? and is there really any benefit of getting a graphene battery? Thanks mate.
Fantastic!!! Thank you so much. Really looking forward to the "real flight" test. To bad the data was clipped :/ How did you extract only the current draw?
I extracted it to a CSV file with blackbox_decode.exe.
Awesome test. By far the most comprehensive method I’ve seen so far. Can you test CNHL and Infinity at some point. Also I’m very interested to see how Venom stack up. My experience has been that Venom are the most expensive battery I’ve purchased and have given the least performance. I just can’t understand why Stinger Swarm uses them
I love your test, since I have no other fpv buddies it's hard for me to judge what batteries I should go with down the road, is there any chance you might do a more budget friendly battery test like the 20-25$ range? Also how about testing some of those rotor riot batteries? They seem pretty pricey. Keep up the great work brother
Nice to see some clear results, great piece of work.
Will you be doing any vids on the micro crossfire unit in the near future?
Yes
Joshua Bardwell
Fantastic. Many thanks.
Since we all fly different sizes of quads, I hope you'll test everything from 2S to 6S batteries, so we can buy the best performance for the money.
Thanks for your work man!
Awesome video! Are you going to test 6s batteries?
Awesome video! I kinda think that a straight 5 second burst on pulse testing is too long to be a real world approach on the batteries. I mean who goes flat out for 5 seconds then stops for 5? I think 3-4 seconds would give more realistic results for this aspect of testing. 20-30% reduction.
So awesome the tests are coming out tho! Thanks for all ur hard work JB
Great job. Is the second test out yet?
I'm sure you are getting bombarded with questions and recommendations about this... Can you do 5s and 6s testing as well? I don't expect you to prioritize that over 4s, since that is what has been the standard for so long, but so many people are moving to higher voltages, and I am really curious to see some of the differences, and which packs are recommended when you start looking at 5s or 6s packs. Thanks!
