No one warned me I was going to learn something today!
Nathan stenzel this is becoming a bad habit, i needs my "you're gonna learn something today"
Me too!
+1
I stopped watching immediately because I wanted to learn something
Kwad Daddy 🤣🤣🤣
I used to have 4 maxamps packs. Only 1 of my 4 ever lasted the test of time, I still run it occasionally to this day. I had a 1550 4s lose a cell on the third cycle, and the other 2 died much faster than usual with minimal damage to the pack. However, the one 1300 4s pack that is still going strong was always my best performing pack over my r-lines and black labels. One of the reasons people shell out the money is because maxamps doesn't build the pack until the order is placed.
I used to use MaxAmps in my RC cars back in the day. I'm from the city they are made in. So when I got my mini quad I couldn't find any batteries because everyone was sold out of and 3 calls around 500mah for it so I called up MaxAmps and a week later I went to and picked them up. I used them all last year and loved them they never got hot never puffed up when 3 of my 4 Thrust batteries failed. It my be more expensive but the warranty is great and in my opinion they stand by it.
I was pretty excited to see this test. We ran Maxamps 1600mAh HV 4s for spec racing last year on Thrust-UAV Riot 250R. People really had no care of the battery health and would just push em as hard as they would go. I was amazed on how difficult it was to kill these batteries, even to puff them in regular racing, comparatively was a chore. Been running the 1050mAh 6s pack in the pre season and have been nothing but impressed. Sent 2 packs off for warranty to have a balance lead replaced and a discharge lead replace and it was easy peasy!
I have been using, and loving Max Amps for ten years.. They make my monster truck the fastest it ever was. Whatever it was in is going to be the fastest it ever was.. I just flew my first drone last year, and loving that too!!
Curious , is your secret shopper name Boshua Jardwell?
No it is Bardua Joshwell.
I fly with two guys from Maxamps all the time, both of which are very active in the local FPV scene. We’ve talked a lot about their batteries and why they cost so much. If you need the best, maxamps is it. When I can’t finish a two minute race, I’ll fly maxamps no doubt.
The warranty is really good actually. I had a battery (surface) the dropped a cell and I called them and let them know. They asked for a couple of pic of balance and charge rate I believe. The sent me a brand new replacement! Awesome company, I believe part of that price is for the warranty.
I bought a pair of the MaxAmp HV 1350? Batteries a year or so ago. They are still running strong and alway felt like they had a lot less sag than any other batteries I own. You’ve confirmed my suspicions. Great batteries, but man are they $$$ if you’re just going to destroy them on a racing quad.
I'm glad Bardwell can objectively assess batteries even in the face of his self professed bias. It makes his channel, his word and the hobby in general stronger as a whole.
That was a great intro. Hooked me. Laughed when you said "speechless" after talking about it for 10 mins :)
Cool!! It pains me to spend $30-$35 a battery so this definitely is not for me, but if money wasn't a factor I'd buy them after seeing this. Thanks JB
THX for the come back!
I appreciate the objective/scientific methodology. And I like the mix of content in your videos. thanks again.
One possible justification for the high price might be a longer lifespan/higher number of cycles possible. Could you test this vs. other batteries in terms of how long they last? Thanks.
As close to speechless as I've seen you. Best science happy to be wrong if data shows it. Well said! I didn't know about the secret shopper thing. Really smart, and makes test so much more reliable! Well done as always!
Great video keep up the work! Make sure to keep in mind when you’re buying a Max Amps battery that you’re not just paying for the battery but the warranty too so it does cost less in the end.
Nice job JB I love your work, outstanding!
Ok that's great and all Josh BUT DID I LEARN SOMETHING TODAY???? HOW WILL I KNOW??
Joshua great results but it leaves one important question, what is the C rating on batteries based on? Is this a test you could do?
We have to keep these battery producers honest
Very interesting, thank you for this work. I'd love to know how this info relates to real world flying? How high an Amp draw might we actually pull with these tiny screaming motors? Thanks!
Ok, Joshua, we want to see you do a straight up Envy Astro torture test on this battery. That would be awesome. Great video, very surprising results.
This is the sort of battery sometimes needed for electric ducted fan aeroplanes because they draw a lot of current but tend only to fly for relatively short times. Obviously your measurements of current and duration under load are useful but I would also like to see measurements of Effective Series Resistance (ESR) which would indicate how much of the stored energy is disparate in heat. I use a Wayne Giles ESR meter as well as noting the ESR each time I recharge using my iCharger.
I don't buy very expensive LiPos but like most of my friends (some even fly quads) I buy relatively budget Turnight or Zippys from places like HobbyKing. I have a couple of Turnigy Graphene 2200 3S packs and they measure around 3milliohms/cell. I don't push very hard in the foamies I use them in (40 amps max and that only for a few seconds on a pull up) but I'm more interested in their longevity (ie number of recharge cycles) which is difficult to measure quickly.
Yesterday I flew my quarter scale Percival Mew Gull which weighs around 4kg and is powered by a 6S 40C LiPo pack. I draw a maximum of 65 amps but mostly it's less than 20 amps (I have telemetry on the current) and it's quite aerobatic.
I know you and most of your followers are quad flyers but most of the high capacity LiPos I see intended for quads are low C rating and really directed at endurance rather than speed. So I assume these high C packs are intended for racing but do even quad racers need (or even desire?) 1.5kw. That's more than my 4kg scale model needs :) I suppose it's car/truck racing where these power levels are needed but surely they need endurance, too, which 1.5AH isn't going to provide. So I wonder who these batteries is directed at?
Sorry for the long post but I found your video of interest. I'd like to see your test set up. Thanks.
Straight up thanks for what you do Joshua
Gonna order a couple... got to see if it's as good as 100HV Tattu... no problem paying for quality n performance here ☺️
Power ok, Price hmmm, but what is after 10 flights, 20 flights? i go better with r-line or similar and i know i have full 2 seasons a strong batt without drift, or dying cells. maybee it is a competition race batt for one weekend.
Great video as always.
Would really appreciate if you would test acehe 1300 and 1500 75c and turnigy graphene 1300 65c please
Thank you for your hard work to educate us. I’ve been searching the internet for knowledge on this subject. Although these test are helpful in choosing a brand of battery, I was hoping you had some kind of test to analyze weather a 1300mah or a 1500mah 4s was better for a 5” quad. Maybe a comparison between flight times vs performance. I understand that the higher mah will likely have less sag, but will the extra weight cancel out extra flight time? Will the 1500 fly longer cause it can handle more “pulses “ or will it’s heavier weight cause more amp draw and therefore perform similar to a 1300. Or perhaps a 1300 will last longer?
Of course the results could vary from brand to brand battery to battery.
Sorry for the rant, I know it’s and old video but I’m about to buy a hole fleet of batteries and don’t know which to choose.
Ps: if you do another test like in the video try the Ovonics. They’re cheap and I’ve seen a few “pro “ pilots use them
Is this a 2p or a 1p 4s ? because apples and oranges ;) discharge curves will vary. Even the price would sugest it's a double-uped 750mAH pack internal.
I'm sure those in competition would love this battery. I really want to give it a go but 65$ is hard to fork out unless they last a bunch of cycles also. Will probably give one a shot one day soon here. Thanks Joshua!
Very nice JB. I like seeing batteries put to the real test on the UberTester.
Maxamps 1800mah 4S 100c Pack is only 165g. I would like to see the flight times on that pack compared to say an rline 4s 95c 1550mah pack that is 192g
Josh - your impressions of who a product is good for would interest me greatly on ALL product reviews. For example, in this case, I think the cost of these would make sense for somebody who is spending hundreds of dollars to travel to races... which is a different cost::performance domain than most of us who are going to noodle around at local fields.
Great Video! Maxamps is the local "secret sauce" battery. It's great to see a good review of them. Keep up the good work, I love watching your videos Josh.
Nice Review, but im confused even after all this, does the battery do what its claiming, my interpretation is it does not. So therefore its overprice marketing bumbo jumbo.
Me personally id buy them but once you factor in conversion rates and postage i can buy 2/3 batteries for that same amount.
You guys are so lucky with the choices you have. Great review and i do love the batteries form factor.
Even just having a page on your website with links to the existing test data sheets you have so far would be useful. It's annoying having to dig through the whole YT playlist to find each datasheet.
It looks like the main issue with "Graphene" packs is that they're heavier (lower energy density, even if higher power density).
Would be interesting to test some of the Turnigy Graphene packs. They used to be very popular at the local races.
This is your thing, man.
Thanks!
If you have not tried one, I would strongly urge you to test a Glacier Ice 1300mah 75c pack. Very impressive for me :) thanks for the testing!
That really looks freaking awesome! Make a test flight, Joshua! Comparing to the best of the other batteries! Let's see the flight times! 😀
So how long would this battery last in a rc car? More then 10minutes, 5minutes! Thinking about grabbing one for speed runs
Thanks Joshua, great testing! You have any idea when you publish the first shoot out? I'm curious about Infinity and Goaneng, which I use.
I’m so curious what the profit margin is on these batteries, could it really be double the cost to make a battery a little better than all the other batteries? I’m thinking if this pack was say 35 instead of 65 I’d buy a dozen of them right now. Makes me wonder if they are greedy or that little bit of extra performance cost that much. Is that is the case that it’s double the cost it’s definitely not worth it. It’s not like it discharged 3000mah at 200 amps
Been flying GNC batteries, they actually do pretty damn well and they are light! That maxx amps is an awesome battery, but at $60 that would be a hard buy, even for one, I can get 4 GNC batteries for one maxx amps.
Just bought two; shall see how they go.
This battery has Joshua stunned. What has max amps done, mix the Incredible Hulk with a Lipo?
Another great video, thanks for doing these.
How do we get to the list of tested batteries on your KnowItAll site? Also, is the 6s 1250 Pulse on the list of batteries to test considering its the hottest thing right now?
speaking of expensive batteries the racetek battery might be one to take a look at. its sold as a silicon graphene 2400mah hv 100c. i picked up a 2 of them and ran them in my quad for a little while and was happy with it. even after pulling 120 amps on my osd the battery still came down cold. the great thing about it is its not very big just a little bit bigger than a normal 1300mah battery.
175 C means that you can discharge the entire battery in 1/175 of an hour or 21 seconds. So if assuming the unlikely possibility that you could discharge 50% of the battery or 1450/2 mAh in 20 seconds the discharge rate would be (1.45 Ah*50%*3600 sec/min /20 sec) 130 amps continuous for 20 seconds!!! It failed to do 100 amps for less than 10 seconds per the video test. But, that discharge rate is still impressive.
As a comparison, a R-Line 95C 6S 1300 mAh battery handled 7 seconds at 100 - 130 amps in an actual drone flight (strapped to a test-stand so amps could be properly measured). The comparable MaxAmp (at that time) a 150C 6S 1600 (so a larger battery) lasted for 6 seconds in the 100-130 amp run.
A good post. Thanks!
Hi there am a new subscriber to ur channel, u do a very good and interesting videos of this real world facts bout using this lipo batteries 🔋, it’s been 2 years now from the time u made this video, so now my question is how did this battery end up performing and how good it did in every aspect and longevity? If u don’t mind me asking u
JB, have you tested the infinity graphene batts yet?? I've got a couple 1300 70c 4s packs and have a 1300 "80c" Force rs edition from infinity. I love those things. There affordable and I know at one time you had recommended the 70c version as a good budget batt. The 80c version was only $2 more at racedayquads and to me I do get a bit more punch on it.
Great review Josh.... Thank's
Hi Joshua,
Could you please add the Turnigy nano-tech 3s 2200 mah 45-90c Lipo battery to you testing list. Many thanks, I look forward to the results.
It's really unlikely that I will test a 3S 2200. That's just not a battery that many people are interested in.
Joshua Bardwell
Okay no problem, thanks for being straight with me. Respect.
Hello. Thank you for all your work. WE learn ALOT from you. I understand how you rate the C on the batteries you test. Can Y ask why dont you test the C rate given from manufactory? I would like to see how long the handle the C they claim.
Thanks again.
Happy flying
Because at the c rate they cksim they don't last 1/2 second.
I’m more informed on li-on. This is impressive to say the least. I wonder if battery mooch on TH-cam has any lipo testing. Maybe have a convo with him. Fantastic guy. Thank you Josh very interesting.
A bit disjointed Josh but interesting. Are we at the point of a new quantum jump in lipos?
So theoretically it can discharge in around 20 seconds. In that case why not use a supercapacitor?
Hi Joshua - are you planning on testing the Infinity RS Force, Race Spec and the GNB 120c? They are great lipo and not too expensive...
Love your videos Josh!
What is the total IR of the pack and the individual cells on Wayne Giles IR meter when the pack has stabilized temp of ~72F? When you count your pulse tests, you need to count the valleys, not the peaks (these are the discharges). At 100 amps, it took 3 pulses, or 70C, maybe you need to short out the battery to get the claimed 175c, then claim the warranty :)
The peaks are what I count because if it doesn't peak, then it failed the last test. I'm not sure that makes sense...
If it goes below 14.0 volts then the test is stopped and there is no subsequent peak. But the test failed because it dropped below 14.0 So if it doesn't have a peak after the valley, then the valley doesn't count.
Can you test the IR as I mentioned above, thanks.
Are you going to test the demonrc lipos? Oscar Liang field tested them lately and was pretty pleased with them. Curious how they fare on the bench.
Maybe I should start testing batteries to the claimed c-rating and then... if they can live up to the c-rating, continue with the kind of testing you did here...
I"m gaining more and more respect for you....science!
i know this has not got anything to do with the video but what piece of gear is the best idea to upgrade first on my drone
I appreciate your LOVE Of science!
How does one test if this lipo can actually discharge at 245 amps?
And is there a point in which a much lower C rated 5S lipo will perform better?
They kick ass in my 1/5th scale truck rigs
the internal resistance seems to be very low for the pack. Around 20mOhm. I can't see a lot of difference in the relaxation time compared to the other batteries you tested. very interesting results.
Where does the battery tester measure the voltage? Normally you would connect some extra leads directly to the cell.
Would be nice to document the testing with some pictures of your measuring setup on the upcoming website.
J Bender
His machine measures at the terminals and not the pack leads, but it has what amounts to lead voltage drop calibration, and 2ga cables.
It will change the results a little, but from our conversion on the topic it seems like he has taken all of this into consideration.
I use the tattu rline 1300 4s 95c, did you do any testing on those? By the way, I like the shirt! I have one too.
Wow I’m surprised about how good the max amps was, yes I would test a couple other max amps just to be sure, great videos and very helpful, maybe one day can you test the turnigy panthers thanks keep up the good work!!
Great video and well explained thanks
I have 2 1850 max amp battery’s going on 4years now they are little over price mine are still going strong
quick question doing all these videos must take all youre time do you actualy have time to fly it must be really time consuming to do what you do
It does take a lot of time but I still manage to fly a few times a week.
This video has M. Night Shyamalan levels of twist to it ... i couldnt be more shocked if we were seeing dead people
Do you have any thoughts on the Tower Hobby Turnigy Graphene battery line and if so what are they? I thought $25 for a 2200 mAh 45C graphene was a good buy, am I wrong?
*Dance the Skies*
It maybe s giid deal but mi way i wouod fly a 45C lipo on a quad.
Sorry, I'm bad.... should have explained... it's for a plane (Zazzy).
I'm curious about small 4s. I can fly a small battery that won't die out
Would be interested what your battery testing machine would say to the "SLS NOC RACE"
@Joshua Bardwell Is there a chance that you´re going to test a FlightOne RevoltOSD FC in the future? Keep up the good work!
simple question when connecting a motor marked reverse , do you need to cross motor leads ?????
All brushless motors can spin either direction. The CW/CCW marking simply indicates which direction the threads go.
I think you're an alright guy. I mean, I'm not not gonna kiss your ass about how you're one of the best friends anyone trying to get into this hobby could ever have or anything, but you're alright.
Is that burst or continuous? As GNB have 120C batteries that claim 240C burst.
Great review.
Im just now finding this video....So, Im in the PNW, and I wanted to grab a few packs while passing through a town just to re-up my battery collection.
called a few places in Spokane, and one of them mentioned MaxAmps was here in town and would be able to put some together.
I called them, and they told me their batteries are "custom ordered" and 4S starts at 75$ a pack. I told the guy to go screw himself and hung up. LMAO.
At that price, I don't care HOW GOOD the battery is. You can get 4 of the 1500 CNHL for that price.
Have you considered doing an abuse test to see which batteries hold up to over discharge or extended periods of not being in storage? It would be cool to know which batteries are more sensitive. I doubt anyone is perfect at not abusing the battery in some way. Like I recently saw on one of your videos. Do you think it is possible to test to see how much damage is done by things like that or is that way too much work and or too difficult to get real world results? Thanks
I have thought about it but I think this would be tougher to do in a rigorous way.
Joshua Bardwell ya that is kind of what I was thinking.
PLEASE TEST LUMENIER GRAPHENE BATTERIES I THINK IT WILL BE FAR SUPERIOR THEN ANYTHING YOUVE TESTED, best batteries I’ve used in 25 years of r/c
I'd love to see how the r-line V2 HV compares to these, looking at the results on lipo bench they smash the v1 batteries. I have one and I can't imagine getting any more performance, they're unreal
Joshua, Please test the Rotor Riot Hypo batteries next. I'm sure they could sent you one or two if you ask them. I'd really like to know how they stack up. Thanks and keep up the good work!
I'm hesitant to test those packs because of my affiliation with Kwad Camp. I wouldn't want it to appear like I was playing favorites.
I know this is an "off" question, but what Microphone are you using? I cannot figure it out! Thanks for your time....
Rode NT-USB.
Oh and I forgot there was another person testing the max amps and his results were much different than yours on that battery, he basically called them crooks and that they were the worst of all the batteries that he tested. So maybe you got a good one, I’m thinking they mix them up send out some good ones with bad ones because if they were all bad no body would buy them at those prices. Anyway good videos and nice to know that max amps can perform very good and are capable
The battery sounds like a real powerhouse. BUT what is it good for? What real world results does this impressive performance get you? This is not to malign the battery, but to point out that the performance of a system is limited by it's weakest point. So the battery pumps out 100A. Will the ESCs handle it? Motors? If you did have a system that handled the current extremely well, what good is 60 seconds if you need a 2 minute qualifying run?
All I can think of right now is that this performance may enable tech that is not possible with other batteries out there. My money is betting that you can't tell the difference between this and other good batteries that you own. Please let us know if you can perceive actual differences in flight and if you can get a friend to connect the batteries to make it a blind test.
Not worth it to me, but on my rigs I can sag a fresh 90C battery in a minute, and bring it down to 13 volts in 1.5 minutes, so, for a single, speed demon run battery, It would be worth it.
Great point. Speed records / runs would be an excellent application for this battery.
Every quad i'v had in the past year and a half has been limited by battery discharge capacity. Even running 2450kv and relatively low-load cyclone 5040 props, I still hit over 100A peak current. With that said, there's no way in hell I'd pay 65USD for a single battery pack, but there's definitely an advantage to be had with something like this, in real life terms.
TBH, the blatantly false advertising pisses me off though. If you have a high performance battery, then let it speak for itself, don't make up bullshit numbers. On cnhl and other cheap packs, I don't particularly care because it's expected from chinese brands. If you expect to be taken seriously as a brand, you can't lie to your customers in a major way.
JB is doing his own amp rating, and know C rating is not Amp rating, there is some math involved, Mah effects C, sometimes higher Amps vs. C, sometimes lower. If you see, everything he has tested is well below their rated C.
Probably top speed runs for world record!!
You crack me up. I love your content and advice. Please keep it up Joshua! Lets see a flight video of MaxAmps!
I have over 200 cycles on my miniquad battery.....I only have one though!!! They're local here and great guys!!! Just tough to justify it in the quad area!!! My 150c is semi noticeable in punch...but I definitely get better run times!!!
McFlyAwayFPV ! Well said, young man! There's definitely a higher density of power. The weight of a 1300mah with the capacity of a 1450. These batteries can really take a beating. They laugh at full throttle like it's a joke.
I will say me coming from the surface RC world from 6 or so years back and the max amps were the batteries to have in brushless setups for cars and trucks. I know i cant afford that since im still getting to this freestyle kwad stuff....
Do you know if Tatto is gonna release a V2 5s battery???? Do you think that tattoo is holding out till the V1 dry up and is the CH 5s worth trying? 4 of them under 100$ 😳
The CNHL 5S 1300mah performs very well in my testing. However, it's also huge, heavy and awkward. Make sure your build can support that battery comfortably.
It will be intresting to see how battery loses her capacity and low temperatures (0C or -5C, -10C)
Maybe you should offer them some network security advice as i'm sure everyone will try and get hold of MaxAmps designs now.
If you want a battery with good discharge get FU-RC Insaneya 1600mAh 4s2p battery for unlimited amp draw and test that. They are made in colaberation with Tattu.
When I go to there web looking 6s 5000mah line, I said holy cow up to $250 , re they battery made out off gold? With $250 in my pocket I can buy 3 awanfi lipo with that money, but people know maxamps is race battery, I am not racer just general bash, but how many people live in these world as a racer, thank you man for the info
You need to test ACEHE FORMULA 4S 95C LIPO BATTERIES PLZ
I just wanna try one.. But at that price I dont think ANYTHING short of 10 min racing times would make it worth it, even the top Racers will probably only get about a couple of those if they're lucky and use them sparingly at best, and I wonder if high voltage technology has anything to do with it if it's more or less a high-voltage battery with a restrictor plate LOL
