- Thank you for watching. If you have any questions about the test feel free to leave them in the comments. If you have either of these batteries, I would love to hear your experience with them.
HRB:
% in usable range: 5800mah/6127mah=.9466x100=94.7%
Hoovo
% in usable range: 4026mah/6349mah=.6341x100=63.4%
*Correction: I was rushing while filming this. The HRB had a total capacity of 6127mah during the test not 6027mah as stated in the video. Both packs exceeded the stated capacity by a similar margin.
I tested a pair that came with Deans and EC5 plugs and both were equal as they should be.

This was an awesome test! Thanks for taking the time to make this vid!! I have some packs that I've always questioned the capacity on.
Thank you for this test! I have a ton of hrb batteries for my RC jets. Make me happy with my purchases. Thanks for your time!!!!!
Awesome reviews Mike. Ive got a couple Amazon special batteries and not all of them were weaker but it was noticeable. Great review bro and I would love to see more of these types of reviews. 🙏🙏
Thank you! More to come!
Thank you so much for the information.
LiPo batteries can actually be discharged all the way down to 3.0V per cell before taking damage. As a matter of fact, every ESC on the market today has a cut-off voltage (LVC) of 3.2V per cell as the default setting.
This is because of the voltage "sag" under load. As you pull power, the voltage does sag down, and then will bounce back/recover a bit after letting off.
If you run your truck down to LVC and then get home and throw your LiPos on the charger, you will find that they are in the range of 3.3-3.4V per cell. This is pretty standard behavior. As the pack got to the end of its charge, you pulled power and the voltage sagged below 3.2V per cell and the truck cut off, but then while heading home the battery pack slowly bounced back a bit from the final load that shut the truck off.
So ya, you absolutely can discharge below 3.6V per cell. At 3.6V per cell you haven't even done a full discharge yet. I recommend discharging 3.3V per cell in future tests. Anything 3.2V and below is considered a danger zone you don't want to get too close to that 3.0V per cell threshold. Meanwhile, 3.4V per cell is considered barely low enough to be considered a full discharge. Therefore, to stay out of the danger zone as well as guarantee a full discharge cycle - split the difference and go to 3.3V per cell.
Thank you for conducting this test for us! I've got 4 hrb 50c 5000mah 6s packs that I've been using for 2 years in my helicopters. They have been great and still consistently low ir ratings. I Just recently got back into cars and am using the hrbs in my outcast and talion. They are starting to get beat up on the outside but performing great. I bash with a buddy running a kraton with 2 lectron pro 3s 5200mah 50c (6s) and literally every single time he gets to lvc, I'm at 3.78 to 3.82v on mine.
You are indeed correct. All batteries are not created equal. I'm sure there are better performing batteries but the hrbs do what they claim and do it at a great price.
Cuantos minutos de vuelo te da la batería ?
Thanks. I appreciate your time.
Any time
Saw your comment about this vid over on JTRC’s channel.
Good shit you got going on here.
Thank you. I was very surprised by this. I hope to get more and run the same test or single d/c at higher rates to see how they do. I'm surprised so many people speak highly of these particular batteries. Perhaps their other ones are better.
@@mzgarage I can’t say that I have experience with a ton of brands, but my current preference is GensAce Bashing Pro’s. I currently have several, but nothing bigger than 8,000mah. All are supposed 100C discharge.
@@zachyurkus I only have Gensacre some packs for my edfs. They are going on 6 years old and have hundreds of cycle but they have performed pretty well over the years. Maybe I will pick up some of their surface packs and give them a try.
@@mzgarage yeah the ones I currently prefer are the new hard packs . I’ve been so happy thus far with the 8,000mAh 3S packs (model/part GEA8K3S100E5) that I am looking at a 6s to try out next.
They are a bit pricey but if you happen to get ahold of one to test I’ll be here watching.
@@zachyurkus Yea they are quite pricey. I see they have a 4s 6800mah, perhaps I will try a pair of those. If you want 6s, why not just use the two 3s?
Thank you for taking the time to do this.
Fyi, the HRB link in the description does not work.
No problem! Sorry about that I will fix it asap.
The link should work now. Did you share a link to what you purchased? I don't see anything.
Looks like they are on sale now for $52
Once this video hits 1,000 views I will purchase another set of batteries to test based on suggestions in the comments!
Wait isn’t the hoovo discharging faster? Isn’t that the point? I’m actually asking, I have found myself completely incapable of understanding, C ratings, I have the Hoovo 10000mAh 120C 4S1P packs for my outcast 8S EXB but they were the first ones I bought so I have nothing to compare it to.
Edit: I paid $320 Canadian for these fkrs
Sorry I missed this comment. They are discharging at the same rate as far as current, what is dropping faster on the Hoovo is the voltage. When it it get closer for the end point 3.6v, you can see the Hoovo slow down discharge current because the charger does not want the voltage to drop below 3.6v. The higher the current draw the more the voltage will drop. A better battery will maintain higher voltage under the same load (current draw) compared to a battery that is not as good. Does that make anymore sense?
Thanks
This video needs way more views. I was searching for a reason why I’m only getting 2500 MAH out of my 5500 MAH HOOVO 4S 120C lipos and this confirms what I suspected…they overrate them!
Based on some charts I’ve found online, 2500 MAH to a full charge from 3.65V would indicate a total capacity under 3000 mAh with 3.65v being 10-15% capacity remaining.
Even if those charts are overly conservative, there is no way these batteries have the capacity they are rated for.
Fortunately I bought two pair so I’m able to string together about 10 to 15 minutes of run time with my heavily modified Kraton 8S. The discharge rate seems sufficient for my MAX5-800kv setup but if I could test it, I’m sure that would be over stated as well.
Sometimes you get what you pay for. Sometimes you get less. Thanks for this video. This is very good info!
I couldn't agree more, but did you watch the entire video? They do have the claimed capacity, but all of the stored energy is at a lower voltage than any other lipo I have seen.
@@mzgarage I had to rewatch. I think I was typing my comment during the end of the video so I missed the part about the hidden mAh’s. I sent their customer service a message last night and they got right back to me saying I should run them down to 3.0-3.2V to use the full capacity. They did specify not to go below 3.0.
I actually read that same recommendation in the documentation that came with the battery but i disregarded it at the time because it went against everything I’ve heard about Lipo’s. They say they will replace any puffed or damaged batteries free of charge (within a certain time period) so it’s not really in their best interest to give advice that will destroy their batteries.
The only thing I can think of is that they are using cheaper or lower quality cells that can still perform at those lower voltages. I’m fine with running them that low as long as it doesn’t damage or reduce the lifespan of the battery. I’m already passed the refund period so I guess I am going to change my LVC and see what happens. I’ll update on what I find.
Yea, it seems like some manufacturers are stating that which does go against everything I have known until now. It doesn't make sense to me. In addition to that, if the batteries are under load the voltage would drop far below that and even a lower LVC of 2.8v would be cutting out. Even when lipos are fully charged the spikes of current drop the voltage down to close to 3.2. If you are running different batteries, it could lead to issues. Either way, to advertise these as "high performance" when rpms are based on voltage, it just seems wrong to me. They don't even hold their voltage well fully charged.
I just got the Kraton 8s last week and want to eventually upgrade the power system. Do you feel like it's worth it? Does it feel a lot different?
@@mzgarage I purchased it as a used but newish roller without electronics so I never tried it with stock electronics.
I have no complaints about the hobbywing MAX5 and 56112 motor except for the lack of telemetry and limited programming options. Even with the programming card, you only have 10 parameters to adjust and only generic values for each with no trending. For instance, LVC just gives you the option of low medium and high and I had to search online to find out which voltage each corresponds to. That’s pretty half a** for 2022.
Performance wise, it’s great. I’ve run it with 34/34 gearing and it rips but would get warm at times on hot days. Currently running 36/33 but 36/35 was the sweet spot with the 800kv imo. I also have heavier than stock tires and an aluminum M2C chassis with a bunch of other heavier than stock parts so mine probably could not have managed well with the stock motor.
Oh yeah, the fan that comes with the max 5 ESC broke just about every time out. I ended up buying a 3-D printed shroud to fit a 40 mm rocket fan on to it which has worked out much better.
If I had to do it over again I would go with a Castle system for the telemetry and programming options. You probably already know this but with the castle link you can access tons of stored data on the ESC about different performance parameters. Not that you need it for a basher but I always found it interesting on other vehicles. I’ve heard great things about the 1100 KV castle motor which is slightly smaller and lighter.
I was just looking up the hrb. They were on sale.
The true c rating would make battery manufacturers angry. 120c is enough amperage to melt an xt90 right off the dang thing. Exocage rc does some excellent real world battery tests. For real check it out
The last battery I bought was a 3s zee 1500 graphine. In a crawler with moderate throttle I make it roughy 2-2.5 miles they also seem to charge to 1700mah instead of the 1500 listed. So far that's the best ive used.
Thanks! I will have to check out their test. The C ratings now days are outrageous, I don't really pay too much attention to them because in my experience I have had lower C rated batteries perform better. I just received a set of CNHL 4s 6600mah 120 packs (video test coming soon) and upon the first cycles on the charger, they do not seem much better than the HRBs when those were new. Both the CNHL pack are having one cell drop off right at the end but this is happening between 3.65-3.6v under a 3C load.
No testing needed. Just get a Wayne Giles ESR meter or an RC3563/YR-1035+. Can't trust the IR readings on your charger but they can give you a rough idea of DCIR
subbed great 👍
Do both packs have a similar number of charge cycles on them? Most packs "break in" and gain capacity after 5-10 cycles, sometimes more.
If your doing more testing give the yowoo graphene 100c a shot (blue wrap on the packs). I have run and do run a lot of hrb packs but have been switching to these and they have performed noticeably better constantly.
The HRB packs had more cycles on them, the Hoovo packs were new with a few cycles on them. I cycled them both at the same rate on the charger before completing the test.
I will check out the Yowoo packs, thanks for the recommendation!
Good video bud. Can u do zee vs hoovos. Those are the top 2 bought on Amazon. I'm a big fan of zee. I agree hoovos are not up to par. They always run out faster and don't seem to have the same power output as zee ..
Yes, they are top on the list. I will be ordering them soon, video should be up in a few weeks. Not sure what capacity I will get, but I will run the test at the same d/c rate.
@@mzgarageHave you done a test with Zeee yet?
Are you planning on testing any other budget lipos? I would love to see the capacity test on zeees and Socokins
Yes, I definitely want to and will do more in the future. If this video gets more views and interest, I will do them sooner than later. I do want to test the Zees and also the SMC line (although not really considered budget).
@@mzgarage I subbed so I'll know the moment you drop any more vids like this. I'm about to make some battery purchases for some new models, I'll look very closely at the HRB's
Appreciated, I want to test the Zees and the SMC. I should get a pain in the next month or so.
I have had good luck with the smaller 2200 shorty 3s Hoovo packs. I just bought 2 5200 4s Hoovo packs for my Xmaxx and I am not getting the run time from them I was expecting. I have some 7000 4s Zee packs on the way and will see if they do better.
Let me know what you think of them!
@@mzgarage Will do later this year. It is still winter up here and -20 F outside right now. I did check them on my Cell Pro Multi 4 charger and they came balanced to within 0.001 v between cells on both of the 7000mah 4s batteries I received. That is the closest I have ever received batteries out of the box.
@@mzgarage I have Zeee 7000 packs now and do not like them after doing about 5 runs with them. The punch doesn't take long to drop off making the performance lackluster. When recharging they use around 3600 to 3700 mah to bring them from 3.5 to 3.8 volts and then only 2400 mah to go from 3.8 up to 4.2. It seems to show most of the energy is at low voltage. My Gens Ace 6800 batteries only take 2400-2500 from 3.5 to 3.8 volts and then from 3.8 to 4.2 takes over 4400 mah. Most of the energy with them is stored at higher power. It also shows when running the batteries in the truck as the Zeee 7000 drop off fast and if you try to use full throttle after about 8 min the ESC will kick in LVC even though they have lots of mah remaining in them. The real C rating of these batteries must be quite low causing the voltage to drop under load. In contrast the Gens Ace batteries hold excellent punch right to pretty much the very end of the run and then they just drop off and the LVC kicks in. When you check the cells the Zeee is over 3.6v at cutoff and the Gens Ace are at 3.5. Speed wise with my XRT yesterday I can hit 52mph on the app with both my Gens Ace 6800 Bashers and my new Turnigy Rapid 6.0 batteries. Both of these batteries run hard right to the end and then drop off to LVC. My Amazon Zee and Hoovo packs run 3 mph slower top speed and the punch drops off way sooner. The new Turnigy Rapid are a fantastic bang for the buck. They perform as well as the Gens Ace albeit with a shorter run time, but at almost 1/3rd the cost. I was really impressed with them. I hope they turn out to be a long lasting pack but time will tell. I am getting about 5400-5500 mah back into the Rapid from 3.5 to 4.2 and over 6800 back into the Gens Ace. For the price I will probably replace my Zeee packs with some Rapid 6.0 packs when they come back into stock. Between all my batteries when recharging from 3.5 ish volts I put just over 4500 mah in the 5200 Hoovos, between 6000-6100 into the Zeee 7000, The Rapid 6.0 take 5500 and the Gens Ace take about 6850 mah. Both the Hoovo and Zeee packs have higher IR than the Rapid and Gens Ace
I absolutely do use them up to 3.2v per cells. My esc's are factory set to 3.0 wich I don't really agree but that make me believe 3.2 should be allright.
A lipo should never go under 3.0v. 3.2v cutoff for a heavy load usage mean it should be totally safe, when you are using it hard, the voltage drop a little lower and go back up when it not under load thus hitting the cutoff a little sooner.
If you are hitting the LVC, what is the resting voltage after they rest for a few minutes or when you start charging them again?
@mzgarage 3.2 LVC with about an hour rest time got it around 3.55, I just checked it. (7.14v on 2s, 3.56 and 3.58 each cells, Using gens ace 2200Mah)
Not that the whole hour was necessary, I just kept playing for 3 packs before going back home.
As I said, I totally don't agree with a LVC of 3.0, that's way too close of catastrophic failure but I believe that according to this, 3.2 should be perfectly safe assuming the packs are healthy
Can you please test ZeeRC packs against the HBRs?
amzn.to/3Y3LXLX ?
Thats odd...i wonder if it was a bad battery...i was gonna get that Hoovo..i do have one of there 6s ones..but the 60c version...and i DO thing c rating is over rated...TO A POINT.
I don't even know if I would call it overrated. It has a discharge curve different than all the other lipos I have ever tested (which is just my own over the years). I would definitely recommend the HRB over these and they are nearly half the price. Like I said in the video, both batteries came in pairs, and I tested them both with the same results down to the +- 20mah.
Oh the HVO is just massively overrated in capacity. As far as C rate they seem fairly similar as right off the bat they stayed fairly close
I need help. I got 2 Hoovo 5200 3s 80c . neither will charge on my idst 608ac . but all other lipos are fine .
Does it give you an error? What voltage are they reading?
This guy is spot on. Hoovo are over stated with their numbers. I have a 6s 6200mah 120c Hoovo and its a big disappointment. Used in my Viper 90 and after 3.5 mins it was diwn to 3.6 volts. It took only 3000+ mah to get back to 4.2v. Viper has less power when compared to my other batteries like Ovonics. Hoovo batteries have hype up figures. A major rip off.
At 7:27 it looks like your let meter on the HRB is reading 219mAh, but you state in the video that it had 5800mA discharged.
I had to restart the discharge because it hit the cap on that size battery. I will increase the cap for the next test or not use a preset.
@@mzgarage Understood. In the end, I think you can't go wrong with HRB. Plus aren't the majority of these batteries made at the same factory? I was looking at a USA company in Culver City called RoarinTop, but they probably rebrand their package the same?
Aren't RCs discharging at 100-150 amps with bursts at 350 amps?
What's with the 17 amp testing?
Yes, that is correct, but I have no feasible way of discharging at that rate.
Please shoot me an email (in the about section of my email). I have a spreadsheet I think you will like where I tested 13 different 3s LIPOs against each other and I have been harping on the same things you have and have the same findings between various LIPOs.
Idk. I love my hrb
So far they have been great!
My name is Billy I'm a 37-year-old quadriplegic and I'm on a fixed income… Naturally like everyone else I seen these Hoover batteries and immediately purchased them because of their advertised "C" ratings & capacity claim at 6200… I was getting 10 to 12 minute run times with my outcast 8S and I have a modest set up with a SPEKTRUM 1100KV motor, and I am disgusted at the price/Claims/shortcomings of this battery… What a waste of my time & money !! Ill Stick with the youme 4S-60c-6500mah or get some CHNL's down the line but I don't have pockets full of money like some of these CZcamsrs, so this especially sucks for me 😢
How do you like th e Spektrum 100kv? I am thinking about upgrading in the spring.
Hoovoo are way inflated. They sent me some and they were more like 4500 instead of 5500
Did you watch the end of the video. I was able to get 6350mah out of the hoovo, but about 30% of it was under 3.6 v
@@mzgarage I figured thats what was up. You can never get it all without hitting lvc. So technically i guess they are 6200
I got 7200 mah 4s 120c hovo and it's real mah was around 4000 and weigh 240 grams less than what the site says
Now that seems like they were labeled wrong, that is just too far off.
@@mzgarage doubt it I been seeing many people have this same issue
The capacity I could see, you have to really run the voltage low to get most od it, but the weight cannot be that far off. That's nuts!
Traxxas takes it down to 3.20 I like to set it at 3.4
What do you mean take it down to 3.2? As in they recommend that or you run them down that low? Or are you talking about a LVC?
@@mzgarage My traxxas Maxx & e revo ESC has the cut off voltage set to 3.2. I don't like that traxxas has it set that low. I don't know how to change the cut off voltage on the traxxas ESC. On my other ESCs have the cut off voltage set to 3.4.
If it was set at 3.4v you may have a lot more cut outs. When the batteries use under high load there is periods when it will drop down to the lows 3s for short burst. This all depends on the vehicle and way it's driven though.
@@mzgarage so I did what you said I set it back down to 3.2 for the cut off. My e revo runs so much better! Thank you.
Awesome! Glad to hear!

ПОЧЕМУ РАЗРЯД ДО 3.6 ВОЛЬТА? ОН ДОЛЖЕН БЫТЬ ДО 3.2 ВОЛЬТА!
It is common for china to over rate their batteries. I ran into this with 18650 cells, none of the 9900 mah are real.
Did you watch the whole video? The capacity was accurate, but they appear to hold much of their power at a lower voltage.
