Great video! Thanks for spotlighting the Zee battery line as there are many rc enthusiast that run these batteries in their rigs. There’s another list that has been compiled including all lipo batteries on the market today and Zee batteries tested very low. Don’t fall for the 100c rating cause all brands are not equal. The Zee 7200 mah batteries (hard case) are very good batteries.
Thanks for the comment!
Where would one find this list?
I’d love to see the comparison to guide my future purchases.
Nice charger do you have a link for that?
It's a Polaron EX1400
What about "Redline" Gens Aces? Is the best which i can buy in the middle of the Europe. Have you some experience with this brand? Overall they seems to me like solid batteries. I have 6000mAh short pack and some 5000-6000 standard hard packed 2S. For small 1/10 im using one short or one long, depend on the truck. On 1/8 buggy i have two long connected into series. I not measured a resistance yet.
Hey Martin, I don't have any experience with these. They do look like good packs. If you do measure resistance and have capacity I'm interested in your findings.
@@RCexplained Gens Ace standard 2S hard pack 5300mAh. 5 and 6m Ohm (batt has 50C in spec) and has only few cycles. Old Gens Ace short pack 6000mAh 120C rated - 7 and 8m Ohms. Batt is 2 years old bought from second hand. Seems to me not bad. But as i said, bullets batteries has higher resistance. Some another brand with a 4mm bullets - 7500mAh had 4 and 5m Ohms as a new. New gens ace with cable and connectors had 1-2m Ohms. Really depend not only on manufacturer.
Think these will still we good for bashing, how much does this change the run time vs just power they provide?
I would not even use them for bashing but I'm sure there are a lot of people that would. While bashing my vehicles with enter LVC after 3800mAh was pulled.
I built a 1/10 Xray truggy and I’ve had nothing but issues. If it wasn’t overheating it was devouring the battery. It is my fault for using a 4.5t mod motor and overgearing it a bit. I finally settled on a 16t pinion and it’s not as fast as I was hoping it would be. If I go any higher it overheats. 18t does ok as long as it’s not too hot outside.
I’m using a 4200mah reedy 2s pack. At full charge I can do one full power 0-132 foot run. On the way back it’s in limp mode from the voltage drop. The stadium truck it came out of could do pass after pass on a 5.5t mod motor and way higher gearing. Hopefully a better battery will fix it.
@fly2kill1 I have the same problem did a better battery make it any better?
@@craigoliver2810 no. I just had to gear down. I’m waiting on a 6.5t for it.
nice video man, what do you think about the zeee 3s 2200 mah 120 c?
120 c out of such a small Pack is ridiculous! Not believable at all.
You need a somewhat big pack to sustain such current. 120c means you could draw 2.2Ax120c=264A.
264Amps is downright ridiculous.
If they would say 20-25c that would be probably right.
Ever wonder why traxxas batteries are so conservative with their c ratings?
Not saying they are good, because they are mediocre at best. But at least they don't overpromise with their ratings.
@@AsurasWrath164 the best batteries in the world maybe MAYBE output 40C for the top 30% of charge. Most batteries are 15c-25c. Your 2200mah are probably about 30A-35A batteries.
I have not tried these.
@@RCexplained ok thanks 👍🏻
Can the sidewinder 3 handle this battery?
No. Esc says 3s max. This battery is 4s
I race using almost exclusively zeee batteries for ebuggy. An starter box, venom an gens ace battery for nitros. But ebug batts are the red label shortys 7.6v packs
Do your packs perform better than the results I got?
Well, i run at outdoor at my local track at phil hurd Raceway. But i use idst charger an dischargers ,an thats what i get my ir . And I've came out with long-term much better results than what you have. But I'm not doing speed speed runs so I don't know mathematically what makes the difference. But they've been dependable and great. My opinion so I had therefore don't think they suck at all!!🦀🦀🦀
How are those treating you? Im looking at them for 17.5t 2wd too
I recently bought 2 Yoowoo Graphene 5000mAh 100c (6s) packs. They do quite fine for me, but I wonder how they compare to other packs rated around 100c. Could you do a calulation/comparison? Thx for your video's 👍
Thanks for the comment. I'd love to test all the batteries I can, problem is, it will become quite expensive to fulfill everyone's request. I'm trying to figure out how to make this possible?
@@RCexplained yeah, i gues you would have a rather big collection of batteries 😅 . I would lend you mine for testing, but we're not located in the same country. I'm relatively new in the rc hobby and I saw your other video on c ratings, very interesting. Tried a few times to get the internal resistance with my sky rc charger, but they differ every time. i'm not confident i'm doing it at the right moment.
Perhaps you could get people to lend you batteries from different suppliers. Testing them under the same conditions would make a nice chart.
Good luck on your quest, i'm subscribed!!
@@RCexplained I have worked with a bunch of companies. If you want to reach out to me, I can provide you with some good contacts and might be able to help you get some rest packs!
Thanks for sharing this video. I use nothing but Zeee batteries in my Limitless V1 on Neu and TP motors. Because I have no other batteries to compare mine with I thought they were OK but now I see they suck. Maybe I should try CNHL or ONYX
Perhaps they don’t suck. It depends what pack you have. The 7200mah pack could perform great and the 8000 pack sucks.
@@salesale204😂😂😂
Try getting the IR as we've done in this video. Both 1min in to the charge and loaded right from the ESC data. This will give you some insight.
All the CNHL that I've never changed above 1A of their capacity, and always kept in storage when not in use, have swollen without any visible damage on the outside, and had to throw away within two years of weekend use (not intensive).
I've had for an additional year one of the shorty 4300mah 50C shorty, and that keeps on trucking with low resistance when charging, never overheats, hasn't puffed a bit, and gives solid performance.
Cnhl 70c g+ can't be beat for the price vs performance. I did 132mph on 3s parallel with 1/7 scale GT. I did over charge to 4.25v however. The 6000mah are great if you can fit them
I find that the Zee packs are exaggerated, but having said that, they are doing well for me in aerobatic airplanes
Nice, you must be using another model or line of their packs.
I have just bought two packs. But i have returned bought. The problem was that they get handwarm when i charge them with 1c. Always not a good sign. The celldrift was about 0,3v. Too much for a new lipo in my opinion. I got also 4,5omh. Not a good batterie
Interesting, thanks for the comment.
What if it’s not a connection issue? I hook up a different motor and it works fine.
I'm not sure what you mean?
@@RCexplained I’m sorry, that comment was for your brushless motor stuttering video. It must have auto played to this video before I got to write the comment
Try changing the wire sequence around and also try changing esc settings.
@@RCexplained that didn’t help. I’m afraid there might be a bad connection within one of the wires closer to the motor. When I check resistance between the 3 wires, 2 pairs are .7 ohms and 1 pair is 1.2 ohms
@CollinRenaud to check resistance you'd have to use the drill method. There's a video on the channel on this.
Are these packs still good for bashing?
yes. if they get warm then turn your TH end point down 5% until they're staying around 100-105f or something well below 140f.
Capacity of these packs are brutal. There are better options at this price.
@@RCexplained what packs do you like in the 8000mah + 4s for bashing? Leaning Gens Ace or SMC
I've had the best luck with Turnigy graphene. will be testing more packs soon
I got two 3S 5200mah on sale so I figured why not. I run them in a 6S felony and they don't seem as good as my gens ace. They were also considerably cheaper.
Great review. HRB for me
Nice!
Do you know what the IR is at what current load in the car?
@RCexplained well.. mine are in scale helis weight about 20lbs..with avg Amps at 37. My new HRB 22.2 in series at 5000mah (44.4:) are still at IR of 1.18ohms.for both packs. I've flown 5 times. I always charge them on accurate charge at 1A/C
Do you know when the IR of 1.18 is measured. Is this one minute in to a charge with packs at room temperature prior to the charge?
@RCexplained this is when the packs are finished charging. Honestly I didnt take that measurement. The packs are rate at 50C.
i have Zee premium 9000mAh 120C but thay have IR 7.2mOhm room temp mesured with YR1035 resistance meter
🤣 how to finde better?
Do you know if the resistance measurement is accurate? Was the 7.2 measurement taken in the first minute or so when charging from 3.80V?
yes i check them same way as you on youre video always came out to around 7 to 8. on istd d2 mark 2 even goes to around 9
@@RCexplained
@MrAtomek321 wow that's high. The Turnigy Panther batteries will easily outperform though and are one of the best I've tested in my limited testing so far. There's so many batteries out there.
@@RCexplained i tested also zeee 6000mAh 3s 80C and they are coming around 4 mOhm. Little bit better internal resistance but still way off from 80c.
This week i will get hobbywing max6 g2 and will test them under load. With data logging
@@RCexplained with 40 Amps of load voltage drops from 25.5 to 23.5🫣 from this it comes out IR of 8mOhm and voltage spikes to 27Volt🫣 but spike was probably my fault because i was testing it with wheels in the air
If they are all you've tired then they will feel good. Use a decent high quality pack and you'l never look back.
They give out most of their capacity from 3.7 down to 3.45v per cell. And they drop voltage under load fast !!
They really are not good at all for anything.
Someone else did mention capacity issues and I've seen the charge capacity was poor from 3.80V to 4.20V.
Bought a 7200 4s battery last month, very disappointed, the cells are clearly not matched. The capacity is near 4000mah at a discharge rate of 10-25amps max, as per an intelligent charger and telemetry.
Yes I am not impressed either at all with the 2s packs
Well seeing as im not going for top speed runs these batteries are great im my sbr 2.0. Last for about 30-45 mins at 8s.
If you are not concerned about getting a 100C battery, you are ok!
@RCexplained so in theory if i did get real 100c batteries my sbr 2.0 would be faster?
Yes but more importantly, your system would run better and your ESC would be happier.
@RCexplained cool, thanks. What 8s set would you recommend thats affordable, its always good to have a back-up set for longer play sessions. Thanks
Turnigy Graphene Panther
Contact the manufacturer to find out what kind of sustainable amps the batteries can handle. 800 amps is a lot.
I'm not sure what to expect, they rate their packs for 800A. They must say 800A or we all have a problem.
Large mAh commonly have high internal resistance or the mAh dosen't matter on the internal resistance
The data I have shows a very strong relationship for mAh vs IR. IR decreases as mAh increases.
@@RCexplained Interesting
these batteries really suck as you said, on mines even the capacity is way too low
Yes, this I've noticed as well. The capacity is bad. Useable capacity is quite low.
I just ran a test on my brand new Socokin 6500mah 100c with a icharger 380 duo.
preliminary results - 13.9c
***HOWEVER***
with a small charge and discharge cycle IR dropped to 2.5mΩ @ 50%/3.85v = 20C
that is 90A output at 70f room temp then with heat 130A output. BIG DIFFERENCE
I would say you need more data. You need to take C ratings average after a run, room temp, maybe 50f and average them to get a real world idea of where and what your batteries can put out.
Hello, thank you for the data. I understand what you are doing by manipulating IR using heat within the pack.
The formula on the spreadsheet is setup to use the one reading obtained at the one minute mark of a charge cycle. In otherwords it already takes in to consideration the IR changes that will occur when the packs builds heat.
I am looking to improve upon the spreadsheet in areas where I can get greater accuracy. Including, as did mention in the video, using an average IR vs peak IR.
Have you also tested the maximum current rate that pushes your batteries just below the 60C / 140F mark?
@@RCexplained I run these packs in a 42" catamaran with a 5670 TP power motor in a 12s configuration. At 6,000w I have yet to reach 140f. But theyre new. data still coming in.
Very nice, are you averaging 6000watts during your run?
Sounds like a solid CAT build!
@@RCexplained yeah mostly. I run on an IMPBA 1/3 mile oval course. So my data logs show a pretty consistent graph even while cornering. I do not always run that aggressive of a prop though. With this setup I run about 2 laps only. about 45 seconds with 147A average.
