I've had a few 4000 mah 6s turnigy graphene panther lipos and found them to be powerful but heavy and swelled quite quickly when bashing. it was a few years ago though. I just use the turnigy heavy duty 4000 mah ones now there good enough for me for the price

This is all good to know.I fly 35 inch wingspan planes and I never had to extend my ESC wiring.If I ever got a much larger plane,this information would become very important.ESCs are very pricy.

errrr....brrrr... errr.... bzzztt. brain just short circuited. LOL

If youre going for a higher kv motor to get more speed , but then you gear down with the higher kv motor to get a similar speed to what you originally had then what's the point of changing the motor at all? Lol

I'm confused....I'm running a 2200kv motor at 2x5000 milliamps. Where that 73 is coming from? How can you run such high amps? Thanks

Silly question. Who or why the changed the way if rating electric motors, I understand 700 W at 12 V and let say 7000 rpm. It’s clear and simple, so why to switch to the kv and turns ?

is the range as good as the rc6 v3. do you still get the 600m when there is no external antenna?

weight? did you forget .... best would be to raise the volts ... can c decrease .. carier

As long as you know the capacity of a pack, you can just make a label that states the current capacity, no need to toss it

Great topic thanks 👍

Question: Torcman offers many of its motors at a particular KV with a choice of winds e.g. 10, 12, 14 or 16. What difference does the number of winds make and is the difference significant?

Thank You for such an immensely useful video. Could you please share the sources/references for the formulas and the calculation tables used. Thank You.

Wait.. then what is the point of using a high Kv motor, if it has the same RPM and torque but draws more power and creates more heat?

This is the best beginner tutorial I've seen for learning airplane electronics. Thank you!

Can you try SLS SPEED EDITION battery?

Nominel meens nothing 3,6 or 3,7 its all the same , max charge is 4,2 for both lipo and li-ion, li-ion have more usable energi no matter if it says 5000mha on both the li-ion have more time running

Drag racing needs high c ratings for maximum speed

many thanks°!

I would never have expected this! Instead I would have expected all manufacturers would be advertising their regenerative braking all over the place, if it was a thing! Thanks for your fantastic and insightful content. 👍🏻

Hello, my 2S Li-ion battery says 7.4V is that false or is also available Li-ion with 3.6v and 3.7 v?????

The manufacturers of these batteries should be held to a much higher standard. It’s understandable that these batteries are used for devices that are categorized as “toys”. So it’s easy to inflate ratings with that thought in mind. But did these manufacturers forget that these batteries are being used in toys that can potentially cause great bodily injury? Imagine buying a battery for your remote control flying RC, only to have it fall from the sky because of inflated ratings. I guess it will take for something like that to happen before they are held accountable.

it would be interesting to see a max amps pack tested they claim to be the worlds best in rc

Why not do a video on battery heat versus voltage or current output??

I’ve been buying batteries from zeee for years. I get the capacity listed if not better, and they perform well in my vehicles. Including their 10k 4s packs on a max5 5690 combo in a xrt. I know their C ratings are bullshit, but I’ve still had better from them than the likes of spektrum and traxxas. SPC batteries actually had extreme swelling for me, popped the hard case. Zeee packs have been stable. How ever I have gotten some bad packs from them, but unlike the local hobby shop, you can return these packs to Amazon even with the connectors chopped off

What battery went 80 seconds I would like to know

I have went through close to a hundred lipo’s in my boats and find there are no lipo brands I have used so far,telling the truth as far as C rating goes. As far as resistance goes I have some batteries with high resistance that go better than others with low resistance.

I REALLY Wonder how my gens 11000mah 100c delivers!! 😄

Another issue with the community is RCs being discontinued and unsupported after just a couple years or RCs that are still being sold having half their parts on permanent back order from every retailer including the manufacturer

I got a 50c 3s venom battery and its lasted longer then spektrum 100c 3s batteries

Test Gens Ace, Pulse Lipos, Zippy, Motion Rc lipos, Spektrum lipos

Great video

Ummmmm yes you can use a 2s lipo in either the dx5c or pro lol just have to remove battery tray and solder your own connector and it works. I have a 2S 3000 mAh gnb in mine

This isn't about Traxxas' lies about top speed? 🤷‍♂ They also try to be as anti-consumer as possible with their batts. A whole video series about how bad for the hobby Traxxxas (or Horizon Hobby) is for the average consumer would be interesting. People need to be educated that only mid-stage capitalism is good. Early stage is the wild west full of snake oil poison while late stage is monopolies and dictatorships.

they have to sell the B ,C grade cells somewhere. , lying is the norm

I need high C rate for my boats. I don’t trust the C rate. I go for the wire size. 10gauge. At least.

Battery ratings in mAh are like MPG ratings for cars....if you don't go over 10 MPH you'll get the MPG that they claim....and if you only drain your battery mildly, you'll get their top rating....anything more and the ratings will decrease....in both MPG and mAh

I bought a few Zeee batteries for my Losi MX ProMoto and they perform awesome for my style driving, lots of punch and long run time. So I bought a pair of larger (more Mah and more C rating) Zeee batteries to run in my Kraton 8s and it will run awesome for about 5 minutes then hit LVC. Let it sit for a bit and restart the truck and can go again like they were fresh batteries.

My guy is a hero we don’t deserve 🥹🪖🫡🇺🇸

Battery makers no most people are not going to test batteries to see if they are what they claim it’s already been found by people testing the ratings are way off they always say it’s a higher mah then it really is. This is pretty much false advertisement but no one is going to stop them from this so it is getting worse until some agency steps in & files a lawsuit. It’s ridiculous just put the correct info on the batteries. It’s the cell count that matters you run a high speed on a lower cell count & of course it’s not going to go as fast as the same mah count with a higher cell count.

If I'm racing max amps,or Onix and Amazon only good for cheap car parts for cheap cars

This whole video and you did not name one battery company. Awesome waste of time.

Pro Tek are always good from what I have found.

C ratings have been inflated at least 4X over on most affordable packs for as long as ive seen. 100C Zeees are legit 20C, which isnt terrible but its 5x worse than they claimed. Just be real with us, we'll still buy it if it works....

I'm wondering if the same battery series remains the same over time. In pc components they often are released with high quality components and later when reviews are done replaced with lower quality components (they do that with ssd's for example).

No they are not, look into the good Lipo companies like Onyx, SMC or CHNL (Cheaper) etc. These top tier lipos batters are pushing the limits of what we have ever seen. The cheep Ebay / Amazon lipos, yes. But I would argue they are just for toys but if your a real hobbiest then your going to want some good lipos.

I never expect more than 20c with any pack

Are you taking into account the temperature of the battery when testing ? At what temp are the batteries tested ? I ask because a heated battery will have a lower IR than a cool/room temp battery. example a battery of 90f vs 70f

The RC gods are pleased, you are doing the lord's work with exposing these scams!

I would really like to see a smc srd v3 8600mah 250c

The problem is many manufactures are actually selling Lion chemistry pouch cells as LiPos. These have 3.6v average voltage per cell vs 3.85v. True Lipos are Lithium Cobalt Oxide chemistry and can deliver 50% of their energy to 3.85v midpoint vs 3.6v for Lion. You can do a CC CV discharge test to see what the midpoint voltage is for half the rated mAh. 3.85v for true lipo and 3.6-3.7v for Lion pouches. Lion pouch and LCO LiPos can have the same IR, but LCO will still perform better because it holds a higher voltage under load (about 7%). Manufactures do this because the cobalt additive is expensive, and cobalt free Lion can tolerate a lower over-discharge to 2.5v before puffing vs 3.0v for LCO.
