Yes, but the difference in power output is not relevant in this comparison. I could've had the 2s battery output more power just as easily. The only focus point for this video is efficiency. The difference in power output is because I don't have the same 2s and 3s packs.
I was hoping to see comparison of 2s vs 3s on the same motor while setting both input power the same by limiting 3S input current. The goal is to see if lower current system is more eff / colder or not. Since all our ESC are rated by amp and not power. It would also be interesting if the motor output the same rpm. In theory, I would think both case would be identical or would it?
The esc actually did run a little less amps. the higher voltage allowed less current used even 3-4% difference shows less current needed to accomplish the same task
I love your content.... I really sit down and digest it. my question or request is to do a comparison of ES c's of the same amperage rating. say specifically a 120 amp hobby wing ESC versus say a cheap eBay blue ESC at 120 amps. Comparing each power's output to a given brushless motor say 3650 4300kv motor. Also testing each ones provided power, efficiency.. and test each one to failure, seeing which 1 fails 1st and mabye explain why
Thanks for explaining. Power output 2s=174W (0.233hp) vs 3s=214W (0.286hp) - the 3s setup will be able to do more work compared to 2s - ie can gear up more? Also say same capacity battery say 5000mh, 2s draining at 29amp vs 3s draining at 22amps means that 3s will last longer? So it is preferred to go higher voltage space weight permitting?
A 5000mAh 3s is 50% bigger and heavier than a 5000mAh 2S. This is because the 2S has only 2 5000mAh cells, while the 3S has 3 5000mAh Cells. So yes the 3S will last longer, but that is primarily because it is bigger and heavier, not because it is 3S. Given a 3S and a 2S battery of the same size and weight, the runtimes should be similar, assuming the motors have similar performance.
Hi supercharger, the only comparison you can make from this video is efficiency. Any other findings are outside of the scope of this video. Comparing the power output for each will lead to inaccurate conclusions
Very interesting. Ultimately it is the material quality(copper purity) that determines efficiency. Changing the winding to compensate the wire thickness is gimmicks.
Trying to build a catamaran with dual motors. What is your thought on twin 2s batteries with twin 2000 KV motors? Twin ESC's will be applied. Thanks! Btw your videos a top notch!
2000KV motors can easily handle 2S batteries. They might even handle 2x 2S batteries in series, making them effectively a 4S battery, though this might be pushing it a little bit. Personally I would go for 3S batteries for a 2000KV motor in a boat. That should put you in a nice and comfortable RPM range.
@@2testtest2 thank you for the reply! This really helps. I do have another question.. do you have a recommendation for a Y-harness that will plug into the Esc's? Would a normal 2.4ghz controller work on dual motor application? Thanks again
@@0utlaw_09 Yes any radio receiver should work. I just use a Y-harness that I got at my local hobby store, but you could also make your own, no need to go fancy. I have not tested this my self yet, but I believe you only need the positive lead to be connected for one of the ESCs to the RX. I have both connected, which does cause some odd behaviors when only one ESC is connected to a battery, but other than that it is seems fine.
Thank you for your video. I have a question. It is a thermal cutting function of ESC. this is done by temperature sensors or detecting current? If it's a heat sensor, can I say that every esc has a heat sensor? thanks~~
I can not say for sure what ESCs measure in order to protect them selves from thermal damage. I can however say with great certainty that a lot of ESCs don't have any kind of protection, and will quite happily destroy them selves if you ask too much of them.

Another great video - thanks! I noticed that although the difference in efficiency appears small, the difference in power output is significant!

Good job
Always a little to long, but good. Probably is hard to shrink

W&W C , this one provided the only difference is RPM output was the same? ruclips.net/video/X-w8rkeR6VY/видео.html

Very interesting, I’m curious about your dyn setup, homemade or commercial offering? Interested in doing some testing can you provide guidance? Thx!

many thanks°!
You are welcome!

Great info sir
Thanks
I will definitely tell to my friend s to subscribe your channel
So excited I got picked😍 @RCExplained looking in your about I cant seem to find your email address 🤷♂️ love your videos
under details
Interested in the dyno used for your testing. Home made, or commercial offering?
Thank you :D
You're welcome!
So in this case, picking a motor based on the manufacturer's data would lead you to the wrong motor ISFA efficiency!
Interesting
hope you create a bldc generator
Thank you for your video.
I have a question.
It is a thermal cutting function of ESC.
this is done by temperature sensors or detecting current?
If it's a heat sensor, can I say that every esc has a heat sensor?
thanks~~

@@2testtest2 I think esc must have either a heat sensor or an electric current sensor.
I'm just very curious about what kind you use.
And 4S better than 3S ? :D
could be, but there is no motor available to match output within this series.
👍👍👍👍 I sent you a IG message.
👏👏👏👏
This test of yours revealed exactly nothing.
