bro the amount of videos you have for all my questions i find myself just clicking on your for your you professionalism and easy to learn content

I wish all subjects in my school were taught by a Joshua Bardwell.

This video is really helpful

thanks for the answer to my question as well

Luckily a battery chemist hasn't come along and critiqued Joshua's "the ions get squeezed out of the battery" explanation. :)

The workaround would be double the cap on power and have two connectors to the tab parallel

I use some old 20a littlebees on a 220mm frame with 2206 2300kv motors and 5x4.3x3 props. Carries a gopro on 4s 1500mah with enough thrust for some acro and the motors and escs never get very warm at all. For your average pilot, 20-30 amp escs get the job done and are less than $4 on aliexpress. Even on full throttle punches, battery output limitations kinda keep anything from getting out of hand.

So my 15A escs can handle 15x4 or 60amps. And my 1204 motors can push at max, on a 4s battery, 5.6amps. Therefore the 4 motors will pull 22.4amps at max throttle on a 4s battery, and my 15A escs can more than handle it. Thank you!

With exact same electric power of the motor. You need more amps on ESC if you use 4S instead of 6S. That is one of the disadvantages of 4S. But at the moment you will get that money back because 4S LIPOS are cheaper than 6S...

wonder if 1507 motors with a 20amp for a flywoo explorer will do fine? i dont fly acro... so not harsh inputs

What's is a budget brushed esc that will work with an 8 turn motor ?

What's a budget brushless esc that'll handle an 8 turn motor ?

Thanks😂

Well then there's the bottleneck in the system Xt60- 60amp cont 80 burst 6-10sec Xt90- 90amp cont 120 burst ... Xt60h-90amp cont 120 burst... the one on quads That's why I always thought 40amp... was the whole board not per motor

Xt60 can handle 180 amps for 10 seconds

So, why do I keep popping my esc's? This is an ongoing thing with the speedybee f405 v3 50amp stack. I've gone through 7 3 being full on blow outs with fire. These are super clean builds, and happening on 2 different drones with different parts, different motors..... I pull 83+punches with my other v3-50amp stack and I've been running it for 7 months. These stacks I've purchased from Amazon, and ALL of them have failed esc's. Has it been heard of that Speedybee is selling failed product on Amazon? BTW its May 2024 I'm in Canada. I'm pretty sick of blowing up drones I spent serious time and energy building. Hard to get away from the stacks cause I bought them, return them to get a new one....... I read somewhere that flashing bluejay will do something bad to the v3 stack, is this true? I mean after thoroughly looking through the v3 manual it clearly shows flashing bluejay is fine, flash JH-50. (WHICH I had been doing anyway) well I just got the new stack from Amazon in my source 1 v3 frame (cause that's the one it's taken serious beating from...... and push it. I've changed out everything on the drone.... this time running it simple.... no led cob lights, no race wire. Nothing fancy. As if it pops it can go back to speedybee with the other 2 stacks that are to go back next week so they can determine what I already know. They are defective. I've checked all motors/screws..... basically everything you can think of that can do this, and it's all good. I've built them solid. Had others look it over. The 2nd drone is a brand spanking new Mario 5 frame, full dji 03.... and it flew perfect. Then luckily I went to fly it and noticed 1 motor wasn't spinning. Plugged into Bluejay "missing esc" its when you start messing with it, and your able to boot the esc back up again when you get fire bomb esc's. Well least that's what the last one did, redid all firmwares, seem to boot, went and flew 3 packs, caBOOM..... garbage. Any assistance is MUCH appreciated, thank you kindly.

Speedybee ESC’s have just been known to do this more than other options on the market. Take a look at Hobbywing or T-Motor!

Thank you so so much. I had a realy tuff time to find somone that explains this topic. I always was so afraid that my ESC prowides way to less power becaus i thaught lets say 55A is all you have... if you go over because my motors alone pull 160A in full trottle your quad goes puff. But its 4x55A !! oh man. i with i would have found you way earlier.

Excuse my english by the way. i am not a native speaker.

Is a 45amp esc good for 6s ?

The Amp rating and the battery voltage are only part of the equation. You also need to know the all up weight of the quad, the KV of the motors, and the pitch of the props. Right now, I am wanting to put a set of 5149 props on a 55Amp ESC, but the manufacturer of the motors show that in testing, a 47-pitch prop pulled about 53-Amps. So, I might be close, or I might be fine, depending on the batch, and how I fly. The best answer to your question is, look at the testing data on the motors, the ESC, and compare that to your quad. Shortest answer, without looking up data, I would say, use a low pitch prop, keep the quad as light as you can, and you will probably be ok. But there is more to it than just amps and voltage. I also had a quad, last year, with a set of Xing-2207-2755KV motors, on an ESC that was rated for 55 Amps, with a 6s battery. If flew absolutely amazing! But… the first time I crashed, I blew the ESC.

Look at motor thrust table. Match the prop and volts you will be using. Ex RCinPower 2306 1880KV, DAL5050, 22V = 32A. More expensive ESC are typically heavier, with more premium components, and higher AMP rating because tougher - they generate less heat (from FET) and handle it better. Typical AIO FC 3x3mm FET = JMSL0302AU. 30V. Rds = 1.2mOhm. Can handle 90A @100C 20W. Obviously real world 90A is impossible, because its not 1 FET with giant heatsink - its 24 on tiny PCB. Obviously, heavier the quad (ie CINE with GoPro), and bigger and more agressive prop = higher load on ESC. That is why CineLog mfcr put 2105.5 on 3.5", with 45A ESC - but on a super light toothpick with light biblade , you can use 1404 and 12A ESC.

so my 2506 1800kv motors will be fine with a 50A ESC on a 6" build?
