OK guys, it is now June 2021.
What is the best lower power ESC?
What is the best medium power ESC?
How about high power ESC?

imma say makerx go-foc retro
i don’t know about others catagories, is 60D even consider as medium power when it can do 80amps cont. motor amps?

This word is hard to define.
There are so many ESC options now that it really depends on your specific needs, budget, desires, and how fast you need it.
For example, if building a Funwheel it’s going to be a lot different than building a short commuter which will be a lot different than building a monster eMTB, which will be a lot different than just building a toy to have fun with on a budget. Also whether you need an IMU or not, as well as how high of a voltage matter as well. Also your space requirements: some ESCs are physically larger or if not large just a different shape than other ESCs. Or, maybe you have heatsink needs that confine your choices.
2020 was the year of the ESC, so many on the market now it’s silly.

Ok… instead of best, let’s narrow down a bit.
- Budget 30amp, 40amp, 50+amp, etc.
- Starter FOC/VESC for single motor
- Starter FOC/VESC dual motor
- Intermediate FOC/VESC single motor capable
- Intermediate FOC/VESC dual motor capable
- Money is no object for my build
- Ultra cheap but gets the job done
Can we have some suggestions for each item based on the criteria in the respective item? I am afraid my lack of knowledge shows in this post as I am not even sure these are valid criteria to begin with.

What’s the difference between the Maker X retro and DV4?

Personally, I am looking for a lower power VESC for a new dual motor set up. No more than 40amps.
What do you mean by low powered even the small compact VESC are 75-80A normal up to 100A
Low powered is not really a thing compact is a thing
The motors we use
6355 55A up to 63100 80A so thay work on any VESC so don’t need low, medium or high power only exception is huge 80mm can motors on monster builds. you get difrent Sampaling on the larger Vesc’s making theme more accurate and smooth.

Are we talking continuous or pulsed? Motor current or battery current?
Because all ESC are not made equal and cannot dissipate as much Amps as some others so there’s that.
In VESC side, smallest stuff like MakerX mini, I wouldn’t push above 45-50a continuous for sure and wouldn’t even FOC above 8S voltage either.
Keeping it under that seems to have reliable results!

I was just taking manufacture specs you mention maker x so I went and screen shored the spec. A 3655 motor can not pull 55amps continually with out over heating it’s all about balance
What I’m saying is you can not catagrisr VESC by power level it’s the wrong way of going about it it’s the same as comparing vechals by engin size. A 2L BMW can not carry as many goods as a 2L transit van. Both can do National speed limit. Same as Almost all VESC can run all most all the common motors in eSk8.
The most common split between VESC hardware
VESC 4 and 6
Compact and full size
Types of sampaling 2-3 fets hi side vs low side
Then there’s a few unique designs out there as well that have gone down routs of over coming things like fet’s limitations

I get your point, and quoted MakerX mini because it will overheat way before it reaches ratings quoted above on the spec sheet.
It would need better cooling to bear 80A at least.
Also this category only applies to Vedder based ESC, cannot use it for anything else (ex : Castle esc used on SRB)
I believe the idea to classify esc by power ratings would be to help select an ESC based off your needs.
You’re only doing sub 25mph in city without big hills or accelerations? You don’t need a 10kw esc for that.
You’re pulling drag races or off road on regular basis? You’ll start looking at that 10kw esc or the best you can have.
Both can indeed do regular commuting but not both can do extremes

Manufacturer specs are often heavy on the marketing and light on the science.

I agree but so are the motors over optimistic but possible normally with the correct cooling
other categories
HV (over 12s)
Dule motor controllers
Budget
The naming of the VESC also gives a clue as to there category as to what to compare it to
Mini as in maker x mini
HD (high density) as in Tramp HD
Are some of the obvious ones that come to mined.
Sprinted with their remote amazing features for the money. Medium power? Outstanding customer service.
Heads up that dissipate means to waste, and in physics and engineering it is (basically) only used for the dispersion or removal of heat. For example “That heatsink can dissipate 50W in free air” (discussing a good property of a heatsink) or “that wire dissipates 2W when you put too much current through it” (discussing a bad property of basically anything other than a heatsink).

i’m not active anymore so i’ll mention one that people was hyped for. Stormcore ESC. Now I just saw this. Man ESCs these days are just powerful.

Which VESCs have high reliability and ease of use?
Flipsky FSESC 6.6 DUAL with big caps and no built-in antispark
Flipsky ESCs are the last thing you want if “reliability” is on the wish list.

Using an ESC at less voltage and current than most other folks use them at can increase the reliability many times over. So if reliability is your goal and you take an ESC that most other folks are running at 12S 50A battery, and only run it at 10S 30A battery, then your expected reliability will be far higher. This is how to make reliable.

Are you factoring in the higher RDS(on) that coincides in mosfets rated for higher voltage?
HV ESCs are not necessarily well suited to be run at lower voltages.
