Preferred ESC in 2021

DIY Builds
41

Sure, but “buy a big one” is a bit vague in this context. Solid componentry choices and a high cont amp rating would be my preference.

For reliability, I would sooner recommend folks run 10S on a 12S spec ESC than recommend they purchase a Stormcore 100D and run it at 12S.

On my current build, if I had a 60D running at the same voltage/amp settings, it would run a bit cooler than it does on a pair of 100S.

So, imo, the answer here for more reliability would be to go with the lower heat option as transients aren’t a huge factor anymore. Lowering your boards power ceiling is the opposite route most folks are going, and not really an option on bigger boards if you like going up hills.

What do folks think presents a bigger danger to reliability? Transient voltage spikes or heat death?

good to know, plus we might be the same weight so I should get similar experience with mine :grin:

I would have thought that people buy higher voltage capable ESCs to actually use that higher voltage anyways.

I think you’re really fixating on this technically correct statement - that they would create less heat - but not using it to draw useful conclusions given the context. There is less heat, but by the nature of running something below its rated currents anyway you’re inherently a good safe margin from the breaking point.

Rather than the marginal increase in heat, the benefits of a stormcore at 12S vs a unity at 12S come in lots of other beefy components well below their max.

I bought a Spintend in the mistaken belief that it would be overkill and thus increase reliability in all areas. Live and learn. Needless to say, it’s temporarily out of my board for other reasons.

He has yet to notice there is a control to turn down the heat :crazy_face:

We’re talking about two different things at that point.

I’m saying that given my desire to run 85 battery amps per side, going with a 60D would present less heat.

You’re stating another way of lowering heat is by lowering the power ceiling, which is not something I’m willing to do. If I want lower heat at the same settings, I’d need a bigger heatsink and/or mosfets with lower RDSOn.

The only benefit to an HV ESC would be additional protection against transients, and I feel that is a risk that is being overly spotlighted.

and here is where the secrets spill out

This is why he doesn’t understand.

It’s a goalpost move. I said in the first post at lower current.

This is another way to say lower current and lower voltage, which is precisely what I suggested.

You probably shouldn’t do that then.

Yeah I get the logic here, but to be fair we have been talking to a new builder about buying extra power as a safety margin above where they need, rather than talking to you about restricting your power to below where you need. It sounds like a nitpicky difference in framing but like, it’s important

I addressed this in my 2nd post.

Obviously lowering power will lower heat. I’m not sure that was ever a question to anyone here, much less a stance being taken. That’s pretty straightforward stuff that I didn’t think needed repeating.

I was challenging the statement you initially made (and have since edited to correct) recommending people run HV ESCs at 12S for more reliability.

My statement on heat differences in my build using the same settings and a 60D vs 100S is valid.

I stand by the statements I made which was lowering voltage and current to increase reliability.

Brian, you seem upset.

I’m here all day dishing out hugs bud. :kissing_heart:

LoL you dish out angst :rofl:

I am very happy, and can help you if you need help. This is clearly important to you, and I understand. We are here to offer support if you need it.

Hugs :hugs:

I think this could be settled in a good ol’ fashioned race.
Except you have to hold each other’s remotes.

Damn are you driving a hammer or why is your consumption so high?

I think the real life mario kart potential with ESK8 is just waiting to be tapped.

I think Summerboards/efreeboards are a better fit for that type of game though. Do 360’s to get rid of the slowdown affect someone hit you with!!

Still so early on :laughing:

Nah, I’d just have to go out of range of one of his receivers and he’d drive off the road.

That or bring a cardboard box.

Did a mario kart trip of 40km with a pillow and I can finally push the trigger to 100%(with my ultralight 12s1p build(1 recharge at 20km, we have free bike chargers in some cities) and the acceleration is so nice. :smiley: It is like a mini go-cart. Video will be uploaded in a few mins.

Well, I suck at riding, recording and talking at once xD
And a banana almost killed me there.

My setup is running a flipsky 6.6 mini(2nd hand)
and it is way overkill for the vesc settings of 15 bat. Amps and 45 mot. Amps on each motor but I also like to leave some room between the maximum I run and the vesc can handle.

The other build has 2 Escape`s which are so rare that my setup with 2x 30 bat. Amps and 80 mot. Amps is not helpful at all.
I know those settings are overkill but I wanted to go v6 after all the blown drvs I have heard of and I run 12s on both. Never had any issues except with the tool/firmware.
