Who will be the new king when it comes to esc's?

Why change anything? Just go 20s and nobody is forcing you to go at that new topspeed?

By changing nothing you’ll get less torque at low speed I believe.

don’t think so. At least I did not experience that with previous jumps in voltage on my batteries. Voltage should give you higher top speed and the need of less amp for the same torque.

So higher voltage basically won’t add more stress to the components? We can just dump bigger battery and a 100D stormcore and go Zooom like a :penguin::boom::dash:

well motors and mechanical parts spin faster so there is more mechanical stress

If you are constantly going 40mph…

Motors would be the bottleneck in this case

well I am saying that in theory. Overall if you have more speed you will spin stuffs faster than before. Otherwise if you have 20s and go 20mph then no need for it :crazy_face:

Torque delivery?

that more amp honestly. Yes you can have more torque for less amp but in reality increase the amp and you get more torque.

We’ll see…I’m going by what Alex said in a podcast

I think the best gain from higher voltage is the less heat in the wire, motors… Do not think we need extra speed in most of the cases. 100v is a good thing on other electric vehicles, for esk8 12s can give you the power to fly. Same for the speed. That being said I like the idea of getting higher voltage esc to experiment stuffs, but the available space we have in the enclosure is such that if you increase the s count then the p goes down or we need to go around with a closet on the board :smile:.

I am interested to know if torque will be better with higher voltage. I would like to be able to go fast uphill without loosing weight.

well if you think just at the same set up and you go from a 10s3p battery to a 12s3p battery and keep all the rest the same. Then you gain voltage but not amp. Although your motor now will spin at the same speed less amp, so you will reach the same torque with less amp, meaning you hit the amp limit of your battery at higher speed than before. hence you gain torque too. I definitely felt more torque with higher s count. Also your battery gets bigger so less sag.

Quick rough answer : it’s all about the total watts. More volts but same amps? More watts. So more torque.

And what @moon pointed out is also true : you won’t overuse your gears at same speed, only at higher speed but anyway you can select your parts and keep your rpm and all within specs. This way everything is ok.

Btw You can do the same result with higher Kv motors and lower voltage. So in the end high voltage is not an issue per se.

Totally unrelated but do your remember selling those on ES? Have you used them, I left them in a drawer for all this time and just saw it now.

Bahaha! This is why I come here every day.

Yah close parallel in quad world can look up 4S vs 6S for 5" quads and see the debate there too :smiley: get less voltage drop at higher volts cause less amp needed to get the same watts delivered people typically get better flight times but if using 4S then use 2600kv or so and if using 6S use 1800kv or so so end up at same rough rpm on the motor output. Voltage is often limited on all the electric components though like capacitors and mosfets so higher voltage stuff is generally more expensive.

Also physically bigger for higher voltage electronics… I lost my right to edit.

Omg I forgot you were part of the group buy!! We had the Kv for everyone but I got my shafts shortened and inverted haha

50mm 85kv motors from E-Max right there :ok_hand:t4::fire:

Not yet, I disassembled mines to add some structure for DD/Hub use in my inlines + do experiment with them (rewinding with 18awg wire, extra magnets, big ass bearings) and these are still waiting for reassembly. I tested them before dismantling tho and they were spinning smooth on VESC Tool. QC is good and inner bearings tolerance is tight. For bulletproof you might want to seal the magnets in extra epoxy before use, so you’re sure they never move.

Also my lazy ass bought two Landwheel L3X hubs from @BearBoi so I can just focus on outer structure and not mod these ones, quick design for integration in my 110mm wheels.

You have a plan for them? They’ll do great on higher voltage for instance :grin:
