so is this basically what i suggested
before?
It’s similar in that available watts would be based on your present speed with more watts available at higher speeds. Rather than a targeted watt hour per mile it is a targeted % of electrical watts converted to mechanical watts and the % value is chosen through a setting by the user… A lower efficiency setting gives more acceleration while a higher efficiency setting gives more range but less acceleration.
Technically though, even standard current control mode gives you increasing watts with increasing speed, because it takes more battery amps to maintain the same # of motor amps as the motor turns faster. The difference with efficiency control is the user gets to choose an efficiency setting value, and when they accelerate at full throttle the controller will allocate the exact # of watts that achieves that targeted % efficiency during acceleration.
Has anyone ever tried to use the pos and negative from the top of an 18650 cell to do something? Anything?

What about using a regular dual motor board that works as normal, but the front wheels have 2 small motors on them functioning as brakes only.
You could use a ppm splitter or a second receiver and the cheapest vesc you can find. It would be nice to have additional braking force and not skid on sandy concrete. The whole thing could be done with the price list below
3d printed motor mount clamp $0
Motor mount plate scrap aluminum/steel $1
Belts $8
Motors x2 $40-$60
Dual vescs $120 from aliexpress
Misc hardware $10
Total of about $200 for 4wd braking abilities and massive performance and safety increase

I’d rather go 4wd or stay 2wd and figure out how to have zero rolling resistance, no brakes via motors and use mechanical brakes.

Has anyone here ever tried to make an thumb adaptor to use a trigger remote ? Like a sort of lever system?
What’s your idea with it? I don’t see it helping a lot in building packs for boards, for mountain boards maybe, but you have to design a buss bar that doesn’t allow shorts
The Model 3 pack is built like that

No specific. It just crossed my mind. We always use the top and bottom…why not top and anywhere else?

I would only say that it’s not a good idea to spot weld to the side is the cell, the wall is thinner and in direct contact with the jelly roll, ultrasonic weld or some heat less bonding is preferred
Would it be possible to mount some wireless induction LEDs close to your motor cans so when it spins it would induce enough of a current?

I like this idea, also with a hall sensor you could work out speed and have automatic break lights.

Do it you won’t
I’d need 80->120mm tires in back to match the no load speeds or change the gear ratio

3D or 2D?
I make a straight line from point 0% to point 100%. Next I bisect line 0%-100% creating a point A. The vector is created first by a line from point A, through the referenced spiral point B to point C, a point in space. Points in space are referenced as Vector: 87.35775…% Distance: 686,739,974.97969…km

just follow the yellow brick road…
^ an infinite # of points in 3 dimensional space can be referenced using only 2 dimensions - the spiral itself is one dimensional - it’s a curved line so no area no volume
