That’s only one side, with a battery that is not fully charged.
Just noticed youre in Bacchus Mal, very cool
Edit: I am wrong in some way here, ignore me
Imma be honest, I’ve always measured my board’s power by what the battery provides, not what the motor receives. Motor voltage is rated down as motor current increases, so the voltage shown in the log is battery not motor voltage. I seen a peak of 192A on the motor, but this could be at some tiny voltage level on the motor side. Am I wrong?
I’m sorry, are we not measuring motor current? Because you know, what can the motors do?
To know what the motors are doing you need to account for the duty cycle. Afaik If the duty cycle is 50% then the motor is only seeing half the full system voltage.
193A * 56V *42% duty = 4.5kw. an impressive number no doubt. Especially if this is per side. But not 10.8kw.
At no point can the motors be putting out more power than the system is taking from the battery.
Oh okay, noob mistake then. Well you learn something every day. Thanks!
I’ll have to add that into my calculations from here on, and start flogging them harder. 
Was that log per side?
Nope. You can click on the combine button on the log to see per side.
Metr is so cool!
Now I really want to build a 20S6P 26650 A123 pack.
Was gonna say, what battery are you using right now?
20S1P 40152S Headway pack.
Christ nobody ever really wants full system voltage in the motors you’ll die. After the light bends and you turn plaid, you die.
yes but you’ll die a tartan death
One step past ludicrous.
Gonna have to start pulling the full 100A from those!
I’ll try harder. Voltage sag sucks a little though, hence the want for the A123 pack.
Yeah. This is my 18s4p p42a pack I’m building
Should be good for peaks of up to 180A or continuous output of 120A.
Using some conservative estimates. The 18s pack should have a nominal voltage of 66v and be easily able to handle continuous outputs of 8kw. At full charge and under full load it could peak at closer to 13kw for brief periods.
And that’s not even a big pack, less than 200x200x80.
Hopeing this is enough to get a real metr log reaching 10kw through the whole power train
If I’m right a 20S6P A123 pack can deliver 180A continuous (or is that peak? IDK), so that’ll set me up for the same power output.
i’m fairly confident that before this time next year someone on this forum will be rocking a 6s74p battery, on a skateboard (driving your model s doesnt count)
