Possibly among the TI DRV83xx family?

Battery is an em3ev 10s9p Samsung 32e so a conservative 28.35 aH. I think the BMS an cope with 40A continuous. So I think a peak of 35A should be reasonable. Not sure yet on what phase current I should use so any advice welcome.
CA v3 will have PAS as the main mode of input. Looking at 3 modes using the preset and digi-aux for this. Pot for setting pas to a cruising speed/amp draw/watt level when using PAS to achieve speed/range balance. Throttle is just to have an occasional power boost.
Preset 1 - PAS 250watt 25 km/h speed limit no throttle - starting setting
Preset 2 - PAS up to 550watt, pot can reduce this, no speed limit, throttle limit 1000w
Preset 3 - PAS up to 750watt, pot can reduce this, no speed limit, throttle max

Low state-of-charge foldback. I think this would only apply in a networked configuration where you have a BMS that's communicating with the controller to report the battery's state of charge. If foldback is happening, that means the controller is limiting the current, so it's worth figuring out which parameters would make this go away. Look for parameters with "SOC" or "BMS" in the name or description. It would be best to disable this altogether, but if you just set the foldback parameters to something really low it might work.Marc S. said:What is 'Warnings(11): LowSOCFLDBK'?
I actually had this warning pop up today when I was experimenting with some things. Solution was to set foldback start to 1% and foldback end to 0%.Marc S. said:Out of luck.
Doesn't change a bit.
(wraps the Phaserunner and puts it back in the box)
As long as this thing 'invents' new warnings and error messages every time I try it out, it doesn't go back into one of my rides. *sigh*
Thanks, anyway!
