In order to prevent Xyster from "spamming" my threads with solicitations for me to look at this circuit...
Hmmmmm... remember the "battery throttle" concept?

I will be installing double Milwakee chargers on bicycle , complete with the cord. So you can see each charger is switched between 3 batteries.
Before that batteries are separated.
Opportunity charging here in Alberta is aboundant with power left on after winter in many outside receptacles.

Being electronically illiterate i don't know if this is possible,
I'd like a net battery meter something that you input your AH + voltage (or better still it learns your capacity) making it adaptable to any bike. It constantly monitors your used amps at the constant voltage (subtracts from total)and tells you how much as a percentage (or some indicator) of full power you have left.
Allso a button to take you back in time to just before you did that thing that trashed your bike !

Can anyone explain how I could rig up an overheat cutout for the motor? Thermister in the moter, could it be configured to use the controllers LVC circuit? Or if too complicated, how about just a warning light that comes on over 80 degrees C?

And on a similar note, an adjustable max voltage cutout for charging?
Bonus points for a cicuit that does both
