Re: KT controller not switching between 36 and 48v batteries

The "automatic" detection of battery voltage of KT controllers does not work really well. I had always the issue that connecting a 48V battery when it is almost empty, the controller detected as a 36V battery... I would prefer it to be selectable more than automatic... For what you say I t...

Re: Fully 3D Printed DIY electric car

It seems pretty reasonable. Not sure what controls your relay (is it for flashing?), or how the brake signal works. Thank you Addy. Yes the "relay" (maybe that is not the proper name) is the device that makes to intermittently flash the turning lights. I just discovered an error in the sc...

Re: Conversion of a Bultaco Sherpa

Cool project and nice motorbike.
Following with interest your project.
One detail that I noticed, the bike has a rear rack (I suppose aftermarket), in order to improve its looks, if I were you I will get rid of it.

Re: Kelly KBS-E controller Variable Brake Regen setup issues

I tried connecting pin 13 to 20 via a connecting wire from the throttle -(black wire) to a pin that connects to pin 13 ,thereby closing the loop as if brake switch is turned on, and now throttle doesnt work either. That is correct and what a switch brake should do, when you brake (activate the swit...

Re: Kelly KBS-E controller Variable Brake Regen setup issues

Like TommyCat says you need a switch that activates the brake. But not pin 3 :warn:
The no. 13 pin has to get shorted to ground (pin 20) to enable regenerative braking with this switch.

And you are right on newer versions it is not need, but KBS ones are old models. :(

Re: Why not heat my house w heat lamps?

My opinion:
To use heat lamps in order to get light and heat is feasible, but usually happens that the light points position is not the optimal for a heat source and viceversa. So most cases it is more efficient to have them separately.

I bought the 5T motor. The 5T and upwards are the medium/slow motors, I do not have the full details on your precise motor but it provably is around 10KV (10rpm per volt), so 1000rpm at 100V that is around 114Km/h for a 24" diameter wheel. I believe it is a 16 PolePair motor so 1000rpm x 16Pol...
