Re: 14S VESC ?

I'll bring it down to 165 which is seemingly the limit then I guess but if it truly can't measure the current why haven't I blown up? maybe the 200 amp currrent is smoothed out to a lower current by the time it makes it to the sensors? the 200 is the best performance I've had and without getting the...

Re: 14S VESC ?

Been running at 45 battery amps and 200 motor amps happily. Is there a risk doing this? I'd heard there was some loss of over current protection or something. Running a single hub motor with 12s foc. My other confusing question before..is it less efficient to run with a high voltage battery that giv...

Re: Vesc lvc and braking downhill

How can a circuit be made so current flows in the vesc and lights come on with no battery, yet if the full current were to flow it would destroy the vesc?
The difference between what could be generated and what is...how is that happening?

Re: Vesc lvc and braking downhill

everyone so far has been saying theres no power being created?

just trying to find out how it works. it creates power but how is the amount produced limited or determined?

Re: Vesc lvc and braking downhill

ok...ok..
but....
there is some power being generated as the lights on the vesc go on when batteries aren't connected and you ride downhill. there is a complete circuit in there

Re: Vesc lvc and braking downhill

no one has said where the energy goes! there seems to be confusion. I believe there is power being created by the coasting wheel no!? obviously so as it'll destroy the vesc if there are no batteries. yet the batteries dont get charged unless going fast enough. where does the power go!? that's a fair...

Re: Vesc lvc and braking downhill

but coasting does generate power, enough to ruin the vesc quickly if there are no batteries. just coasting. so I was told. coasting will light up the vesc without batteries too. power seems to be generated and curious where it goes if there ARE batteries since they aren't being recharged. i understa...

Re: Getting max power using the motor and battery amp limits

sorry if you were expecting the motor stated limits there aren't any. I've got temp limits of the magnets and wire enamel but that's it. the motors are 4725 stators and the amount of power they can take is unknown and I'm trying to find out the max power possible. I appreciate your knowledge and hel...

Re: Vesc lvc and braking downhill

sorry just trying to understand how you can have a voltage yet no power. if the batteries aren't there you blow up as the power can be too much to dissipate in the vesc but if the batteries are there the batteries dont take the power either. that's what I"m asking about. where is the power goin...

Re: Getting max power using the motor and battery amp limits

I'm set to 70/70. The motors can't do that continuously but it's great for blasting up hills as u say. I'd like to get as much power out for short bursts and keep pushing numbers higher. Can I do this safely since there's a auto shut-off if things overheat on the vesc? I think I will know before I h...
