Re: bluetooth BMS?

I can set a "max balance limit voltage"
I havent really checked if it stops there, but it sounds like you have a problem if your battery gets unbalanced as soon as the bms stops balancing.

Re: Another "stealth bomber" build.

My disc is 203mm I think. I just looked, I have a few mm between the disc and swing arm. But as you can see I have modified my swing arm, so I have a little more room on the brake side. I dont really protect the wiring, but I have made some extra room in the swing arm. I am pretty sure I have posted...

Re: Votol EM-200 Controller

Is the em 200 a 30 fet controller? I am thinking if the em 150 can do 500pA reliable, I guess the em 200 would do about 625 then.. If it is 36 fet, about 750pA? That is if it is the same mosfets, and somewhat equal load on the fets. The em 300 still seems unavalible. I saw a picture of the internals...

I dont see how this is related to the problem with the bac 8000 anyway.
Maybe you can ask the seller of asi controllers in the "items for sale, new" right here on the forum?

Re: Chinese Grom Clone with 8K QS Hub and Nissan Leaf G2 battery pack build

No harm in trying it with the controller you have, but it would be a shame if you thought "is this it, not very impressive" When you are no where near using the potential of the motor. But I think you need to do something about the dropouts, or maybe the whole swing arm. It is good to make like clam...

Thanks Dui! I read all your posts. Really cool stuff you are fabricating to make your bikes great! I should receive a Kelly KS-S mini controller 72v good for 300A for 20 sec and 120A continuous. I am just getting this project together and bought a few controllers as I was conceiving the bike. I sus...

Re: Votol EM-200 Controller

I think you can find some info about regen in the EM 150 thred.
As far as I remember it is just a matter of setting up the right port the right way.

I am one of those that is running 500pA and 300bA with a EM 150 :wink:
I am also curious about what phase amps the 200 can do.

Re: Votol EM-100 & EM-150 controllers

Strange that it is showing 0v, but if you try to run it on 40v maybe you should set your lvc lower than 40v?

Re: Is regenerative braking really worth anything?

I sure miss the variable regen on nucular when I had it on my dirtbike. I could use it very careful going down wet rock, or lock the wheel on the road if I wanted. Much better precision then sometimes dry, sometimes wet or muddy disk brakes that should be maneuvered with big boots. Absolutely worth ...

Re: Electric motorcycle motor choice

Are you sure 24s is a good idea? Many controllers use 100v components and can handle about 85v or up to or a little over 90v if you want to push it. I think 20-22s is a good idea in that case. Or you can go for a (more rare) controller that can handle more, but in that case no reason to go for just ...

Re: KTM 200 exc goes electric

I changed front gear from 10 to 11 tooth at the same time, actually it is because of that I changed the rear sprocket. The change in gearing is not much, I went from 8:1 to 8,18:1. I wanted to change front sprocket because the chinese ones have play on the shaft. Some people have broken the splines,...

Re: Votol EM-100 & EM-150 controllers

I think step 1 is to get connection with the computer to check the settings, then try to get the motor to run.
How should anyone know if 40v is enough without knowing your lvc?

Re: Votol EM-100 & EM-150 controllers

I have only had that problem when I tried to use HDC.
But I also have HHC in my program, in yours it isn't there.
Maybe try a different program to make sure that it isn't on?

But you also say the motor doesn't sound good sometimes, maybe some motor settings is wrong?

Damaged MOSFETS in the controller perhaps?
Probably. I doubt that it is because of the damage to the hall ground.
If there are no damage to the phase wires it probably is just the controller quality.

Hi guys..
I have Votol Em-100 controller for my folding bike (60v 20ah Battery with 10inch 48v 800w BLDC)
Is it usually 9600 and no can?
It depends on what controller you have, but my em150sp is 115200 and can.
Is it com3? It looks like that is what you selected.
