Votol EM-100 & EM-150 controllers

Isn’t this an apples and pears comparison? No 1:16 chain drives are running efficiently, single stage chain drives end at about 1:7 (adding idlers to get a better chain wrap will inevitably lower the efficiency.)

1:7 backdriving by chain and 1:2–>1:3.5 won’t be a big difference, i’d say preferable with the 1:7 as there will be less backlash. These are the types of drives people have here - not tesla reductions

Since debug info cannot point out logical failure of APK inventor. And I do clean a andorid phone to factory reset status, then test demo APK. Since not found any error. So maybe there's some different in your phone or controller infect the APK.

SO pls try these debug, you can tell if they work with or without fail-hints. thanks

As you exceed 1:6 single stage you will have issues. I have no idea what maximum reduction ratio someone would use on a dirt bike with largest diameter tires, but if you wanted 7.5:1 reduction then rather than a single reduction, using the qsmotor with 2.37:1 (19/45)gear reduction with a 3.19:1 (16/51) final reduction.




There are scooters using 6:1 reduction and when people upgrade to bldc with a controller that had regen, it can barely coast and adding the slightest regen locks the rear wheel.



So, for those having problems with regen set at 5%, the first place I recommend they check is the motor is easy to backdrive with power off, including and high single reduction gear ratio.

Hey guys I am very interested in this conversation but I am not sure about how the details line up. Could you catch some of us up that are following the conversation?

I think I am trying for the same front brake setup, where when I engage it lightly I automatically start regen on the rear wheel. I have High Brake and Low Brake wires, am I understanding properly that I need to find the EBS setting on page 3 and set that to High Brake? Then set a separate Regen percent to like 5%?

Also, my High Brake wire is just a single wire and my brake input is two posts, do I put the High brake into one input and connect the other post on the brake to 12v power? I also want to power the rear break light with this input so I guess I would tie the brake light to the High Break line so it gets power when the lever is pulled? I don't want to feed the High Break wire power if that's not what the controller wants.

Thanks in advance!

Yes, first you need the brakes sensors telling the controller what to do. But using high brake or low brake depends on your system.
What is your bike?
What voltage is your battery?
Do you have a brake light? If so what voltage is it running on?
Which Votol controller are you using?

I am converting an older YZ80 to electric. I bought the whole kit from Siaecosys.com with QS138 motor, Votol EM-150 controller, wiring harness, controls and display. So it is all a kit designed for the EM-150. I assume high brake is designed to be the front hand brake and the low brake is designed to be the foot brake or rear hand brake, am I correct? I do not intend to put switch on the foot brake, I will just use the switch on the front hand brake to activate the tail light. I have not installed the tail or headlight but I have purchased them and I went with 12v for both.

I have attached a photo for reference. All the controls on the bike came with the kit, switches on both sides, display, plus motor and controller. Has anyone bought this whole kit who can tell me where to put the 12v step down so that it feeds all the controls on the wiring harness?

Also, I am not sure where I will find the High Break input in the controller configuration and what input the controller expects.

Thank you!


I will put in a picture of the bike for reference

I assume high brake is designed to be the front hand brake and the low brake is designed to be the foot brake or rear hand brake, am I correct?

No, high brake means you apply a voltage to the brake wire when you activate the brakes. Low brake means you pull a 5v signal from the controller down to 0v when you apply the brakes.

I do not intend to put switch on the foot brake, I will just use the switch on the front hand brake to activate the tail light. I have not installed the tail or headlight but I have purchased them and I went with 12v for both.

Ok so you just connect 12v from your DC/DC converter to your front brake lever sensor and then connect the other wire from the sensor to the controller high brake wire and the 12v+ connection on your brake light. Each time you squeeze the front brake lever slightly the brake light will come on, motor will cut power, and any EBS you have set will kick in.

where to put the 12v step down so that it feeds all the controls on the wiring harness?

You need full battery voltage going to the ignition key switch, and then the wire leaving the switch must go to:
1. The controller ignition wire.
2. The display power (so it can read Voltage)
3. Any accessories that can run on battery voltage but not 12v
4. The DC/DC converter.

Then the 12v from DC/DC converter goes to all accessories that work on 12v (headlight, taillight, turn signals, horn, etc) and also it goes to the front brake level sensor, then after the sensor to the brake light and high brake wire (probably purple but check your wiring diagram).

Then set the EBS ratio on page 3 of the program to 5% and make sure Low beake (Thats Low Brake) box is not checked. Most likely the port is already set for high brake.

OK, I fix some code different from my controller. Please test it.
If there is also have the same display, please change setting manually on "Over Voltage" settings... etc. to make sure the setting is fit your controller. There might have two reason to have errors between your controller and I don't. One is our setting protocol have some different, so there's some setting cannot read front my protocol sending-flow. So you can test and find the fault function, then I can try and help you get it working well. Second is sending command have some differences, that's might be harder than point one, 'cause mine contoller flow is I'm observing by tracing the PC APP to contoller and using it. So if you can do the same thing, the all process of contorlling em-50 is 99% correct.

While connected controller by bluetooth by APP, you can press "LINK" and see which setting not get and change it by GUI, if setting value not your correct value, you can change it by APP GUI. If it not changed, please tell me, we can see how to slove it.
