finally figured out how to get regen brake using the low-brake wire (gray/black) momentary switch to ground (black wire)

this controller is such a pain. documentation sucks

Yes, we use it on our electric gokart. Unfortunately only I/o

Finally hit the track with the Votol / qs combo. It was working very well. So much fun. https://youtu.be/B4VQ5DQ9LHo Looks awesome!! Currently on the fence myself between an EM150, Sabvoton 72150 and Kelly 7245H for my Super Soco TS with a QS 273 v3 4KW hubmotor and QS just recommened me EM150 henc...

It’s temp coefficient (TC) found in hidden/calibration settings. Haven’t tried them yet but there’s a description earlier in the thread how to get into this menu

Thank you Lars

Hi all, a little important update regarding Votol EM-150s (first gen) Now it goes better :) https://youtu.be/Wjo0IalwELQ Many thanks to Bartosh, without him this wouldn't be possible :bigthumb: Do not try this if you don't have spare controller, battery and bike For now following mods have been mad...

Yes, I’ve had my controller at 50V undervoltage setting when i tried to find root cause to cutouts i had at the time. thanks! finally got my controller. seems to accept 50v but i hope there's no weird LVC issues at those low voltages it's annoying that it's in park mode out of the box :roll: so i h...

But your em150 is still running with shunt mod. ?

Yep, and it still suck https://youtu.be/X-AoNunrhw4 (there is battery current on small display)

But is shunt mod. Still Better than without ?

Folks, are you ready for Votol EM-150-2 ? :lol: viber_image_2020-04-13_13-56-44.jpg viber_image_2020-04-13_13-56-43.png BTW, EM-200 died completely and no possibility to order another one, since "we think the hardware of original EM200 has some problems, not only your customer has such issue" But y...

Yes.. but i´m only talking theoretical here.... Is it right that my CC/Cv charger, lower the charge amp when close to end voltage ?? (4.20v pr. cell) Or is it the BMS that does it... Technically it is the charger that lowers the current. However the charger doesn't actively taper off the current, t...

No you need to charge at 4.05V at a minimum to get any decent range. 4.10 or 4.15 are still conducive to longevity. 3.5V is below where you should be stopping in effect empty.

Question about charging At the moment I have a 20s Li-ion battery, I am using the JBD Bluetooth BMS together with, it is working perfect. I am using this charger : https://www.aliexpress.com/item/32781966303.html?spm=a2g0o.productlist.0.0.484656ddXWUE1z&algo_pvid=5f559d45-073f-456b-a834-989103cf018e...

I just got my em150sp and qs138 motor connected to the software. Here is a pic of my throttle settings. when I twist throttle the motor doesn't move until about 1/4 turn of throttle. Is there any adjustment so it is more sensitive? and how do I know that it recognizes what full throttle is when it ...

Same for me. Have the 150sp, but in the software , it set as em100 ok then no worries, I just read at beginning of this thread that all that is important is the phase angle and the poles for the manufacture to set up for you motor before they send out then all rest are up to you to change, like bus...

On another node.... I was out testing a new motor pulley on my gokart today, with the votol/QS combo. A friend have made me a custom 24T and 26T motor pulley :-) The 24T is spot on for me, no more belt skipping, that I had with the original 22T, and still lot of torque. BUT I think I did experience ...

If its the Sp version, remember to tick "Can enabled" and power the controller from the battery. Its the same error both ways and I have the 82.6v to the grey and purple Elock wire. Then try reading the manuel. It sounds like you have wrong driver for the usb tool. So this controller can only be st...

Check the display page in the gui, to se if its in Park mode. If it is, search this thread to get the solution. The software won't connect to the controller I'm getting that error. open error.jpg If its the Sp version, remember to tick "Can enabled" and power the controller from the battery. Its th...

Hi Guys i just wired up or thought I did a EM 150sp and I can't for the life of me get it to turn on. What connections are required to get it to turn on? Are the Alarm connections required to turn the unit on? e-Lock is connected to the battery directly. Check the display page in the gui, to se if ...

im about to do a test run on my setup, 138 motor and em150sp controller. do I need a switch for the 3 speed functions? what if I just want it in the best performance mode all the time, would that be sport mode? and do I need any type of switch for that or can It stay on every time the unit is power...

Thought that so yes i ticked high gear but made no diffrence.

Does the software show you that you are in High mode ??

You are still in "mid." Speed..... Try putting it in High or Sport mode...

finally had a chance to test Votol with shunt-mod, folks it worth it. (1:8.2 reduction ratio) no stuck in climbs, no power loss, crazy throttle response. photo_2020-03-09_19-05-29.jpg Video soon... Woooow. Tell more :bigthumb: Are you on 20s btw. ? 22s Cool, and no problems with that higher voltage...
