S866 Display & components

[UrbanPuma]

Is there a specific throttle that has to be used with the S866 display and Brainpower controller?

Thanks in advance

All throttles work the same. the controller can't tell the difference from one to another. The only thing you have to do is connect the three wires in the right sequence.

Great thanks

Hi Saneagle, I've just noticed the shop fitted a Brainpower 36/48v Power: 250/350watts controller to my bike, but my battery and previous controllers were all 24v. I would have thought I needed 24v. Will this cause an issue with the bike, which is a 180 or 200w motor?

My battery is 24v - 17.5 ah.

Advice appreciated.

Thanks

If you have 36v/48v dual voltage controller then a 24v battery won't work .
The max charge for 24v is 29.4v which is lower then the 30v lvc of most 36v controllers , with some controllers it may work for a few minutes but the voltage will soon be too low.

It appears the shop /LBS doesn't have much clue if the voltages are mismatched.

Thanks, would it just cut out and will it harm the motor? I road tested the bike for a few minutes and started it up at home but not been on a long ride. It works and is very nippy, but I don't want to damage my bike with the wrong components. What do you advise Nealh?

If the bike has a 36v/48v controller, either it wouldn't work at all 9r it would switch off after a couple of miles. If your bike doesn't cut off, the controller is suitable.

Ok, thanks Saneagle. I will test it out next week. I did notice the display switches off when I stop. Is that just a programming thing then to set display to stay on longer?

Yes. It's sleep mode. Most controllers have it. Some have a setting to adjust the time before it switches off, or you can disable it.

Charge the battery fully if 24v it will charge to 29.4v, then go for a ride very locally not straying to far from your house. I can't really see you will go to far may a mile or two before it conks outs if the controller is 36v rated as the controller LVC will kick in and cut battery power.

What does the battery level meter on the display show with afully charged battery ?

 

[Nealh]

No damage will occur in this case.

Hi guys,

I've just checked the setting and sleep mode was already set to 10-mins, so the bike was shutting down each time I stopped at a junction. Is it correct to assume now that the controller is shutting down due to incompatibility?

Battery shows 27.6v on the display which seems accurate to me

In that case your bike theoretically shouldn't work unless the controller label is wrong or the controller is actually a 24v controller.

Something doesn't add up !!!
A 36v controller shouldn't work at 27.6v.

Ok, I'm going to check with the shop. I saw somewhere that some of these Brainpower controllers can be set to different voltages but they are normally labeled 24/36/48. In the settings they have set 24v, so I don't know if this controller accepts all three voltages.

 

[UrbanPuma]

The shop said there will be no problems, stating 24v would be too weak and that they put the extra power so that it works. All my controllers have been 24v though and the bike worked to my satisfaction.

Not sure whether to still do the test run.

I have some 24v controllers on order and I'm planning to swap it over, as I don't want anything to damage my motor.

The shutting down is incorrect. it shouldn't do that unless you stop for 10 minutes. Do you have speed displayed on your LCD and does it work properly?

I thought it didn't seem right. The speed was in km (I prefer miles), but I couldn't make head nor tail of it so I would say it didn't seem right. I'm away from the bike for a few days, but will check next week as I set it to miles earlier as well as the wheel size.
