VOTOL-EM-150s controller

[jeff-jordan]

For 100km/h you need about 7kW at the rear wheel
For 120Km/h you need 70% more power, which means >200A continous from the battery, bms and the controller.
And you need a higher KV which means less tourque or you need a higher Battery voltage to get more rpm.

From my observations, I can confirm this statement as far as possible.
The speed around 100 km/h is a pivotal one, because there the aerodynamic resistance really kicks in.
In fact, if you are riding in the slipstream behind a lorry, you don't even need the ~ 7kw to reach the 100 km/h, and yes: you can even run faster then (if the lorry does as well ).
You need to be aware of this phenomen, because if you think you can pass the lorry easily and leave the slipstream to overtake, you're in danger because your excess speed will drop drastically.

Btw.: yesterday, as I drove at the B45 (without any slipstream), I just reached the 100 km/h... and my coulomb-meter showed a current of 123 ampere and 76.5 volt battery voltage. so the power was just 9.4 kW.

Does anyone have this controller and does it have an alarm on the motorcycle?
My bike also has this Votol controller and I want to put one on it so that it makes noise and blocks the engine if someone tries to steal it.
Thanks.

Hello,

the VOTOL 150(s) has an anti theft wiring in the 8-pin-socket (5 pins active), which is open (without connector) on Your foto on page 1.

There are chineese anti theft alarm devices to connect to this wiring. May be this set fits:

My (alternative) fardriver controller does also have five (active) wires to connet an anti theft alarm device. (chineese standard?)

In this place?
My motorcycle does not have the wiring that goes in the red

Exactly, this is anti theft. The 16-pin connector in the middle is communication/swiching and the lower 6-pin ist motor-hall/temp.
You can order the wiring harnes of VOTOL Controller at the same shop:

ColorCode of the alarm wires:

Maybe, the alarm function has to be activated in the VOTOL-Software page 5 (port settings).

Ok, thanks.
