Help with my new Front Wheel Motor

Hi Guys


I have Purchased a Front hub motor for my new ebike project and would like some feedback if you would be so kind on my motor.


I have lots of RC batterys which are 7.2v 3.0ah which I will be using along with my 12fet lyon controller.


I have attached a few pictures'


What you think Guys ?

From the sound of the setup you will need at least 24v for the controller

You have stated that you have a bunch of 7.2v batteries

I assume by this voltage notation that you have Nimh batteries (1.2v cells in 6 cell packs)

This type of setup is not optimal but could be used

At full charge, NIMH cells read about 1.45v per cell which would give you 8.7v per pack

This means at full charge, 3 packs in series would give you 26.1v which would meet the requirements for a 24v setup

The next issue you have is capacity

3,000mAh is very low - Most people will run at least 10Ah or 10,000mAh - for your battery type this means you would need 3 sets of 3 batteries for 26.1v 9,000mAh or 3 sets of 4 batteries for 26.1v 12,000mAh

For testing purposes, the 9,000mAh will do

This means you take 3 batteries, connect them in series - 3 times

Leaving you with 3 different groups of 3 batteries at 26.1v (fully charged)

Then you connect these batteries in a parallel harness to combine the mAh to give you 9,000mAh

Then connect this to the controller

(depending on how it is setup, it may need to be programmed for a 24v setup)


-I too am from the RC world, I converted a 8ight-t nitro truggy to brushless electric, as well as many others
-If you are comfortable with RC setups, lipo is far more powerful

Let me know if I can help

Hope this was helpful

God Bless

That is awesome thanks for the really useful information .

The reason I'm using the Rc battery's is because I just have them for my disposal so may as well use them.

I will keep you inform of my progress

Absolutely, use them : )

Because Nimh have moderate voltage drop you may find your throttle cutting out due to the LVC

Let me know what I can do to help : )

You can see my build in my signature that shows a similar build but instead of Nimh I am using Lipos
