Hi everyone !

I am working on a simple robot project : I want to move heavy stuff with a robot.

The characteristics of the robot are :

- Capable of moving 10kg
- A speed of 3 to 5 km/h
- wheel size : 63mm
- 2 motors each driving a wheel

The problem is that I can't find a motor capable of moving a 10kg robot.

I have this engine but I find it too weak for my needs :

Do you have project that can help me in my research ? Or the ideal engine

Secondly, I have find a 12V Li-po battery, but I use a Dual motor controller and it says it make a voltage drop of about 2V. But I don't know if it's true.
This is my controller :

Should I use a 4*3.7V Li-po battery ? 


Thank you in advance for your help !

I hope I was clear enough...
