i have two motors one 12V 10A, another one 40V 10A. Can anyone recommend me how do i split one power unit to both motors if i had one 40V 10Ah? what happens if the Ah for the battery is more than 10Ah(40V 20Ah)?

Your battery will have to put out more than 520W to compensate for the losses in your DC/DC conversion, but yes, a hefty DC/DC converter would work for this. Maybe you could connect the motors in series? The current flowing through them will be the same, but the voltage dropped across each motor will be different and dependant on any instantaneous mechanical loading you have, but as long as everything stays within nominal limits, you'll be fine.

Use a DC to DC converter. Your battery has to be able to supply 520 Watts (120 for the 12 V motor and 400 for the 40 V motor). A 12 V 44 AH battery will last around one hour.
The easiest way would be to use a 12V battery and a 12V to 40V DC to DC converter. The converter has an inverter. The output of the inverter is rectified and filtered back to dc.
