Unfortunately the ThunderBorg has a maximum voltage input of 35 V. Going above that exceeds the safe operation limits of some of the components on the board :(
If you can find a suitable step-down voltage converter which is able to handle the full current draw of the board and motors at a 30V output then that will work fine :)
I would recommend one capable of 12A or higher output to cover the maximum motor and 5V power draw from the ThunderBorg.
I believe these motors can draw too much current for the ThunderBorg :(
A quick search on Google lead me to this table:
It lists the rated current for the 12V 322RPM motor as 4.3A.
While this might sound fine, it means that the motor draws that much current when it is delivering maximum power. Unfortunately this is not the highest current the motor can draw, which is likely to be much higher (double or more). This worst case current is known as the "stall current" and is the current drawn when the motor is unable to move.
My guess is that one of the motors tried to draw too much current too quickly, causing the ThunderBorg to fail. While fuses are a good safety measure they do not protect against short spikes in current. There is a good description of how a fuse works here: http://www.my-car-computer.com/auto-fuses.html
I think Diablo would be a better fit for your robot given the motors and battery setup you have been discussing. It will handle much higher currents than the ThunderBorg and it can be used with a 36V battery setup.

Stepdown
Is it possible with a Stepdown converter to make it 30 volts?

Max input
Is the max input of the thunderborg 10 amps?

ThunderBorg current
The maximum output of the ThunderBorg is 5 amps per motor and 1.5 amps at 5 volts for powering the Raspberry Pi.
As long as the input can supply at least 11.5 amps it should be enough for the ThunderBorg to supply its maximum output.

Fuse
Thanks, i want to put a fuse in the input voltage, is a 10 amp fuse good?

Fuse
You want a little higher to cover the extra current draw from the 5V DC/DC on the ThunderBorg as well. I would recommend a 11 or 12 A fuse.

Thunderborg broken
Hello, today i was testing my robot but i burned my thunderborg, there is a 10 amps car fuse before the input, do u know How this is possible?

Many thanks, so the amperage of the motors is to high. Is it possible to put 1 motor on 2 outputs of the thunderborg?

Shipping times.
The estimated delivery will depend on which shipping service you choose. See https://www.piborg.org/piborg-delivery-information for more details.
The fastest option would be DHL Economy Select, which has a 1-4 working days estimated delivery for Europe.

Diablo and Pi Zero
Yes, the Diablo will work with a Raspberry Pi Zero :)
You will need to attach pins to the GPIO so you can plug the 3-pin cables in.
