The HBridge is powered by the +V and GND from you battery. The HBridge GND must be tied to the controller GND. The HBridge V+ can be hooked to VCC on the controller or it can be from a separate motor battery.

and what does the word 'power supply is single ended' means?
That would be NO, unless your signal from the controller (Froward Control / Reverse Control) are also at 12 V when high. I am thinking that with this setup the HBridge V+ can not be greater then the controller VCC. One of the analog guys will speak up if this is wrong.
With this circuit, your logic must make it impossible to put a high in both imputs at the same time. - If they are both high then all 4 transistors will be on, and there will be a lot of current, heat and smoke
Also, the power supply must be protected against short circuits - Add a fuse in the bridge's +V lead.
