Yes you can tap the BATT post for a power supply for the fan or better yet the HOT side of your starter solenoid. Reason being: That terminal and wiring connected to it is usually unprotected with a fuse.
You want your fan to come on when you park the car after a ride due to “heat soak” so running full time power to the fan (via a relay) is the best option and use a temperature activated switch in the radiator or coolant line which interrupts a ground circuit, which triggers a relay to cycle the power to the fan on and off. If you wire it this way DO NOT introduce any kind of “+” source to this ground circuit of the relay or you will fry everything. (NO indicator light)
