How far can I drive after "Check hybrid battery" notice

I'd love to hear from anyone who's driven a car after getting a "check hybrid battery" notice pop up.

A notice popped up out of the blue on my 2012 Prius C. It was the "Check Hybrid battery. Stop the car in a safe place immediately" notice (or something like that). The emergency auto people checked and the following came up:

Fault 3 Hybrid control
P0B47 Hybrid battery voltage sensor C circuit low

From my research so far, this means anything from cleaning/replacing sensor wires/connections to replacing the ECU/voltage sensor on the hybrid battery.

My question is - how far could I safely drive the car, if at all? My preferred service centre is 325 km away from where the car is now.
