Remote readings of battery voltage?

Winters here can be quite severe here. With terrible weather sometimes I pretty well stay in the warm bedroom. Would be nice to see battery voltage though.

And there are a lot RS485 remote meters (with lots of Volts/Amps/Hours) LCD displays for less than $50. I am surprised how much is out there... I just searched for "wireless voltmeter".
