I got a battery voltage switch from AOB eBay. Sits beside the dual battery voltmeter and Dual 2.1a USB outlets from solidkit. I powered the USB from the aux battery so it's always got power.
I connected the negatives for the voltmeter and USB ports and used a relay controlled by the AOB push button switch to turn all of it off as I don't like the constant glow of the LEDs at night.
