How to make your own Digital Dual Battery Volt Meter for less than $30

Ive spent a fair bit of time looking into Dual Battery Meters and all of them have either been horrifically overpriced or just plain ugly. Instead I went to Jaycar and raided the parts bin and made this for less than $30.

Here is the basic supplies needed:


* 1x 2 way Switch (to switch positive feeds from both batteries)
* 1x Jaycar Digital Voltage Gauge
* 2x Fuse Holders
* 2x 0.5 Amp Fuse Holders
* 3-4 metres (approx) of 1.5mm Positive and Negative stranded wire.


The final look:



Whats involved:

Pretty simple, run a positive and negative feed from 1 battery, and a positive feed from the second battery. Connect either positive wires to the outside poles of the switch. Connect the middle pole of the switch to the positive input of the volt meter, and the negative run from one battery to the negative input for the volt meter.

I used a piece of really strong bunnings double sided tape to hold the volt metre to the dash and it works a treat. Enjoy!!!

Ryzz which meter did you use as not all meters can use the same supply for the meter and the reading that's being taken ?

I've only just come across thread after I've installed my setup. The little switch switches between batteries - left (Main) // Right (Aux) // Middle (Off). Switch and Box from Jaycar, the Blue Digital Voltmeter off eBay.
Excuse the UHF... I installed the Simoco UHF under the Drivers seat (Velco), just got to find a place for the hand piece.....

here's a couple pics of my rough setup:

I can't remember the exact model number, but from memory the brand was digitech, if I can find the receipt I'll post the model.it only had to wires so no artiste supply/monitor input. Hope this helps
