Please NOTES :
You are going to purchase the Lowest Power Consumption Volt Meter on the Market.

The only LISTED ITEM compatible with 12v and 24v battery

These volt monitors are a great little device. They solve the need for a quick, easy to read display of battery voltage in a very clean, compact solution.
They feature a very useful momentary membrane switch, which lights up the display. The volt meter then cleverly turns itself off after a small period, which minimizes consumption. These are the most power-efficient volt meters we have seen on the market.

Installation:
Installation is simple: two wires as you would expect, Positive and Negative. Or you can have them connected to your ignition switch as indicated in the Installation Manual*

The body can be mounted either using the two screw mounts provided, or simply stuck on using a mounting tape solution, such as 3Ms VHB type tape.
The unit only weighs 10 grams.
Due to their compact size, they make a great solution for 4x4, caravans, campers, motor bikes, quad bikes, vintage cars, battery boxes, jump starter packs etc.
