Volt/Amp meter on 12v charging system

[oxydog]

To add to my question about PWM controllers and 7Ah batteries, another question:

Has anyone successfully added a combination Volt/Ampere meter to their solar charge setup?

I'm considering getting one of these


and build it into one of these


then make a cable using this

to connect the battery buddy to my charge controller.

Any flaws or caveats on my design?

PS. Thanks to https://www.lumenoled.co.za/ and https://4x4direct.co.za/ for the use of your images.

I think Pieter sells this type of thing at 4x4 Direct...

Correct, that's why I thanked him in my post for the use of their images!

I have installed the identical Amp/volt meters on my system. If you keep it on it will drain you battery within a week. The LED screen consumes a significant amount of power during 24 hrs. I verified this by checking the mA drawn by the meters from the battery and found that this is the main reason why my batteries ran down within 10 days without any external load. Wire it so that you have a little button switch so that you only check it when you want to know the Volts/Amps.

Thanks Pieter, that makes sense! My idea was to only plug it in when I wanted to read the values.
