HI,
I build this little battery monitor for the camping guys here by us to give a bit of info on how much energy is used and replaced and time left on a battery.
Have a look and maybe someone will be able to use it.
Link to all the files and some steps below:
And some discussions on it on our 4x4 Forum
With a bit of youtube for info and demo - some of the videos might be a bit dated as the revision of the codes changed.
Video added for menu and other functions-Partially v7.6
And here is v7.7 in action.
Here is a video of V7.9 of code.
