Cool, your current sensor is quite similar to the one I was using. Just make sure to test it with a known load so you know you're getting accurate readings over time. Like I said, I had issues. I'm not an electronics guru. I do know a little programming so dealing with stuff like noise on lines is not easy for me.

I'd be interested to see how you plan on wiring / program the voltage monitoring to the arduino. Because your batteries are in series, each divider will add to the voltage of the previous batteries unless you have some way of getting around that. I assume you'll just have to compensate for the different voltage ranges in your code?
