I have a Roadtrek Adventurous CS with an unusual battery bank setup. There are two banks of 6V AGM batteries, one set up for 24V and the other as 12V. They each have a separate solar charge controller and they are linked through a Cooper Bussmann battery balancer/equalizer.
Do I need two BMV-712 monitors (one for each bank)? Or can I set up one as the main monitor and the other as a second battery? As they are connected through the battery balancer, will that confuse the capacity calculation?
If I set it up as a second battery, where in the parallel series of batteries does the secondary monitor connect? (I'm guessing to the most positive battery end of the parallel series.) And is there a preference to use the 24V (which powers the AC) or 12V (which powers the all the other accessories) as the primary battery?
I'm attaching an image that was shown as an answer to another question because it shows both systems that are present (although I think that there are 6 batteries in the 12V bank).
Thanks for any advice you can provide!
