1. I have a 200aH LiFePO4 battery as my main in my fifth wheel. All properly setups and running fine. Can I add 2 Ever Start 29DC batteries but use a cutoff switch with a 1-2-OFF position? Number 1 would be the LiFePO4 battery and number 2 would be the FLA batteries? They would never be joined that way.
2. How can I power a charger (while on the road with no dc to dc charger(yet)) to the FLA batteries? Any suggestion as to equipment to use is appreciated.
Mike, shouldn’t the positive and negative connections to the serial/parallel banks come from opposite ends? With only two batteries it’s not as important but with more than that and wiring them as shown the last battery in the chain sees a slightly lower voltage, and probably ends up undercharged.
This is a technical schematic, not a wiring pictorial. But you are correct. For best charging balance all battery conductors should be as close to the same length as practical. I’ll make some drawings about this later.
When testing 6v GC batteries in a Coach, is it as simple as disconnecting the cable on each battery and taking a reading with a meter? What is considered too low of a reading? Looking for a friend
Hi Mike, got two questions for you.

I have heard you can add batteries to your 'collection' if they are Lithium and they are a year old or younger.
The jury is still out on that. I’m talking to a few Lithium battery designers with different opinions. I’ll update when I know more…
