As I research features we might want in a B van, I am thinkimg that Lithium batteries might well be a desirable thing, but not sure that we need or want "Voltstart." Especially when I learned that it is an option priced in excess of $1800!
We don't have pets any more, and I don't foresee needing to run the AC any time we are away from the trailer.
What I am wondering is whether - without voltstart - it is possible to set up a simple voltage drop monitor with an audible alarm to tell me I need to run
the engine - or generator to recharge the batteries,
I gather Lithium batteries hold their voltage and can be discharged much deeper than AGM's, so I'm not sure how well a simple voltage monitor would work.
Would that be what triggers "Voltstart," or does it use some more sophisticated means to determine when to charge?
I was thinking about a simple device like this

You can set the alarm trigger voltage to whatever you like within range.
Any thoughts or advice?
