RV Batteries - Lithium as Option
I've read enough to develop questions I can't seem to find the answers to, so I'm here once more to soak it in.
I've had some concerns that the current and original batteries on my Class A might need replacement, even though they're about 3 years old, in part due to my lack of experience in depleting voltage to a point that running off the batteries inevitably runs out of power in the wee hours, with the meters showing me LOW VOLTAGE somewhere in the 11's, so, I'm considering Lithium.
I also have 480 watts of Zamp solar, maxxed out at 26.1 Amps, along with a separate portable 120 watt panel, and a Zamp Solar 30A Controller. Am considering adding another panel or two -if I can find a place to mount them, and realize I'd need a new Controller, maybe 45-60 Amps, MPPT, and should be more than sufficient.
Having recently retired, I now have time for some extended travel, and boondocking will almost certainly be a part of that. I'm looking forward to getting off grid periodically, so power resources are key.
I'm aware of the cost, and believe that this is the most economical long-term approach to my power systems. So I'm willing to consider Lithium, and need some answers to fill in a few holes...
My rig came with 4-12V batteries, each 115 min at 75 Amps, 220 AH@ 20Hr.
If I connect Lithium in parallel, do I double available amps?
Are Lithium's all 12V, and if so, would I need only two to replace what I currently have?
What changes, if any, must I make to existing systems in order to accommodate Lithium batteries?
