This whole question is why I haven't changed batteries yet.
The difference in cost between 4 good L16 AGM's, and 400ah of Lithium, is near moot at this point.
When you rewire the batteries and inverters and move them inside to the rear of the basement a Classic can also have warm batteries.
Agree with you there on a switch to lithium especially on a Vegatouch coach. They are not a set and forget as the Vegatouch does not allow for proper programming or setup.
