Is it imperative to have AGM batteries with a solar set-up? Why? Could you not just use 2 6v batteries (not AGM's)? Do they last longer? How much and are they really worth the price difference?
What do agm' s vent, what gas? They will be stored in an inside compartment. And yes we may use big draw items, hair dryers etc. Don't know yet how deep the compartment will be.
