Eric, I thought you perhaps noticed an audible difference under battery power compared with AC.

Glad to hear there's deep discharge protection and a low indicator.

I will be using the battery a lot. Does Axiom have any recommendations about extending battery charge/discharge cycles or preventing the battery capacity from being reduced? Should we limit charging to room temperatures or is it OK to charge the battery on a hot day outside under solar load?
