Thanks for the info Mainey.
Just to add for Dan, the battery place also advised of a meter, I did get that, and it is on the battery. Yes, very very good $40 investment to tell what charge the battery is at. I found what I have now, really powered my needs easily, but thanks for the heads up on the anderson plug etc. Yes agree, a sine wave inverter is best by far... bit dearer, but well worth.
