Sure I'm no expert but it's just stuff I've been learning since doing my own basic one like yours.Thanks for the useful tips, much appreciate it

Okay so you've got them setup in parallel, which means you are getting 24v but still 104Ah. Which means you only ever want them to get to around 52Ah remaining on the battery. So you'd be able to use about 1248watts (Ah*v) that's you're total wattage you'd need to bring the battery to 50% which is the recommended drain.
That would mean if you were powering a TV and a decoder you'd probably get 6 to 7 hours (150watts +-). So if you drain it to 50% you'd need to charge back 1248watts during the day, so you'd need a 200W+ solar panel to replace that in about 8 hours or so.
I did yes, parallel doubles the ah while series doubles the voltage.I think you meant to say connected in series, double the voltage, same current/capacity
I did yes, parallel doubles the ah while series doubles the voltage.
Two batteries in series, voltage adds up and Ah remains the same, two batteries in parallel, voltage remains the same and Ah adds up.I've got one of these and there is a switch on the back that is set to 10A charging as you should charge the battery at 10% of the Ah rating so as you have two batteries in parallel it is 104aH.
