I like the Display, you can see at what percentage your batteries are at, sweet.
Honestly cant give you a simple formula to work at coz formulas are never accurate, just too many variables to play with like your internal losses on the electronics, quality of electronics etc.
Simplest way is fully charge your rig, write down the time and yank the AC cord out of the wall socket.
Keep gaming, Netflixing etc until your battery indicator there hits the 50%.
Write time down again and do your maths. Plug AC cord back in and recharge.
My personal opinion is not go less than 25.4v across your bank, if it isnt enough time then get another 2x105aH and put them in series-parallel with your array.
Your system is designed to go to 25% battery or even 0% battery life but i would never in a million years do that to a lead acid battery. Only to lithium, but thats just me
