You have the numbers right there for the batteries plus batteries (thats what I'm running in the Paseo, a group 24). Lets look at the group 24 for example. It is rated for 150 minutes at 23A. 23A is .3C for a 75Ah batter. C rating will allow you to more easily compare to other battery sizes. So, you get 23A for 150 minutes. 150 minutes is 2.5 hrs. So, 2.5 * 23A = 57.5Ah of capacity @ 23A discharge. So, you only get 76.6% of the rated battery capacity at a .3C discharge rate. You can probably use this as a general rule but I'm sure it will differ from battery to battery. I know of no chart that will tell you the losses at different discharge rates. So, you can very easily imagine that "125Ah" battery from walmart is actually way lower at any significant rate of discharge. If it were just between the walmart and batteries plus batteries I'd definitely go for the batteries plus batteries.
