Internal battery resistance does not change. The voltage on the battery increases as the battery charges so it requires more power to go from 90% to 100% than it does to go from 80% to 90%. A high internal resistance in not good because it limits the amount of power available as the battery discharges. Two batteries at 50%. The lower internal resistance battery will put out more amps at a given load than the high resistance battery.

I’m still waiting for Part 2 :C

No, you can't get 105 amps for one hour with a 105 Ah battery. In the United States, we use a 20 amp discharge rate. Under IDEAL CONDITIONS we get 105 ÷ 20 or 5.25 hours at 20 amps discharge.
