Alright, that does make sense. Thanks for correcting me and clearing that up.
If the amperage was split between the two batteries you'd end up with the same amount of power with the 12V and 24V system which really doesn't make sense when you calculate power output in watts.
example:
parallel setup of 2 batteries: 100A @ 12V = 1200W
series setup of 2 batteries: 100A @ 24V = 2400W
Each battery in the series setup must support half that wattage. But each battery is only 12V. Therefore, you must pull 100A @ 12V to get 1200W which is half of the 2400W.
I hope that makes sense to others...
