Served me pretty well until now!!!
I do understand batteries in Series vs in parallel. As for your comment AH dont change? yes they do!! The T105 has 225 of them. 8 T105's has 1800 of them. Thats a big change!!!, And I am not assuming that I can use 100% of the stored energy. I am well aware that I shouldn't draw below 48.4 volts, so thanks for assuming that i was assuming.
Also my uneducated common sense tells me that your not really wanting to help me, but rather to try and prove me wrong on every thing i say, and im not into that. Thats not why i posted on here!!!
I have all my parts already "PURCHASED" so i dont need stats or corrections, or different thing i should have bought... I simply want to no if there is any issues i may run into installing or building the setup I have? and to anyone that has done the 8 6volt battery upgrade with bigger controller on a stock motor, I am inquiring about any performance gains? Thank you again!!!!!

Contrary to your apparent belief, I really do want to help you. My intent wasn't to prove you wrong, it was to dispel false information and excessive expectations for future readers of this thread.
True, a T-105 is rated at 225AH at a 20 hour discharge rate. However, when connected in series the battery voltages add and the AH remain the same, so eight t-105 batteries connected in series produces a 48V - 225AH battery pack. See attached excerpt from the Trojan User's Guide explaining series, parallel and series/parallel configurations.
As for performance a six T-875 48V battery pack weighs 378 lbs and a eight T-105 48v battery pack weighs 496 lbs, so the latter has more range, but the cart performance (acceleration and maintaining speed going uphill) is less due to having the equivalent of an additional passenger (118 lb) onboard all the time.
