Sorry to rain on your parade but you will only have ~75AH.
Series brings the voltage up but not the AH. That will be an average of all the batteries. To bring the AH up you will need more batts to parallel with the ones you have.
As a side note, be careful mixing different size batts, this creates heat and charging issues.
Awesome build, I've enjoyed following it !
