Braille Battery & E9X M3 Brakcet

Hey guys, I'm wondering about going this direction for my autox setup. Does anyone have advice or know which battery to use?

I'm stuck wondering if their 11lb or 15lb is enough CA for the car, because in autox you def start the car up over and over. I'm fine with charging the battery between events because that's not a big deal.

I'm not worried about starting the car with this battery in the winter as I'll put back the stock one.

Does anyone know how to "reprogram" the ecu for the correct battery settings?
I'm assuming I'll need a bt scan tool to do that and how? Thanks for the help.
