Your going to get
https://bigbattery.com/products/48v-...id=ButtonsCamp with this Honey Badger 2X 56AH (As it does state the spec's for a single battery) a Max Continous current of 126amps and a max peak of (126x2)=252amps for 6 seconds.
It's really going to depend upon what your cart demands in the conditions that you drive. You don't mention if you can hook up a laptop with software that will acquire the amp draw you are using while driving your "usual" routines with the cart.
That would be very helpful to determine if this Honey Badger setup would handle your demands.
To me, even driving "mildly" you would be close to the edge of what the pack can do. But again, it may very well do you fine......but if you can get the amp draw you are using now....that would tell you the real story.
