A golf cart does not operate the same way as a car, for example the golf cart engine stops when you stop the cart, and starts again when you press the accelerator. In order to do this you need a functional battery ALL THE TIME. So you would need to leave the powerbank connected to the battery, and pray it would not be damaged when the golf cart is moving and trying to charge the battery.
If you are having battery problems, have the battery tested and replaced if necessary. I think the powerbank is a dangerous option.
