Glad to help, I am not a professional, just love electric carts and I enjoy sharing my experiences and hearing others from TV. There are a lot of good sites, but I always find myself back at Trojan Battery Company (Maintenance page) for a reference. Once you get on that page, read through the related links. There are two that are pertinent to our current discussion.

This one talks about how deeply to discharge related to your 47 volt question.

On the following link pay special attention to the chart at the bottom.

As far as what do you have left when you at 48.4 volts? Your mileage will vary. I did a test last year on my pack and took the time to graph my results. Here is a long winded description of the test run Test run description

and here is the results which may answer your range question.
