That cable you broke might be the parking brake. (I have no VW experience, just a guess!)
Sure you can run everything off just a battery. That's a very simple way of doing it. Just think about what happens to your headlights in a gas car when you turn the engine off - your lights stay on (not as bright though) and if you leave them on long enough, the battery dies. But you could leave them on for quite some time.
Just make sure to always recharge your battery right away!!! And use a 12V boat battery, not a car battery. (Looks like yours is a 12V deep cycle, so good.)
If you want to get fancy, you need a DC to DC converter. That will take your full main battery pack voltage and electronically drop it down to somewhere in the neighborhood of 12.8-13.8 volts to run all your electrics.
Ideally, a DC/DC converter that constantly tops off an accessory battery would be the best.
Look for them on Ebay or EV supplier's web pages.
