Well first, you only want to fully charge a battery if you intend to use it that day. Otherwise keep your battery at a storage voltage of around 3.8v per cell. Your charger should have a storage function. There is nothing wrong with running the lipo for 5 minutes, then charging it back up for another run though.
The voltage cutoff is there for a reason, it tells you when to stop driving by limiting throttle below 50%. So no need to stop driving before you hit the cutoff.
