If you're worried about over-draining your LiPo, you're not charging it enough, or running some puny undersized capacity LiPo. It's just that simple. Charge it more. Or if you want to physically run the battery to its limit, that's just dangerous and reckless.

I'll gladly take accidentally over-draining a $20 LiPo over destroying a $400 engine and potentially hurting someone.
I run the robotronic 1500 and yeah racing 1800. This is for HB D8 hara and D* Truggy. Last year I was running the 1700mah HPI nimh and yea I had one drain until I lost power and could not finish the main. Don't want that problem this year and if the new 1700 nimh drained during a main, I could see that happening with a 1800mah lipo and POOF. Mind you I am running Savox HV servos.

This is a great! This one I could find with decent reviews... but may be a little too big.

Switch to a Life battery is a good option I didn't see in this thread. Sure the voltage is a touch lower than straight Lipo but that's really not a big deal. No worries about running it too low because it can handle very low voltage that would make the servo's noticably slow and easy to see\feel. 1700mah can be had quite cheaply from Hobbyking or a little more at Amain.

If you run a lipo cut-off you need to run a throttle return spring so that in the event that you have a low voltage situation and the switch cuts the power, the throttle return spring will close the throttle.

I run a throttle return spring regardless of the type of battery in use to insure that my car engine will return to idle speed if something goes wrong.
