hrmm....to my knowledge u dont have to worry about un pluging the lipo in the box as there's nowhere for the power to go.....a Rx lipo...a little different...as its normally hooked up inline with a regulator...which can trickle power off...but a set of motor's.....i dont think so......i have never noticed any voltage drop or any Mah droppage over time....but i have only been runnin lipo in the box for a couple months now.
