I have the older Emaxx and know there is no voltage cutoff - mine will let you run until it just slowly grinds to a halt. The newer Emaxx, 3905 says it is not lipo compatible and states "The EVX-2 is not equipped with low voltage detection" on page 12, lower corner in a warning so its no different than the older one as far as having a cutoff.

Hope nobody read my dumb*ss idea - def wouldn't work. Still don't know how to wire an lvc for an emaxx to use lipo. May have to settle for one batt - I know one batt does more than other (supplies rx and servos) cause I always have one (same one) thats takes more on charge - maybe put lvc on this one and setup with 6.2-6.4v as safety margin? I'm not cool with risking over $200 in lipos on a maybe though, guess thats why I'm charging my NiMHs.
