[QUOTE=snoopyrc;8456136]A BEC is a battery eliminator circuit. Its an old feature on speed controllers so that they will power the receiver and servo thus eliminating the need for a separate receiver pack. It has nothing to do with the lipo cut off.
If you have a lipo battery and charger the only other thing you need is to be careful. A lipo battery is nice and safe unless it is handled improperly and then it is a fire hazzard. If you run it down too far then it will do something called "puffing" you can tell if your lipo is puffed because it will swell up like its allergic. If it swells up its already ruined and likely to burn your house down. If it gets punctured it will burst into flames.
Ok a safe lipo charger will keep your battery from over charging and exploding, but you can also discharge the battery too far. Good brushless speed controllers usually have a lipo cutoff that will keep this from happening. If you dont have one just make sure that you dont run your RC model for too long.
thank you for that
because im just beginning out racing, and will probily put drift wheels on it to play around with mates iswell. iv been looking at LRP8063 ESC IPC SR Digital, LRP ESC: F1 Reverse Digital, LRP ESC: F1 Reverse Digital and the LRP A1 Pro automatic speed control there all around the $80-$150 mark.i guess its safer for me to run ni-mh with what sort of esc would you reccomend?
