Lipo Confusion

[eyeayen]

Just getting back into this, never used Lipo before. Buying my first car soon with everything I need. ( Probably going ORCA speedo or maybe Fusion ? )

I've read some clubs require you to have a 'cut off' on the speed control to stop the lipo cells going to low.

Is this a standard thing ESC have on them or is this something I have to buy as an extra ? I'm only going to be running it for races and maybe testing at the same track so technically I shouldn't be running it long enough to take them that low ?
