Please help my Arrma Nero ESC is allowing my batteries to drain flat and I cant see in the manual how to set the battery cut of limit. My onyx batteries have swollen to twice the size no good. Any advice would be sweet
@Cammas try doing a factory reset on your ESC.

To reset the ESC to factory default settings connect a battery, turn the transmitter on and then turn the car on. Press and hold the set button for 4 seconds and release. The Red and Green lights will flash simultaneously to show you have reset. Switch the ESC off and factory reset is complete

It also doesn't hurt to get yourself a LiPo low voltage alarm. If the reset doesn't fix it then contact support to get the ESC replaced.
Will do cheers for the help mate. U think they will replace the batteries too ha ha.
