Change ESC cutoff rate

Using Arduino Motors, Mechanics, Power and CNC

Hi everyone, I ma making a rc airplane, with has 2 ESCs. I want to change the cutoff rate to 3.4v per cell, so that the electrodes do not degrade. 30A BLDC ESC - Brushless Motor Speed Controller buy online at Low Price in India - ElectronicsComp.com
The default is 2.9

Your idea, to raise the cut off level is really good. However You need to get hold of the technical data sheets. Nobody can guess what's hidden in that yellow shrink sock.

Its actually written in the website from where i bought it

Schematics would be needed to make the change You want. Users data don't tell anything useful.

meaning??

That ESC is not programmable. So you can't change the Low Voltage Cutoff without reprogramming or replacing its internal microcontroller. And from the level of questions you're asking that's not something you will be able to do.
