Hobbyking ESC Programmer cutoff 3.2V/cell?

[xray328]

Hey guys, I was looking at this:

http://www.hobbyking.com/hobbyking/store/__17204__HobbyKing_ESC_Programming_Card.html

Am I correct in seeing that the highest cutoff is 3.2V/cell? I don't know that'd I'd wanna run my packs down that low.

Shows 2.8V/cell also available?

You don't.

Never use your ESC's LVC as a "time to land" indicator. It's sole purpose in life is to prevent catastrophic ESC failure from brownout, not to prevent your batteries from being over discharged.

Use a flight timer (in most mid and high range radios), or a voltage alarm to gage "time to land".at $3-5 each, a battery alarm is a CHEAP but reliable way to go.

In Plush ESCs allways set the cut-off the the highest.. i made the mistake of setting it to low many years ago and it ruinned a couple LiPos


As Crafty says its better to not let it cut-off as that usually means you went bellow the last 10% wich is not good for long term LiPo performance..

How to know when? well thats the trick... some use a Lipo checker with beeper.. some clock their flights (easier to do with helicopters and multicopters or 3D planes) , some use telemetry (more expensive option).

Ideally you should have at least 3,65 to 3,7V per cell left after landing
