Possible Mamba Monster/Max feature?

Patrick,

Just thinking out loud here.

You stated in a previous post that sometimes the ESC temperature monitor doesn't react fast enough (temp changes are fairly slow by nature) to prevent catastrophic failure.

So, would it be possible/advisable/practical to add in a feature that watches for drastic dips in voltage, something like 15% of the normal running voltage, and stops the ESC operation? A voltage dip that high lasting more than a few hundred ms could mean the batteries are not up to snuff and/or a problem where the ESC is about to burn up. Shutting the ESC down and throwing an error code would hopefully alert the user that something is wrong. Basically, have the ESC watch for abnormal running conditions where there is a large surge of current (which usually causes a drop in voltage). This is somewhat similar to the LVC operation, but instead of an absolute voltage cutoff value, it would be relative to the voltage at any given time to compensate for the changes in voltage during the battery cycle.

I know huge surges in current are possible at startup, so the dip would have to last for something like 0.25-0.5 second for the ESC to differentiate between normal operation and abnormal operation.

I'm just thinking of ways to limit collateral damage if an ESC is on its way out, a motor has a shorted phase, or the motor's magnet has blown apart. Just an extra layer of insurance.
