Argument thread: Low specc batteries don't kill ESC's. Or do they?

[radioman193]

if the voltage was to "sag" it would be like runing on a low batt ..

so under that
that would be every time your battery went low your esc would smoke.
I don't see this.

i have seen ALOT of esc's go bad in plenty of ways and for plenty of reasons.

but in all my time in electronics and teaching electronics I My self have NEVER seen low voltage make a device fail that catastrophiclly with total distruction
but low voltage can damage the low voltage regulator.

The first video by the amount of smoke it was NOT the battery it was the drive fet's that Failed that is The Only way you will get that mutch smoke and fire.
as 12 to 24 fet's fail but most of the time only 2 to 4 will "give up the ghost" .

and if a servo kills a esc it would not smoke that bad as there is ONLY 1 to 3 regulators and seperate from the motor drive fet's that is used for the servo drive inside the esc and 1 small transistor dont have the mas or material to produse that mutch Venting smoke and or fire.
and not all three will go as the design for a 3 stage regulator only the first or the last one will go.

we use to burn fet's and older style regulators up for fun in electronics class my students got a big kick out of it
and were learning at the same time.
