Now, that said, ANY battery that is pushed beyond its capabilities can damage an ESC.

Let me say that again:

ANY BATTERY THAT IS PUSHED BEYOND ITS CAPABILITIES CAN DAMAGE AN ESC.

AS CAN BAD CONNECTORS, BAD WIRING, AND BAD SOLDER JOINTS.


We have gotten so oblivious to the fact that we are harnessing thousands of watts in these setups -- any problems in the system can cause problems with other components in the system very quickly.

So we must be VERY careful NOT to push batteries harder than they can handle.
The very same is true of Motors -- and people seem to accept the fact that certain motors can only be pushed to a certain point before they fail.

Why do the same people not understand that a battery pushed beyond its capabilities can damage the ESC?

The ESC relies on the battery to both SOURCE high currents without significant voltage drops, and to SINK high currents without significant voltage rise. If the battery cannot hold the bus voltages within a reasonable voltage, then the setup is PUSHING THE BATTERY TOO HARD.
A battery needs to have the ability to sink braking energy during hard braking, and take that energy back as charge energy. If the battery can't take the energy back quick enough, the voltage on the bus will rise, and eventually it could get high enough to damage the ESC. We do bus voltage monitoring on the Mamba Monster, but if the battery is REALLY bad, the voltage can rise faster than the MMM can respond to it.

It all comes down to this: Don't push any parts in your system beyond what they can REALISTICALLY take. This includes motors, batteries and the ESC.

Just as some motors are better than others, some batteries are better than others. You can't expect a $25.00 Chinese motor and a $250.00 Neu motor to perform on the same level. Same goes for Lipos. There are applications where cheap lipos and cheap motors WORK JUST FINE -- but there are other applications where they may perform below par.
