[_paralyzed_]

you've got it wrong radioman.

R/C esc's are quite sophisticated and do indeed have regenerative braking.

"Energy is neither created or destroyed" You can't just "shunt to ground" the multi kilowatt output of motor braking. THAT would blow the esc.

And that many watts of motor braking cannot be simply dissipated as heat.

The energy does indeed go back into the batteries. That is why a battery with a low internal resistance is so critical.

You seem to be making a lot of assumptions based on your prior electrical knowledge. I feel you should learn about the new technology before you claim to understand it.
