all i can say

Is do testing and you will see the esc has 0 output under breaking.
and look at how the voltage is sent to the motor under breaking.

Under realworld bench testing.
just test a few esc/motor combos on the bench.

I need not say more on this as the proof is easy to find
and dont Overthink and make it harder than it is.

and remember this just because a motor runs on just say 6v @ 3 amps
thats not saying that it will OUTPUT 6v @ 3a as a Generator cause it wont.
so this blows away the number tossing game out the window.

there just might be Some or a few Rc Brushless esc's that do utilise regernerative breaking but i myself have not found one.

just do some Simple testing that others and i can do to see .......
And if i am found Wrong i will drop off ALL Rc forums completely never to post again .
