What is this BS Castle is feeding this customer?

To answer the question of why don’t NiMh batteries damage the ESC is the fact that these cells voltage drop quickly under load then climb back. The drop in voltage protects the system from the motor pulling too much amperage and creating too much ripple current.

Is this means this bec problem in MMM just with lipo?
I don't have lipo I will run 16 nimh cells until i buy A123 that recommended by cc.. so I will be in safe side with nimh?
