A little over voltage is fine but During Regen if the batteries can't handle it Its going to about 3 times the rated voltage of the FETS in which case the very thin layer of Si is damaged and the FET will short out, usually just after it's called into action again (when you take off), once one goes then the rest are sure to follow. At least that has been my experience with overvoltage and mosfets.

It must be understood that common sense and caution are factors which cant be built into this product.
