Tesla Motors’ Devastating Design Problem

I've been flying li-poly electric planes for years. Every battery controller has low voltage cutoff circuit that will not allow the batteries to be discharged to a damaging level. No engineering team in their right mind would not use the relatively inexpensive technology to protect the batteries.
To add to that, charging circuits that charge each cell only to its maximum safe potential increase expected life to their theoretical maximum.
Over the last year or so the maximum discharge rate of the batteries has more than doubled without damaging the cells.

The developments in battery technology and the existence of cost effective power systems preclude damage to the batteries by anything other than physical damage.
