Lots is good, but they are expensive.
They are also lacking the armor ability, so they are NOT hit first.

What they will do is give you a good chance of not losing other important components, like lifesupport.
If you have, say a 30 component cruiser, and you add 70 BTG, you can expect that less than half of the weapon impacts that get through both your shields and armor will actually cause important damage.
