How can I check when my Energy Cells are full?

[Fantastic Chimni]

I'm trying to make a power station for my base and I cant seem to find a way to shut off my engines automatically when the Redstone energy cells fill up. Is there any way to have them send out a redstone current when they are full or when they are not full?

On a semi-related note, is there any documentation on how the new logic gates work? I got used to the old ones for setting up logic gated and redstone control rooms and i;m not quite sure how the new ones work and the wiki is still really bare.

There's a video on this page... http://minecraftbuildcraft.wikia.com/wiki/Gates

Gates will work for what you want. Attach them to a structure pipe on your energy cell, and set them to emit a signal when full.

there's a nice thread here that talks about this as well.
