Battery control module

I was disconnecting the battery and caused a short. Everything is dead - not power to anything.

I've looked at all the fuses in the engine bay fuse box. The ones in the box to the left of the main box - nothing untoward.

I am looking at the battery control module and wonder if something could have been damaged. Is it a sealed unit? What is inside?

Have missed anything? Are there more relays fuses elesewhere. So far i have seen the engine bay near the battery and in the glove box.
