Advice on converting a 3,7V battery voltage into ≧ ±12V @ ±1A

Brad;
I remember the oldest camcorders (the ones which recorded on VHS tape) actually had 12V lead-gel cells.
Back in the mid-to-late 1980's

Heavy stuff!

But I believe that the broad approach, local distribution and regulation of power, is sound. One immediate advantage will be modularity and ease of maintenance. I do not think that the stated maximum power load (24W) will be continuous but the life time of the battery is an important factor. I have a door peep hole camera that is activated by motion sensor and is run by a 600mAH Li-ion battery that runs of a few hours (less than 24 hours). I have not changed the battery for months!!!

Actually it looks like the current requirement will be dropping, too what I can't be sure but I will look into it.

This supply is for the meter discussed in:
(I'm in the middle of writing a post there but I'll post it later, though you'll probably have seen it, the one about a LCRZ-meter)
