If you are playing with DC power, I want to draw your attention to
a company which makes some useful gadgets.
For instance this one:
http://www.mini-box.com/OpenUPS2
I havn't tried it yet, but it looks like a very convenient module
for adding a small built-in UPS. (They have other products for
bigger batteries.)
This "ideal diode" looks very promising:
http://www.mini-box.com/Y-PWR-Hot-Swap-Load-Sharing-Controller
It is based on Linears LT4415:
http://www.linear.com/product/LTC4416
I don't have any experience with these particular two products (yet,
I just ordered them), but I have used a number of their PC-power-supply
products for years with no trouble.
My only complaint with this company is that their european distributors
seem to universally suck: Either they don't carry the parts I want,
their margin is unreasonable or they don't respond to email :-(

Never attribute to malice what can adequately be explained by incompetence.
