Hello everybody,

I have a set of battery, but I only one hooked up to the circuit, The
other one act as a backup. I want to implement an electronic unit that
will change (swap) the batteries.Therefore the wiring will need to be
changed. The circuit need to support 5amp of continuous current. Here
is what I want to implement.
from:
A to C
B to D

to:
A to D
B to C

Is it better to use a analogue or digital switching approach. I am
just worried that digital might take too much energy by keeping those
transistor or mosfet open and close.

You mean something like this? (view in fixed-width font, for example,
with Notepad)

+---+ +----+ +---+
|(+)|--switch A--| |--switch C--|(+)|
| | |Load| | |
| | | | | |
|(-)|--switch B--| |--switch D--| |
+---- +----+ +---+

Michael, This is basically what I want to do.
The battery will run a very small motor and a light.
