Julian,

This is not something I know anything about but you might want to
consider some kind of smoothing / protection circuitry between the
batteries and your A100 just in case.

Subject: 1 Battery powered a100 How feasible


Heres me thinking again about how i can get the a100 more
portable.

I was just looking into some other electronics, and was
considering a couple
of 12v sealed lead acid batteries to power it. Then i looked at
my a100...

Say a couple of 7Ah batteries. Now, im presuming that the 600mA
psu's in
the G6 racks are 600mA on each rail (and not 300 ). On paper
then, the
batteries look as if theye last over 10 hours at a 600mA drain.

Even half that would probably be ample for me though. And, of
course this
is looking at a G6 rack running at full capacity.

I think that the sealed lead acid are fairly constant voltage,
only dropping
off sharply at the end of their capacity, which would be ideal.
The also
have the big advantage of being able to be put on charge / float
at any
state of charge (with a 3 stage charger), so you can be sure
that, when you
want to use them, the batteries have a full level of charge.

Has anyone thought along these paths before What sort of
conclusions did
you reach

Cheers, julian
