Hi
recently I asked for any experiences with a battery powered A100 system.
Now I can tell you it works nice and easy for non-V/Oct bound systems.
I built a 3HE system with
VCOs A110, A111
VCF A121
VCA A130
LFO A145
and two Theremincontrollers A178
Raw pictures from the system itself are here

Pictures from the action can be found here:

For the powersupply I used two panasonic plumbium accumulators 12V, 2Ah.
I could use the system for around two hours without any trouble, and the
accumulators seemed to be half filled still.
