I need a 12 volt rechargeable battery pack for something I'm building for
work. Something using AA cells would be a decent size/capacity compromise.
The pack will be external to allow quick changing and will have a flying
lead connector. I'll need three to cover requirements and a charger which
can recharge in say four hours but have an automatic cutout if left on for
longer.

Obviously I can source them from RS etc, but wondered if there was perhaps
a model pack that would be better value?

Hi,

How about a couple of 6v packs?

Or maybe a DC-DC converter with 7.2v or 9.6v pack.

cheers,
