Re: [CAD_CAM_EDM_DRO] Digital camera battery pack

Hello Jerry

I tested the output of the mains adapter, which was exactly 6.5 volts,
I picked up a 6 volt sealed lead acid battery (6.5 volts fully charged) from
a local electrical dealer for about £8.00, Its a YUSA NP4-6, I think that I
could have managed OK with the next smallest size down, this can go in my
pocket or clip to belt, Yes I just use an old motorcycle battery charger,
and reduce the current. Its cheap rechargable, and I have had no problems
with it as yet.

Best Wishes
Peter Smith
