any merit in running dual battery packs ?

[Dean Pappas]

Hey Bob,
It's a matter of solderability, Bob. Either you screw an aluminum heatsink to the tab with the hole, or you solder a fin directly to the tab. Some of the surface mount regulators take a solder-on heatsink because they don't even have a screw hole.

Dean,
 
If adding a heat sink, I would think aluminum would be better. In my experience it always dissipates heat better than copper or steel. Don't know about tin or brass, but aluminum should be lighter anyway.

Hello Urs,
The Jaccio regulator is a great item, but I am concerned about running with more than 3 volts of headroom: this increases the power dissipation.
It may simply require a heat sink be added to the regulator component. That is usually just a tin or brass fin soldered to the big tab on the IC.
Jim? Whadda you think?
