Dave, it's a 12 volt battery. Lead/Acid (sealed). Just like a car battery. Down the bottom it lists the regulated 12V as over 2 amps so given the right plug end it should be fine. Two pounds though. And unregulated (as is). Didn't read the whole schpeel. OUT OF STOCK...
New things on the PD horizon. Stay tuned. Heat Exchanger (very slight materials modification soon, still 100% stainless steel) and Exotic Vapor Tubes (a bit further off, but we are using the prototypes and they are pretty cool)
Busy week this week, so if you e-mail Pammy, expect delays. I am going in for cataract surgery. The surgeon says,"wicked cataracts for a man your age...". You may (or not) have seen how blind I am in that assembly vid.
Yep, the PD has been built by a blind guy (well beyond legally blind).
I gave up driving over 3 years ago. I can still see some out of the right eye, but the left has been gone for ages. Mostly I work by feel or from about three inches away (using the right eye). You should have seen me pounding nails when I built the shop.
Friday morning, with luck, that will be over (for the left eye anyway, then start saving for the right eye).
