I've looked at these 13 v devices and always wonder it they will handle the 15 CDC of an auto charging system like all our radios. Some 12 vdc evils will only work properly if the have 12 vdc not 13.8 vdc for example. The information on these devices is lacking. Any insight into to this issue? Just too bad the rest of the electronics world does not have a ham background. Sigh! Thanks, Bob k6ecm 73 Sent from my iPhone

Ramesh,
If it were me, I would use a 7ah 12v backup battery with a "normal" 12v float charger, then use a buck converter to lower the voltage down to 5v. Something like this would do nicely: http://www.ebay.com/itm/262908222815
Using 12v storage makes things more "standard".
Just my 2c.

I'd like to use a battery bank on my remote node down in FL (renowned for electrical storms!), so keeping the Pi up during brown-outs and loss of commercial power is a big plus. In case folks are interested - here is a link to a good article providing a review of various products: http://www.theoutpost.org/6-techy/raspberry-pi-usb-power-bank-ups-pass-throu... Unfortunately, the leading contender, the product from RS Electronics (brings back memories of my "jollies" as an Apprentice heading up to Alum Rock in Birmingham ;) is not available in N. America. There must be other equivalents out there..... Anyone have a lead on such a product? Thanks!
