I too was speaking about amp hours as measured by a shunt battery monitor. I suspect Creativepart was also.

That's a good testimonial, and thanks for the information. How well do you like your JC Refrigeration 12 VDC refrigerator? Are you glad you had it converted?

I did some research on the SiO2 batteries, looks like they have a small following, do you have them? I am still reading about some charging hoops that have to be followed. What has your experience been?

Looking at some specs for the SiO2 battery they seem to be the same weight as lead acid batteries. So if weight is a consideration for 400AH or 600AH battery bank lithium would have an advantage.
