I was trying to access the 12 volt article to reread. I was on this page "Step 3: Smart Ways to Increase Your Battery Storage Capacity" and Safari said it can't open the file (tried it twice). I also tried the link to the 12v plug in monitor on same page and it took me to scamp owner's page.
The links for the 330Ah battery and the fancy 12v monitoring system both work.
Thanks for all your work on this page!
