Just about to start putting this in finally!
I've bought the turbo timer & 18v interface board.. and intend to use it with 2 12vdc batteries.
I asked before and you said this should be fine.. but reading your FAQ page - viewtopic.php?f=21&t=21181
Noticed you have said.. on the 18v interface faq
Q: Can I use this on 24V or higher?
A: No. Don't try it. This is strictly for a 12+6, 18V system.
Will it work with 2 12vdc batteries ? Does the FAQ need updating ?
One other question.. I have the 2 relays for the 18V interface board.
Do I require another relay for the battery saver relay circuit ?
