PS love the snorkel, and how is that extra battery going?
looks like Mitch answered your query whilst I was trying to type one handed with my thumb on the world's smallest keyboard while driving.
Thanks, the Snorkel's at the powdercoated but I should have it back before Sunday's run. havent gotten around to wiring up the 2nd battery yet (too many things in the fire) but I did buy an A/B/A+B battery switch for it and a cool battery power indicator:

But the things's bigger than I thought it would be - trying to figure out a good place to install it.
