Per calculator.net, voltage drop at 12v 166a for 4/0 over 10' is ~1.5% (View Post)

FWIW, the Bluesea version is apparently AYBC kosher for main DC fusing on boats, presumably the Samlex version is as well. (View Post)

I check SG just after absorb (soon after transition to float). The last bit of absorb can make the batteries spit a bit, so I wait until that's done to read. Absorb mixes the acid up some, so the… (View Post)

5 years isn't a terrible lifespan for a typical AGM battery. All batteries eventually die of old age, even with little or no use. Also, going from 13v to 12.4 quickly isn't as bad as going from… (View Post)

Gassing point = transition from bulk to absorb. Bulk = constant current, absorb = constant voltage (~7.2v) (View Post)
