Re: AGM charge acceptance

Thanks so much for clarifying

Just talking about longevity, not reducing charge time, so assume on shore power.

Say a not-high-end but true deep-cycle AGM is drawing down to 80% but never...

Re: AGM charge acceptance

I won't try of course to speak for MS, but "100%" for purpose of the "increasing Amps input shortens engine runtime" discussion is along the lines of AH replaced, compared to total AH required, as...

Re: AGM charge acceptance

That .4C will very quickly no longer apply during absorption, lead scales back demand for amps pretty rapidly once CV hits.

But yes, in your case, multiple large banks, will factor into the...

Re: AGM charge acceptance

Wut?

Try 6-10 hours, maybe more!

And yes huge difference in lifetime between even 98% and 100%.

Also between once a week vs every cycle.

If you can't do that IMO save your money, 6v GC2...

Re: AGM charge acceptance

This shows the huge LFP advantage, much higher CAR, some you can fully charge < one hour!

Plus no need to fill up in the first place, in fact keeping at or even trying to get to spec'd 100% will...

Re: AGM charge acceptance

Yes, this only saves time during the relatively short Bulk constant current stage.

Look for a maximum charge rate specification from the maker.

.2C means for a 300AH bank, no point buying a...
