MW & BFL13 - You two have probably learned, forgotten, learned again and forgot that you had once forgotten - more then I've been able to absorb over the last 15 years or so on batteries and charging in general. (Intended as a complement!).
Rolls, Trojan - have both been mentioned by you in the last few threads. The OP has Lifeline's (And as you both may recall as you both helped me with my bank - I have Lifeline X's 4 L16's too.
Lifeline seem to provide different guidance on a bank of their batteries can handle as far as higher Amps (Thanks BFL13!), then other AGM's. (I don't know the specific's on the differences between say what Rolls, Trojan, Crown, Etc. state for their AGM's, in comparison to Lifeline's.)
MW - You mentioned adding more battery AH capability, to live off of a higher SOC depletion point overnight. I basically did this, as we usually at about 75% SOC + or - 3 to 5% depending upon overnight heating and or running of fans for cooling. I did this, to try and reduce the volume of DOD Cycles usage.
After I walked my previous bank of the same batteries down. I did mention that a Lifeline Tech did spend a good deal of time trying to help me recover my existing bank. And one of the key things I took away from my conversations with him, and from the input provided to me by you two and others and other forums - was that adding higher AH's during Bulk/Absorb cycles help avoid sulfation build up on the mats.
So with Lifeline having a higher recommended AH's of goosing during those phases then other AGM manufactures - and I'm now doing that with my new bank, is not the higher 'juice' a better way of avoiding sulfate build up. (And as mentioned, I also do periodic Conditioning now too, also at the recommendation of the Tech. Under different time cycles based upon battery usage over the weeks prior.
As I read the info in the last few posts in this thread, I've inferred (Maybe incorrectly?) - that higher 'juice' levels are detrimental to AGM's? (Sure, they have a 'fixed' amount of material on the mats, but I'm not drying these out by ever getting near 'venting' escape levels...).
And OP. Not trying to hijack this thread. You have Lifeline's, smaller size bank and you do seem to push them to the 50% SOC level vs my 75% SOC levels - but specifically for Lifeline's, is why I'm asking the question to these gents to clarify if I've miss understood them:)!
Best to you all,
