A load test on the LA batteries will tell the tale, but if you are saying that your consumption is 48 Ah per HOUR, then I doubt LFP is your answer. Yes, you could certainly put enough on to handle...

That's amazing Rodd, and thank you for the report. One question - I'm following your 30 minute absorb after the acceptance rate drops below 5% (most cycles), but I am following Lithionics...

No problem, but kind of pointless. AGMs or FLA will accept higher input very briefly before the charge acceptance rate drops below the 60 amp output of the Sentry, at which point it doesn't how many...

Never quite understood the attraction of dc to dc chargers. Their low amperage output doesn't take advantage of a decent LFP's charge acceptance rate. The same function is accomplished with two...

There's some evidence that LFP will develop memory and lose capacity if rarely fully charged, but my impression is that if fully charged and absorbed for 30 minutes that can be rectified. Other than...

There is no particular reason why LiFePO4 batteries cannot be used as a starter battery. What does the starter care where the required amps and voltage comes from?
