If whatever you own cannot stay at 14.4 volts until the batteries charge to 1/2% then this alternative may prove to be useful.
https://www.mouser.com/ProductDetail/MEAN-WELL/RSP-1000-15?qs=l0g2inPJSHPM9nYLAnDFNw%3D%3DWhen converter charge rate drops to <50 amps, throw switch and have this unit come online. This unit charges perfectly safe at 70 amperes but if course is limited by your setting the adjustment screw from outside the case to 14.40 volts.
Would work with ANY 12 volt bank including lithium, AGM, calcium and flooded simply by tweaking the voltage. People who complain about the price have not spent a thousand dollars on batteries. Driving a Ford Pinto and kibitzing about the new Rolls Royce extended chassis :)
L16 Lifelines just bout HAVE TO LIVE 10+ years perhaps 15, when treated right and boondock camping is not done for many months at a stretch.
And then the complainers will try and justify three sets of two-thousand dollar Lifeline L16's makes more sense than the price of one Meanwell.
The RSP Meanwell is not a chew & spit item. When finished RV'ing hand it down or sell it. Makes a super battery charger.
