My AGM to Lithium conversion
Here is a quick article I wrote on my adventure going from AGM batteries to Lithium. http://rvbprecision.com/rv-projects/rv-lead-acid-agm-to-lithium.html http://rvbprecision.com/rv-projects/rv-l...

More ‘real world’ (to bring from the theoretical, OR to bypass more ‘lead acid-centric’ misnomers…lol!)…
Yesterday, on the Oregon Coast (mid-state, cloud free), the 660w of rooftop solar was harvesting mid-day just over 30amps….So with the higher recovery rate of LFP, and per our typical usage pattern and with heater running at night, this 1 hr of passive charging at 30a generally meets or exceeds our daily power consumption…But we don’t always experience a cloud free day on the OR coast, right??
Here’s a cut & past email I sent to a pal a few days ago upon our arrival:
(Note, that this is shortly after adding another 220w of roof-top solar to the existing 440w, and SOC’s relating to the 400a/h LFP…)
….Left CG this morning about 10 miles south of Grants Pass enroute to coast, about a 2.5 hr drive…Rain and intermittent drizzle with occasional clearing to Low cloud cover, occasional openings of blue sky as we neared coast, typical day in Oregon, not the best time for harvesting…Was between 60-61% SOC upon departure, and upon arrival, but nevertheless, upon our arrival was at a whopping 75%SOC!!…This represents nearly 30a/hrs in just 2 1/2 hrs - 660w is a lot, but Judging by the WX, I would not have thought this result even possible - needless to say, I’m very pleased with this discovery!!
