 === limits of 15A shore power ===
-I would limit myself to 13A off a 15A shore power plug, or 1,560w. Assuming 10% conversion losses this would give us a **theoretical max of around 100A of converter charging** (14.4Vabs x 100A).  <-- shore power amps are at 120vac, converter ratings are at their nominal DC voltage (12vdc in this case).

-Lead chemistries require a minimum charge rate to stay healthy, and AGM more than the other lead variants.  In the absence of documentation from your battery mfg I would assume this is [0.2C](https://rvwiki.mousetrap.net/doku.php?id=electrical:12v:battery_capacity):
