Per BFL, “This all only applies to being on shore power using the converter. On generator you don't leave it running long enough to matter. On solar it might matter depending how early in the day you get to Full.”

Fair enough,
I’d only point out (unless I’m misunderstanding…) that this charging scenario seems to assume a practice of keeping a charged battery on an active converter-charger - but other than for ‘occasional’ cell-balancing (an activity requiring 100% SOC…) why do so with a LFP??
I would counter that this apparent consternation (possibly a FWC thingy?) mainly applies to ‘unattended set and forget’ shore power charging (as is typical with lead batts)…But even if using a ‘less that ideal’ charging device for LFP, one need ask how realistic of a scenario is this??
And, to arrive at the dreaded ‘the slide-out won’t work’ gottcha, it suggest that once ‘shore power’ charging has been completed (to whatever level?), for protection, an LFP battery needs to be sequestered….Why is this??
I’d counter that one can merely shutoff the onboard converter-charger (at it’s breaker…), at which time 12v power will come from the now charged, still active battery (minor loads only, and possibly with some solar assist?), while leaving shore power connected for 120v heavy appliances (e.g. air cond, etc)…
Regardless of the charging source (and, charged to whatever desired SOC?? - definitely NOT a lead acid thingy!!), one can simply opt to discontinue charging and just live for a considerable time off the battery’s deep reserves…This is exactly what I do, and with 400a/hr LFP and 660w of solar, seldom the need for shore or genny power - the last time I ran the genny was about 11 mos ago (and have since circumvented America…), and if in a park, ONLY use shore power where shading prevents harvest or when using air conditioner…In most other scenarios, the pass-thru inverter (concurrent with harvest) does the job…Just Saying :)
