New 2 stage PD lithium Converter charger yet?

Note that I am not advocating for leaving the LFP connected while on shore power with an active converter.

I am commenting on how the converter makers see the problem, where they assume the converter will be on during shore power time ( nearly all the time for most RVers AFAIK), and they have to be sure a connected LFP won't be ruined during that time. (They do not imagine the RVer disconnecting the LFP)

So their various attempts to make the converter "compatible".

Guys on Tech Issues are not like most RVers? which means they are more likely to be willing to do a few things instead of being totally automatic and hands free?

Just saying that so far IMO it seems the converter makers have not solved their problem of making their converters totally "compatible" with LFP (something of a moving goal post itself for what is needed?)

I did say their converters are not totally compatible with FLA and AGM either, but the penalty in dollars for the RVer who treats them as such is low compared with the penalty cost of doing that with LFPs.

The OP is trying to get as close as he can to hands free by maybe swapping out his converter, but it seems like he is as good as it gets now with his OEM converter, unless he wants to do more manually himself.

Excellent questions!

My take: The vast majority of converter/charger sales are to regular folks who generally have a set-it/forget-it mentality. There are always going to be folks who will leave their converter on 24/7/365 while connected to a lifepo4---for better or worse.

Back in the day, it took manufacturers some time before they offered 3-stage units for lead-cell batteries to address long-term float needs. I believe manufacturers are going through the same learning process with lifepo4. Many of the lifepo4 converter/chargers currently on the market are single-stage 14.6v units---a less than ideal charge profile. Manufacturers are now transitioning to 2-stage units to address the potential overcharging risk posed by single-stage units.

Lastly, lifepo4 cell/battery manufacturers ship their units with a 30-50% SOC for a reason. It's the ideal SOC for a lifepo4---for the short and long-term. I think it's just a matter of time before manufacturers eventually transition to 3-stage units to address this unique lifepo4 storage/float requirement. Until then, those set-it & forget-it folks (who may be striving for maximum lifepo4 cycle life) will just have to remember to turn-off their 1 and 2-stage lifepo4 converter/chargers when they're not camping.
