Converter starts/runs for a few seconds then stops

So am I to conclude that one must go all in. If I want to go lithium then get lithium converter. If not then normal basic converter?

No. Any charger or converter that does 14.4-14.6 will do and you can put a timer on the 120v side if you will be away and set it to float when you get back.

Guys use their charge wizard with the PD converter which makes it do 14.4v for four hours then it drops to 13.6. Same drill as for Wet Batts.

The PowerMax LK model converters can be set to 14.x and there it stays till you change it, so that would need a timer if you will be away when and after the LFP BMS finishes its balance routine. You then set it to 13.6 or just not do a float. It also has a regular three stage automatic, but the time at 14.6 is 1/2 hour, so not enough time for getting a bank to full before it drops to Float.

Best thing would be a portable battery charger with amp choices and batt type choices. If the LFP is under 41F, you must charge it at fewer amps, but your converter is only one amps "size". Portable chargers can be set to 10/20/40 amps and you can pick AGM for 14.4v instead of Wet at 14.8 volts so you can use the Gel for the LFP.

It is bogus to say you need a special charger for LFP. Seems to be a thing that LFP salesmen say to extract more money from you than they got already for the LFPs! :(
