Ahhhhh...
Ah cheap as in "Honey, forget Taco Bell's 99 cent special. Tonight we dine at Costco's food court".
AMAZON?
Was mulling something around 10 lbs 5 Kg that could be controlled drained to 0% and used with a BiPAP away from home in an outage. A nifty critter with remote 10 watt LED lamp and USB charger for an eBook.

"In my mind, the ideal Lifepo4 charger would offer adjustable charge voltage (Like the PowerMax - but with a higher limit), and be a two stage design (though float is not necessary, nor harmful) so that the battery does not sit for an extended period while being held at maximum voltage..."
What limit is desired? It goes to 16.5v now.
It is adjustable single voltage (which does two battery "stages", bulk and absorption), but you want a charger end's two-stage.
Not sure how you can have a two-stage (at the charger) adjustable voltage that is automatic as seems to be desired here. You would need an adjustable timer to go with that, but that would need a trigger since you want the battery to get fully charged first and you don't know how long that will take.
The trigger would have to "see" that the battery is full somehow, and voltage can't be the trigger of course. However, it may be ok with Li batts, which start their absorption stages at a high SOC and you don't want them to be all the way full?

I just put 3 Battleborn 100 Ahr batteries in place of 400 Ahr of AGM.
I have 1050 watts of solar and after much consultation with BB my
converter is fine as is my solar controller, which is programable.
I was impressed with their construction and assembly methods.
I thought about making my own pack, but, could not find an external BMS I would trust. ๐
Our experience boondocking with the BB Lithium is fantastic. The voltage stays very constant througout discharge and they provide up to 300 A if needed. Highest I have seen (microwave) is 140 amps to the inverter.
They seem like a solid company and all is assembled in the USA. :B

Hi,
I would buy this--except for the cold weather issues:
