you are misunderstanding the old school ways of setting charge modes and profiles for lead acid batteries. the charge mode and float mode are legacy methods associated with iron core transformers and liner voltage regulators when you needed to physically switch between current levels and voltage levels.
modern chargers current charge up to a taper voltage level then switch to constance voltage mode which is typically 13.5-13.8v. anyway I am sure your understanding is lost in semantic nuances. it's not your fault but I want to help people in the thread understand how it works enough to have the right perceptions.
I won't get into the chemistry but when you put an SLA cell above about 14 ish volts you start to dissociate hydrogen in the electrolyte. That is gas. You may have noticed flooded batts are vented and SLA batteries have pressure release valves built in for this reason to prevent bad things

Don't tell me to stop. I'm just correcting you erroneous statements I'm not trying to pick on you. I think you are just extrapolating wrong statements from some simple misunderstandings of the electronics and battery systems
Trust an EE PhD as hard as that might be.
have a great day. and happy to direct you to good articles if interested.
The charger in a UPS is designed for SLA will cut off charging when the battery reaches 12.46v and shut off the UPS when the battery drops close to 11.59v. That means the LiFePO will never be full charged or discharged. So in that sense it's safe to use in a UPS.
However because it will keep the battery to SLA specs, you'll only be using approximately 23% of the battery's capacity. So that 10ah LiFePO will behave more like a 2.25ah SLA battery in the UPS.

I originally ordered one for a trolling motor battery but cancelled the order once I realized these two functions, especially Bluetooth monitoring because I want to know how much energy I have left so I don't leave myself stranded. Different people have different uses.

I bought my first lifepo4 less than a week ago, and like I said, I'd ordered this exact battery but cancelled after realizing it didn't have Bluetooth monitoring. Yes, I paid more to have that feature, because it was an important feature to ME. Others who have watched videos to learn about LifePO4 batteries might assume that this is a "standard" feature.
I don't expect a company to advertise "doesn't do x,y,z", but I just wanted to help others make informed choices. I should have added more context in my original reply, but was in a hurry, so I just pointed out that this battery doesn't have those features.
Those "are" both features, but if you know of somewhere to get those features anywhere near these prices, by all means share with the class, I'll buy several.
If you are comfortable buying LIFEPO4 from EBay, these are some exceptional prices.
