I've been using Pure Sine Wave APC UPSes (1000VA) for a long time to keep the basic things running like Modem, Router, Networking, Office, etc so that I can work from home and not worry about electricity going causing an issue. I've orderd a 50AH 24v (25.6V) LiFePO4 battery with then intention of swapping my two AGM 12V batteries for just one 24V LiFePO4 battery, but I know that floating the lithium battery under the max voltage isnt going to be all good for it in the long run, so I had an interesting idea.
Why not use a Portable Power Station, like the Bluetti EB3A to act as the UPS for when power goes out? So to extend the battery runtime, I can easily plug in my 24V LiFePO4 battery to its DC Input port and that can act as 'solar' or 'car' power to extend the runtime of the 268Wh by another 1,000Wh so that my office can stay without mains power for a long long time (usually about 150w max, 100w average).
To keep the battery charged up, I can use a Lithium charger externally always plugged in the wall or even a small solar panel with a basic mppt charge controller.
The total cost of this is comparable with a 1000VA Pure Sine Wave UPS, but with now, a battery that will last 10 years.
What am I missing or is my assumption that this will work fine is purely off?
