This ECO-WORTHY 12V 100Ah LiFePO4 battery stands out as a lightweight, low-cost upgrade for RV, trailer, solar, and backup power setups. The Bluetooth app works well, the battery has handled mini PCs, camping loads, trolling motors, and solar charging, and it is much easier to carry than lead acid. The main catches are price swings at checkout, no handles on this case, and the need to match your charger or power station voltage carefully. It looks best suited to 12 volt systems that can charge lithium properly.
The battery can be charged faster by wiring a higher-voltage battery into a power station solar input instead of using a limited 12V input.
The battery is much lighter than a similar sized lead-acid battery, which helps with installation and handling.
The battery can run a mini PC with Home Assistant OS 24/7 from a 100W solar panel without reported problems.
The battery supports high continuous current, which can fit applications like trolling motors with typical draw under its rating.
The final checkout price can differ from the advertised amount due to coupon application and taxes.
Using the battery in a UPS or inverter-style setup for long continuous runtime can be unsafe because the UPS charging and output circuits may be designed for smaller batteries.
The battery may not be compatible with every power station or charger setup because some units require higher solar input voltage than 12V.
Eco-Worthy warranty handling can become costly for series or parallel battery banks when a matching replacement is refused.

I bought a pair of Eco-Worthy batteries less than a year ago to run in series. One recently suffered a confirmed manufacturing defect. Eco-Worthy acknowledged the defect and confirmed it was well within the warranty window, but refused to send a free, matching replacement.
As we all know, putting a mismatched battery into a series bank compromises the whole system. Eco-Worthy explicitly admitted this in writing, stating that a matched production batch is a necessity for consistent performance.
Instead of honoring the warranty by providing an exact match or refurbished unit at no cost, they weaponized this technical necessity into a sales pitch. They offered a "goodwill BOGO deal" on their latest, more expensive model: they would give me a matched pair, but only if I paid out of pocket for one of them.
To get a "free" warranty replacement for a defective product under a year old, I was forced to buy a second battery I didn't need, at a higher price than my original purchase. They essentially held my broken system hostage until I agreed to buy more product.
I bought it under protest just to get my rig back online, but consider this a heads-up. If you run a multi-battery bank, Eco-Worthy's warranty policy is designed to extract more cash from you when their product fails.
Your biggest issue is how old and capable is your current systems battery charger that likely is charging your marine cycle batteries. To charge these, you will need to confirm your "RV Load Center" is capable of charging lithium batteries. If it is old, it probably can not, and you will need to upgrade it/replace it. But if the trailer is newer, there is a chance it is compatible. You will get 2-3x the power out of these batteries vs your standard lead acid marine battery. Add a couple of 100W panels and a small solar charge controller, and you will never need to plug in again or run a generator. I have this battery, I also have LiTime, I like the ecoworthy.

A 100ah 24v with a 100amp bms has plenty of charge/discharge current to supply the typical 1200w available from a 1500va UPS. Capacity of the battery doesn't matter, the UPS is looking at voltage. It will factor in a 7ah default to determine runtime, but that can be ignored. Battery degradation is too common in SLA, so the UPS isn't going to shut down based on a timer.
The UPS won't charge to the 100% for LiFePO4 (SLA on a UPS will get up to approx 25.5v to 26v - 100% on Li would be 27v resting 28.4v full), so some routine maintenance of cycling the battery will be required for battery longevity.
I have seen builds with people gutting and rewiring old UPSs, plus adding new charger controllers to build power stations, so it can be done properly, as long as you gauge your wiring correctly and you know the limitations of the equipment.
