Parking Battery-Power Station, 3X capacity and 3X cheaper than dedicated options + extra functionality

All power stations, all dedicated dashcam batteries, all battery management systems (BMS) I've used for my DIY batteries, etc., are unable to accurately reflect the state of charge (SoC).
This is due to the wide range in charge and discharge currents and the accumulation of measurement errors, which requires constant recalibration.
The most accurate is the Ecoflow River 3.
 
It’s been over 9.5 months since I installed Ecoflow River3 in my Jeep, powering two Viofo Mini2 dash cams via two USB-A ports using HK4 cables with removed voltage regulators (my original 5V direct connection system).
It worked flawlessly the entire time.
It survived both winter and summer, with sub-freezing charge protection tripping once and overheat charge protection tripping twice, while still powering the dash cams in both cases.

I love features like Wi-Fi and Bluetooth and app, the ability to remotely turn off the battery and the dash cam(s) when not needed, the ability to change the charging current on the fly via app, time-out, port memory, and the pretty accurate state of charge indication.
It is easy to install and maintain.
Overall, this is an excellent power station for a dash cam, much better than any dedicated battery on the market in my opinion.

Now the time has come, and today I replaced it with my DIY, LTO battery.

It's a simple drop-in replacement.
I didn't change anything in the car's wiring.
The LTO battery is powered via the same CLA-XT60-I cable, and the same two USB-A dash cam cables are connected via a Y-splitter to the USB-A (QC3.0) port on the LTO.

Looking nice. I'm waiting to see if maybe the new sodium-ion power stations or 12V batteries start showing up, but I'm not going for the outdated Bluetti. I can't quite decide which has served me better, the Solix C300 or the River 3, because both have advantages and disadvantages for my use case. Neither is perfect, but if you could combine them, I’d have the perfect one.
 
Yes, it's difficult to find the perfect option for every situation.
Solix has much better USB ports, but I prefer the River3 app and its functionality.
The new Bluetti Elite 30 V2 looks good - a sort of combination of Solix and River - but it has high self-consumption.
Standby DC power consumption is about 5W — about 3 times that of the River3.

It's interesting that you mentioned Sodium-Ion (Na+) batteries.
And the only Bluetti power station that uses these cells is, frankly, a joke.
Currently, Na+ cells are inferior to LFP cells in every way except the ability to charge at sub-zero temperatures.

I even considered building a battery using these cells:
3.1V 10Ah Sodium-Ion battery

They are drop-in replacements for the similarly sized LFP batteries I used here:
