The orion TR is just a DC-DC converter.
It's not a full charger (for LFP)! It can be used as a charger due to its CC limiting capabilities, but it does lack actual charging profiles!
So when set to eg 14.2V, it will provide 14.2V, any time. So eventually it will overcharge a LFP inless you manually shut it off once the battery is full.
LFP should never be left at high voltages for long periods. Once full, charge should stop or go to (low enough) float.
For lead-acid? No problem. It just fixes the smart-alternator issues if you have them. Lead acid doesn't mind (actually likes) to be as high SOC as possible continously.
The Orion TR Smart has bluetooth, but not only that: It's a fully functional charger. you can set the appropiate charging curves as you would for LFP.
So unless you're using it as an occasional charger, which you disconnect once the battery is full, I won't recommend the non-smart (unless you have lead-acid)
