24v Panel 12v MPPT to charge 12v 4S LFP Battery

You can use a 600 volt panel to charge a 12 volt panel with a MPPT controller made for that voltage. That is why MPPT controllers are made.

Would it be good practice to use a 24v panel connected to 12v MPPT Charge Controller to charge LFP?

Higher panel voltage would have less loss or allow higher awg feed line.

Portable use would allow controller to be located closer to battery for shorter 12v run.

Panel could produce usable power in less ideal conditions.
