Question
I am looking to put a 32" TV into my motorhome, and therefore connect to the 12V supply. I am happy to use a voltage converter taking it from 12V to 19V, or whatver the appropriate voltage is, but less happy using an inverter, which seems a bit of a power drain. I know there are many 12V camping...

12v LiFePo4 battery and external power supply in parallel?
I have a project that will be powered by a 12v LiFePo4 battery (probably 6 or 12 Ah) with an "internal bms" (like this one).I would like the ability to connect the project to an external 12v (-ish) power supply when one is available, and have that external supply both charge the battery and power the project (which has a typical draw of < 1A, but may draw up to 10A).

Internal or external power supply for a monitor? Any difference?
The other one has a separate "power brick", so the power supply is solved externally. My question is, how much worse is the internal power supply solution, if at all? The monitors are: Samsung F24T350 vs. Samsung F24T370. As I saw, it would not differ in other specifications, but the one with internal power supply is cheaper by more than 25 euros.

There''s nothing to hear, at all.
External Power
M5Stack power circuit is designed in a way that you can use only a Li-Po battery (other than USB power) as external power source. For all other solutions you have to modify the PCB. If you look at the schematic you can see that the external 5V source could be added at several places, but in all cases you have to cut some PCB traces. The simplest
