I am new at this and was hoping for some guidance.
I currently have this setup for testing-
2s 18650 7.4V --> Constant Current Boost Regulator (XY-SJVA-4) --> 20W LED
I can't seem to find clear information regarding adding the ability to recharge via USBC as I have two 18650 running in series.
Is something like the attached photo suitable? It seems to vary from the tp4056 as it doesn't have load terminals.
Can I do this?
Any advice would be much appreciated.
