I'm looking to purchase a charging/protection/boost circuit for some lithium batteries like the USB-C option seen here, but it has a low-power cutoff that will be annoying. I'm going to be using it to power an LED headlamp, but said headlamp already has some electronics in it so it won't be powered directly, and it will be frequently off for a few minutes at a time, then on again. I've looked at a lot of these types of circuits, I can't seem to find any that have all the features I want and are sans the low power cutoff (so if anyone knows of a nearly identical circuit sans cutoff, that would be great). How would I disable/bypass the cutoff? I'm guessing there's a cap and a resistor for feedback, and maybe I could increase the cap size and resistor size, to give myself more like an hour before cutoff? Or is that little tiny 8-pin chip reprogrammable, so I could just disable that "feature?" The easiest thing of course would be to just add a 100ohm resistor across the output but then if I forgot to turn that off it would discharge itself in about 4 days max which I don't want. So any ideas are welcome!
Also if this is the wrong forum I apologize, and please move it appropriately. Thanks!
