I'm just wondering if anyone knows if it would be possible to modify an existing 4.20v Li-Ion charger to terminate at 4.30v or 4.35v? It would be nice if an existing (inexpensive) Li-Ion charger could be opened up and a trim pot adjusted to adjust the termination voltage. Any chance of doing this?
I've seen Comfy's post on the CC/CV board. I guess the worst case scenerio could be be to tear out the inards of a cheap charger and place that board inside (though I'd like to see that board have a cut-off and stop charging and figure out what that 3rd pot does).
