I recently got a giant pile of 4.3v Samsung cells (here), and don't have a charger capable of going over 4.2v. I know the capacity doesn't change a lot between 4.2 & 4.3v but I'd like to be able to use it anyway.
I have one of these CC/CV regulators and it claims to be able to do LiIon charging.
I've used it as a simple voltage/current regulator for fans and LEDs but not tried using it as a charger yet, because I'm not entirely clear on how to adjust it for charging a LiIon cell and would rather not try to figure it out through blind experimentation lest I guess wrong and have something explode.
Of the 3 pots one is voltage, one is current, and the other controls something to do with using it as a charger, though I'm not exactly sure what. I'm assuming it sets a cutoff point or something. Can anyone translate the description in the eBay listing into plain English and/or describe a test setup to check that it's doing everything correctly and safely while charging a cell?
