  1. Hello,
    it would be nice if you could do a few more cycle tests of li-ion batteries to address some questions that repeatedly pop up on the internet but that are rarely if ever satisfactorily addressed.
    Namely: how many full-discharge-cycle equivalents do you get if you cycle a li-ion battery at 50-0%, 75-25% and 100-50%? In other words, is fully charging (up to 4.20 V) worse for the battery than fully discarging it?
