Funny you should post this, I just received one from DD4 yesterday and tried it out with some brand new LG HE2’s, they have like 3 cycles through them. Anyway the new one stops at precisely 4.18v.
The older one always stops at 4.20 unless you have a weird battery like one of my Xtar 16340, that one will not go above 4.16 on any charger.
Having read Nitecore’s propaganda on the newer model it is supposed to be tweaked for newer IMR batteries, so maybe that is part of the new firmware?
Where did your’s come from?
I’ll try some other batteries on it to see if other batteries behave the same in this charger.
I did also charge 2 Ni-Mh AA batteries and it did not seem to get them as hot as the older model, so that part is all good. They terminated at 1.48, same as the old one.
I am happy with it as is, (great build quality and nice packaging), bought as a backup/additional unit to get batteries the same voltage for SRK’s etc., just weird how they change in newer versions.
Well, I have recently purchased one as well, Nitecore i4 (2014 version). I’m not really thrilled with it. Some cells are too much over, others under. Perhaps it is user error, or cheap DMM. If my apartment doesn’t catch fire, I’ll keep using it
