It all started with a guy that showed up on BLF offering cool charger https://budgetlightforum.com/t/-/24744 but he(his boss :) ) is very complicated in doing some serious business.
But I got same thing for much less money than he offered, and I am very happy with this unit although It has some minor disadvantages... But not that bad considering that with mentioned disadvantages it could actually prolong battery life?
I have two ‘good’ chargers. The iCharger 106B+ and the Pila IBC. In my experience from both of them, the terminal voltage of 4.20V (or the the failure of the charger to charge to 4.20V) is actually dependent on the cell. I have tried charging various brand-new Panasonic, AW, Sony, LG, Samsung and Sanyo cells and while the the iCharger terminate at exactly 4.20V, the holding voltage of the specific cell determines whether that cell holds 4.20V when taken off the charger. Seldom do I see a cell hold a 4.20V, or least for a few minutes actually. (side note: almost all Pila IBC does not terminate at 4.20V, always on the low 4.14 to 4.19V)
Pila are considered as premium chargers so I am glad to hear that they also have low termination...
I think this lii-260 charger is real champion, real progression in charger world. Hope plenty of charger manufacturers will follow this idea "all in one charger".
But there is always place for improvement...
Thing that could make Lii-260 charger as a perfect choice would be added option for changing termination voltage from 4,35 & 4,2V. I think they can do that if they want... So dear China engineers if you will ever watch this thread made one and you'll be the king, and of course don't let your fellow citizens copy your patent ;)
Update: I tested one more brand new blue ultrafire 2600 mah :) battery for friend and got following results:
675 mah capacity(add +10% and results are 742mah), but incredible well internal resistance of 54mR(this is very strange because last one mR measured on crappy fires were 150, maybe 16340 is fitted inside this tested 18650 battery?),
I do not have any D capable charges in queue for review (One of the Soshine does C cell, it is not perfect, but useable).
The only working D cell charger I remember to have tested is the BT-C2000.
If I wanted to buy a D cell charger that could charge many cells, I would look for a Maha C808M, but it is a bit on the expensive side (I have never tested it, but my general experience from using Maha is good).
It would be very nice if it could charge all possible batteries + 4,35 to 4,2 V selection and of course for less than 20$ if possible :)
Me also... I am waiting for pro review of this little charger. But even now I trust him and for first time I am leaving charger unattended :) and it is doing everything what I need...
I just say "liito kala charge!" And he charges, and then I say "liito kala measure capacity!" And he does all that while I am gone on beer ;)
