Cutoff Voltage
hi, my charger has a cutoff voltage of 4.08V at 18650 Sony VTC4´s LiMn and at Samsung Li-Ion, too. This might not be correct. I also own the old version of this charger (Intellicharger I2) and that one has a cutoff voltage of correct 4,20V. For me this means that I can´t make a use of the full capacity of my cells. Hope to get answer from fasttech staff soon.

to prevent misunderstanding: The Display of the NITECORE D2 Charger is displaying 4,20V. But checked with multimeter and also with my Gi2 Box says round about 4.1 Volts/4.08Volts by multimeter...

I have a D2 and a D4 from FastTech and cutoff measured with a Fluke 80 is 4,20 Volt.
I suggest an high precision measuring setup:

Ah you're an expert? Guy, it doesn't matter which kind of multimeter I'm using... my measurements were facts. Tested also with different multimeter. But thanks for your useless comment.

And by the way... got an RMA for the charger and fasttech accepted return of it. Don't think because your correct cutoff voltage that all items are fine. We call this a defect. That's it. 😁[b][/b]

Gotcha....gotcha....RMA: "REFURBISHED MULTIMETER ANOMALY"...

So I'm lucky, I got insulted only because I'm objecting mine are perfect and a bad measurement could occur......

Cool man,...keep cool !
