We all know that Olympus created undue pain by chipping the E-M5 batteries (and overcharging for them). Now at last it seems that someone has reverse-engineered the chip software and created a fully-compatible BLN-1 battery that works with the Olympus original charger.
"A hundredth of a second here, a hundredth of a second there � even if you put them end to end, they still only add up to one, two, perhaps three seconds, snatched from eternity." ~ Robert Doisneau
Thank you for letting us know about the new batteries. As I have 4 from ExPro I'm not really in the market for batteries at the moment unless these turn out to have a proveable greater capacity - please keep us updated with how they perform. Do you know the voltage across the pins as it seems that Oly batteries deliver a slightly higher voltage than the third party batteries to date?

Re the voltage: the Oly genuine batteries state 7.6v, non-charger-compatible clones have typically been 7.4v (I already have two of these, plus the necessary second charger).
The pics on the Amazon site for these new Dot.Foto compatibles shows them rated at 7.4v. So I'd conclude that they are probably similar to earlier clones, with additional benefit of the Oly chipped software. That may mean they won't fully match the genuine battery's performance.
My main interest is to only have to take the Oly charger with me, as I know that it squeezes about 20% more charge into the genuine battery than the cheap clone charger. Hopefully it can do that for the Dot.Foto ones too...
