I have used a "Ex-Pro® Olympus BLN-1, BLN1 [CHIPPED EXACT] High Power Plus+" battery for over a year in my EM5, works exactly as the Olympus one, the capacity is similar too.Anyone use the aftermarket Olympus BLN-1 Batteries for OMD-EM5? How is your experience with them? I am looking for aftermarket batteries that can be recharged in the Olympus charger.
I'm interested to know, voltage does the progo charge up to in the olympus charger? I have the "upstart" brand, that only charge to ~8.0V (as opposed to ~8.6V with the olympus batteries).I have Progo batteries that charge in the Olympus charger. Whatever they did on these batteries to get them to work in the Olympus charger was somewhat flawed. They do not get fully charged, shutting off a few tents of a volt early, according to my voltmeter, I have to put them in a generic charger to get them to their full charge. Looking at amazon reviews for Progo, I see someone else has reported the same issue recently, so it seems nothing has changed. I have two, and the pair is still working after a year though.
I don't believe any of the third party BLN-1 batteries will charge fully in the Olympus charger - they lack the necessary circuitry that the Olympus-branded BLN-1s have. Certainly my Wasabi-branded batteries don't. I decided to just use the generics since the generic charger itself is smaller (and takes DC in, so it can be powered from the car). Battery life seems to be just as good as my OEM battery.Anyone use the aftermarket Olympus BLN-1 Batteries for OMD-EM5? How is your experience with them?

Progos shut off around 8 volts, same as your "upstarts". Both are 8.4 volt batteries, while a real BLN1 is 8.6 volts.I'm interested to know, voltage does the progo charge up to in the olympus charger?

7.6 and 7.4 volts are the nominal voltages when the battery is under load and working in your camera. That is how they are labelled. When you measure them fresh out of the charger with nothing connected, that's the open circuit voltage, which should be 8.6 and 8.4 volts in this case.Some confusion above. I have a real BLN1 in my hand and it is 7.6V not 8.6V.
I have two EZO Power BLN1 equivalents. They are 7.4V They charge OK in the Olympus charger.
They seem to hold about half the charge for a quarter the cost. I now have two genuine ones and two EZO ones.
My two Ex-Pro Chipped Exact from 2013 are still working fine with Olympus charger and my new E-M5 mk2. And my estimate of around 70-90 percent of OEM capacity is still holding. They have been well worth their price. I just ordered Hähnel HL-ON1 because the E-M5 mk2 eats up batteries even faster than the mk1.Two "Ex-Pro chipped exact" here too and they work and charge just like the original battery. It might be that they give only 70-90 percent of the originals capacity but they are still well worth their price. I've had zero issues using them for a year now.
