Budget Move Set

I have prepared a few months ago a Patona battery for my E-PM2 and am very happy with it, now an e-M10 is gotten that uses the same battery, and this property, which is the charger "next to nothing" the 2 batteries are to be looked at but tempting.

My trust in Chinese cheap products in conjunction with Li-Ion batteries is somewhat limited, so When unpacking and find that the charger 2 served by the 4 pins of the 2-cell batteries, wondering whether I right now the thing back chic or simply throw away and only the battery used. Always with Tranquillity. First measure.

The battery has 4 pins. -, +, T and S. What is S, I have not figured out, maybe a shield (Shield). + And - is clear, T is a temperature sensor, NTC 10KOhm against -. So no balancer port, then a Balancer is probably the battery itself built with. We hope that now just that this is also the case with the Patonas.

While the Olympus-original batteries (BLS-5) a decrease in the resistance between - can be detected and T when heated, the Patona remains solid at 10KOhm here. Okay, so no temperature sensor. Can you do so. But one could also install a that would pennies extra charge for the extra security now not invested so completely wrong.

On the charger. The original Olympus is specified with charging voltage 8.35V, teaches 10KOhm temperature sensor as well as 8.4V, the charge voltage decreases with decreasing resistance as we have then probably safety. The Patona Charger is indicated as 8.4V, but delivers 8.45V charge voltage, even when direct connection of a resistance to the third pin of the base (the shell has only + and -) will change it nothing.
In both cases, I can not rule the way measurement tolerances, might both stick to their own information, we are talking about, after all, a measurement error of less than 1%, this accuracy achieved hobby / consumer equipment only with luck. Anyway, basically in the green zone.

The Patona batteries are indicated with 7.4V instead of the 7.2V of the original, so watch the "in principle" together. The consumer, ie the camera, this 0.2V difference are certainly matter, but when charging Li-Ion batteries, a little caution is called for, so I would recommend using the Patona charger exclusively Patona batteries and not the original battery to load. Since the charger does not care about the temperature and the battery also does not answer, that fits so together. Unattended shop should perhaps be rather avoided.

And since herumblinkt end of the charge the Patona-Ladeegrät quite confused between red and green, the trust is still a smidgen lower, will thus be used only on the road, where the many supply options are clearly a big advantage. In your car charge the batteries, just fine. Via USB is also useful when one has of this cell phone battery packs, then you can also recharge his camera battery. Why is a USB-A port on the device has not yet been opened up to me, but Chinese engineering is not always comprehensible. Perhaps intended also to fit devices that make the fatal mistake and provide as device current to the connector. Something like the Chinese built, too.

In short: Patona batteries are a decent alternative to the original, half price at about the same performance, this charger is fine as road-Notladegerät definitely, for everyday operation I would both for the original and for the Patona batteries prefer continue to use the Olympus-loader.

For's price / performance ratio full 5 stars.
