7.2 Lithium Battery

Sometimes I even forget the I have to charge this battery. It's an Info-Lithium Battery with 6600mAh at 7.2V and it have a very long life!

Purchased the DMW-BLC12 Rechargeable Lithium-ion Battery (7.2V, 1200mAh) as a backup for my Leica Q. Works flawlessly and entirely likely that the two are identical except for the branding printed on item (the two companies have a close relationship with one another). Lasts equally as long as its Leica-branded counterpart, fits perfectly in the Leica charging unit and seems to have no downsides. And for the price compared to Leica's own model, it's a no-brainer.

This lithium battery is very reliable.

This manual flash has everything I need and especially like the lithium battery. just bought a second unit.

Long lasting Lithium battery makes it cost effective.

Lithium without the need to recharge. Excellent long-life battery.

I bought one, have to buy another, great sony lithium battery.

One of the Q&A’s says the Bescor BLS50AC dummy battery adapter kit is not compatible with the Olympus E-PL9.  I asked Bescor ( answers@bescor.com ) why the kit is compatible with the Olympus OM-D E-M5/M10, but not the Olympus Pen E PL9, since all three use the same Olympus BLS-50 battery.   The response was: “It will work. Your camera just needs to be added to our list.” The Bescor is 8V 3A. The Olympus battery is 7.2V 1175 mAh (1.175A).  I did some online research to see if a device built for 7.2V could operate at 8V.  One person describing himself as an engineer posted that 7.4V Lithium batteries actually span a 6V to 8.4v voltage range depending on state of charge of the battery.  Another “senior electrical engineer” said that because all devices are designed with some voltage tolerance value, a 7.4 volt device means 7.4 volt +/- 1 to 1.5 volts.  Still other posts indicated that you can use a 3A power adapter on a 1.5A device.  By logical extension, I figured (I don’t actually know) that since the PL9 uses a 7.2 volt battery, it is probably designed to also work at 8 volts, and is also okay running at 3A. Based on the response from Bescor and the Internet voltage and amperage responses, I decided to purchase the Bescor and use it with my PL9.  I haven’t seen any sign of overheating or other problems with this setup so far, but will update this review if that changes. I did not deduct points for the need to leave the battery compartment open because I knew that would be the case when I bought it.

Battery i ordered fit perfectly and it works better when its 7.2v not 7.4 volts. Same as factory battery.

I bought this battery for my Canon EOS R when I saw it listed for uses with the BMPCC 4K camera because they use the same battery. Sure enough it works perfectly. Some people asked me about the 8.4 volts it puts out since the canon battery says 7.2v. A fully charged Canon battery maintains a charge between 8.4v and 9v respectively. 7.2v is a low battery, so don’t worry about that. Down side is you will have to invest in some D tap cables if you want to run a monitor ext. however the best features of the PowerBase is the power remaining button and the fact that you can you it without the need of a v mount plate which is still an option if you need it. It mounts directly to a tripod. Worth the money!
