2 3A Size Rechargeable Battery

[Lithium] I have just a couple of rarely used pieces of equipment with this size battery. The rechargeable feature keeps me from having to stock up on the regular kind of battery.

[0.185 lb] Great light but getting the rechargeable battery will make you use it so much more often.

[Yes] I love the fact that the battery is rechargeable!

[0.495 lb] 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.

[1.2 V] Best rechargeable battery for flash light.

[LED] Typical for Pelican this light is extremely well made and Bright. I already own several other rechargeable units so I switched to a Rechargeable Pelican Battery as soon as I opened it (Through the two included Duracell 123 in my bag).

[1x White LED] Wonderfully bright, compact and rechargeable without removing battery

[9.9 x 4 x 1.6"] Nice bright little light the rechargeable battery is great

[0.05 lb] the battery works and is rechargeable. i would make a v2 of it usb type c
