1.5 Volt Solder Tab Battery

Yes you will get some bass roll off in the very very low end, so it will not go down to 5 hz like a set of 800.00 aphex 124a or 750.00 Arx distribution split. The 20 db of gain is a big plus, and of course having level control pots on all outputs, is an excellent feature. IF you are using to drive multiple low end subwoofers, you may wish to change the output capacitors. Existing ones are 10 uf 50 volt polar electrolytic, and you can easily change for 100 uf 50 volt polar electrolytic for a few dollars. Once you open the case these can easily be seen. The capacitors are easily available and are not expensive. If you try this you will need a solder sucker. Do not try soldering without one. Suck up all the old solder and remove the caps and replace all of then in the existing threw holes. They are marked for positive and negative on the pc board. Once you got them all in place just solder them back in. Once you do this for a few more dollars you can rival any expensive distribution amp. Would be nice if it was more than just 3 inch deep on the case. Most components are at least 6 inches.

worked just like the product I replaced except uses a double A battery instead of a nine volt.

What kept me from getting into FPV was the need to learn to solder, and repair your drone after a crash, and the ridiculously little amount of time you have from each battery. DJI solved that issue by making a robust drone that can take a pounding while giving you tons of safety features and long battery life, AND great picture quality. I've crashed this thing a bunch of times, even on pavement, and it's still held up. Highly recommend getting a battery holder since the battery can get ejected in the event of a crash. I use this thing professionally for indoor videos, and the clients have all be more than happy with the video quality.

I like these over others because you can re-use them easier. Solder points are more substantial than others.

I do not believe I have ever reviewed a flashlight before. This one is a neat convenient package. Interesting too that it has a 9 volt battery. Works well with a rotating switch. I like it give it a try

This little flashlight packs a punch. The secret is in the 3.7 volt/ 2.4Wh 16340 with built in USB micro rechargeable port (on the battery). That battery gives this little flashlight a powerful long lasting bright beam. I'm glad that I purchased two of them. I keep one in my toolbox and the other in my car. Highly recommended.

Maybe this isn't quite what Sony had in mind for it's adapter. I use a 12 volt dc sealed cell battery, plug a 120 volt converter into that, then convert it back into dc with the Sony adapter. I do that for extreme extended battery use for astrophotography field use. It seems to work fine. There's no overheating in any part of my contraption, including the Sony Adapter.

The battery charger that came with my Canon Rebel was 110-Volt only. On a Smoky Mountain vacation, my installed battery went dead and there was simply no place to charge it. This charger allows you to charge the battery by way of the cigarette lighter. No more will a dead battery stop me from my photography and I thank the B&H people for leading me to this alternative battery charger

I use this to recharge the batteries for my Nikon D500. I have only charged two at the same time once - when I first received with two new batteries that were down to about 15%. I like the fact that it shows the capacity of the battery, each individually. There is also a port for charging a USB device (5 volt - 2A output) I have not used and it also came with a short cord to connect to the 12 volt outlet in the car so batteries can be charged on the way to or between shoots which might be necessary when using Nikon's adapter for wireless flash as it does pull the Nikon D500 battery down rather quickly.

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.
