48 Volt Lithium Batteries

This does all the things that a 2-in 2-out interface should do; plus the big knob on top is winner, as are the input meters, 48-volt indicator and USB connection LEDs. All of that is on top, with no leaning and squinting required. Include a small form factor and sturdy build and it's a great value.

Very versatile, You can use lithium batteries to power it

Nothing beats these lithium batteries...they don’t die.

Great buy on quality 9 volt batteries. My smoke detectors use 9 volt batteries.

I already had two of the Nikon EN-EL15c Rechargeable Lithium-Ion Batteries, but I recently purchased the Nikon MB-N11 Power Battery Pack with Vertical Grip for my Z7ii which takes two of the EN-EL15c batteries, so having a spare made sense to me. I also own several EN-EL15 batteries for my D850 and have experience zero problems with Nikon batteries.

Works just great. When you order be sure and get 2 - 9 volt batteries ... B&H didn't tell me this and they sold me one ... which meant I had to run out and get another to make it work.

Like the ability to change 2 batteries at the same time and keep them together. Thinking about getting another for my other two Lithium Ion batteries.

I love the compact size of the charger, and it seemed to charge my lithium batteries quicker than my last charger.

These lithium batteries are very light and last a long time. Charger works well too.

Great for charging multiple batteries and the ability to charge from a 12 volt source is great for when you are traveling and need to top off your batteries.
