I've been using this battery from K&F for a couple months and I've been really happy with the experience. The battery has really solid construction as well as a bright and reasonably large display. On the back you have the classic V-mount with charging pins that are typical for V-mounts. Truth be told, I think I charged it with these once and used USB-C the rest of the time. There is also a very small light, more on this later.

One side has a power button that if you tap once, you get a quick display of charge status. Pressing and holding will get you a more informative display for charging status that includes the ports and their output. as well as a very useful. When in this configuration, the little light will turn on and give you just enough light to do simple tasks in the dark.

On the other side is a D-tap port with a rubber cover and on the top are the remaining ports are along the top of the battery.

The battery really does deliver as a smaller sized, on the go option to keep your lower power gear running. Great for auxiliary lights and other random pieces of kit you run day to day. I was even able to power a motorized slider with the DC port. All in all, I'm really pleased with the battery and hope it can be cycled and last a long time. Well done!
