$155

This item is really open box, but I didn’t save the box. I bought it a few months ago, only to discover in a quick test that it is a mismatch for the LED light I had intended to power with it. I have just bought the larger SmallRig battery and therefore am selling this one. Condition is perfect.

$25 less than the sale price I paid.

I use one of these batteries on a small rig. I like the small size, light weight, clear large digital screen, and the multitude of powered ports. The only thing I don't like that goes to your point, it's not packed with batteries on the inside feels like half empty. As a result it's capacity is low. It will only power my camera and a small field monitor that probably draw like 15w for around 3hrs. I can only imagine powering a light would be futile.
