Great battery

By Jeffrey
Rated 5 out of 5
Date: 2026-10-20

I was looking for a new battery to power my Sony HVR-Z5U, since the very old ones are starting to lose charge. This is a perfect replacement. Long hours of shooting, no worries about sudden discharge of power.

Worthy investment.

Previously purchased no-name no-f batteries on Amazon for use in sound devices 633 mixer, I would highly recommend these (more expensive but higher quality) np-fs. For reference I had issues with the contact sleeves on my old np-fs being pulled out of the battery by my device’s pins. I have not had that issue with these, and have experienced much better run time and more consistent charging. I’ve also enjoyed running these through a splitter plate to power a bs1h camera with paralynx arrow+ video tx and a portkeys pt5-ii monitor at a weight point much lighter than mini v-mounts or gold mounts for less robust camera support systems.
