V Mount batteries are big, heavy and pack the power required for energy-hungry broadcast cameras and lighting.
Due to their intended use, V Mount is expensive, often eye-watering so. A standard Rotolight 95Wh can set you back a cool £300, so any savings, however, small are always welcome.
However, as I have found to my cost in the past, cheap batteries are not always what they’re cracked up to. Stated capacities are often well below advertised, and as a general rule of thumb, if the deal seems too good to be true, then it usually is.
What’s more, if you think about it why would you risk sticking a cheap battery on to your kit, if anything is going to destroy your camera it’s an unrated, unreliable source of power.
Berenstargh is a German company that has just started distribution in the UK. While the price of their V Mount batteries is still high, you are saving a little when compared to the likes of Rotolight.
When the Berenstargh units arrived, I gave them a full charge, and on the first run, the charge and power compared like-for-like with my usual V Mounts powering the Rotolight AEOS.
But would the power be consistent? I tested the V Mount batteries over a couple of months and in that time discovered a few interesting additional features that helped save the day more than once.
