Getting started with V-Mount batteries is not a cheap investment. Even the cheapest V-Mount Battery + Charger Kit can easily run you well over $300+ Dollars. If you're looking to power up camera gear with a V-Mount battery, here's a closer look at a more affordable option using this adapter that can accept two common Sony L Series (NP-F) type batteries.

The V-mount adapter runs two 7.4V batteries in series to output between 13V-16V, and also has a d-tap connector if you plan to run a cable to power up optional accessories. The v-mount battery plate can be found via ebay (seen here).

In order to use these adapters properly and to get the best results, you should be using two exact batteries. Although you can find many aftermarket Sony L Series batteries for cheap, they will often come in different sizes, capacities, and ratings. I suggest buying them in pairs and labeling them together. Check out some of the Sony L Series Batteries via Amazon (found here).
