Heads up readers, during the NAB2016 Show next week keep an eye out on these particular IndiPRO Tools power cables for an additional discount. These cables offer a custom Mini-Tap to Dummy battery that can keep your Canon or Sony cameras powered up from a V-mount or Gold Mount battery. The cable is regulated inline to ensure your camera is operating at the correct voltage (as v-mounts are typically 14V+ out).

The difference between these cables as opposed to a standard D-Tap is the custom Mini-Tap which splits into two additional power option. (Other cables pretty much hog the entire D-Tap port). Once connected to your v-mount battery, you will still have an option for an unregulated D-Tap out to power up an additional accessory + a USB 5V out. That's three possible accessories you can power from a single battery without an expensive distribution system.

Some might see this as overkill, others may see it as an incredibly versatile solution. Especially for those opting to move into the new Sony Camera systems (A7sII / A7RII) that have poor battery life, you'll definitely be looking into some type of external power solution.

The Switronix PB-70 is a unique battery system as it can work as a normal V-Mount battery to power up your LED Lights, but can also double as an external battery solution for many camera systems (including BlackMagic, Canon, etc). Sure you can use other V-Mount batteries to power your camera, but the mounting solution incorporated into this particular V-Mount from Switronix is what makes it clean, simple, and minimal.

A small quick release adapter first mounts under your camera (or cage) similar to a battery grip. This allows the Switronix PB-70 battery to attach under the camera. And under the PB-70 battery itself is another tripod mount, so you can attach another Tripod QR plate directly to the PB-70 battery. It works very similar to standard camera body battery grip.

Of course the Switronix Powerbase does not really have to mount under a camera body, as it only needs a 1/4-20 threaded mount. This can be mounted to the top of a Blackmagic 4K camera, or on a cheese plate off a shoulder rig. By incorporating these creative mounting options into a V-Mount battery is what makes the PB-70 a versatile battery system.

There are smaller, lighter, and cheaper power solutions for the Sony A7 cameras, but the capacity of the Switronix PB-70 means you can run all day (if not several days). And when mounted to your camera, it still has Two P-Tap out for you to power two other accessories at the same time (on camera LED light, external monitor, etc). And when not used with your camera, your investment means you can still use the PB-70 to power your Large 1x1 Studio LED Light Panels - incredibly versatile.

Optimizing the Sony A7s camera for best performance means working with an external battery because the stock internal batteries suck. Getting the best means adding a 4K HDMI recorder like the Atomos Shogun, because it can't record it's highest quality internally.

To run a camera system with these add-ons, you'll need a cage system for mounting these accessories. While there are many options for putting a kit together, in this video we'll be taking a look at the Varavon Sony A7s Armor II Cage, Varavon T-Power A7s Battery Kit, and Varavon Armor Shogun Cage.
