If you're looking to power up a small camera or accessory for an extended period of time, Sony L-Series batteries are a popular choice. It's a very common battery used to power anything from small LED lighting, monitors, wireless video transmitters, etc.
The IndiPro Tools Battery Mount comes ready with a 1/4" thread and 15mm clamp mount which makes it easier and cleaner when mounting to any rig. The build quality exceeds that of the cheaper plastic battery trays as well. IndiPro Tools has a rubberized coating, lower profile, metal backing plate, and the batteries lock in rock solid with no play.
Aputure has some of the most popular LED Panels available for the budget shooter, and now they've added a nice high power single point source LED Light called the LightStorm COB120. If you've worked with Fresnels, the new COB120 can be used in similar ways. Still photographers who are now working with continuous lighting will also be familiar with it's MonoLight type form factor. With a Bowens Mount adapter, you'll also be able to use many available Light Modifiers such as a Beauty Dish, Softboxes, Snoots, etc.
As camera systems get smaller one design issue could be the smaller batteries that leave us with short run times. This is especially true with many of Sony's mirrorless camera systems. If you're looking for longer run times, IndiPro Tools has a number of different Battery and Power solutions available as seen in this interview during the NAB 2016 show.
One important design difference with the IndiPro Tools cables they point out is having DC converters placed outside of the dummy battery. Not only does this reduce any possible heat from generating inside the camera (problem for some Sony cameras), but they also say it prevents any digital noise (a.k.a RF, EMI, etc.) that could affect your recorded footage.
Just a few days after I decide to pick up the redesigned shoulder pad, they show off their V Mount power solution. If you're not familiar, these types of adapters are virtual power stations for your entire rig. Using high powered V Mount batteries (like Sony or Anton Bauer), you can power up all the mounted accessories from LCD Monitors, LED lights, Portable audio recorders, and even down to juicing up your camera. The V Mount battery can be quickly swapped out with another to keep you running all day instead of having to deal with multiple battery types and chargers. This setup can also act as a counterweight on rigs, so instead of having useless dead weight, you've got a functional piece of gear.
This V Mount power station has a built in HDMI splitter so that you can run two monitors, (2) 12V outputs, (1) 7.2V output for your Canon Camera, (1) 5V out, and even has (1) 5V USB port out to charge your cellphone. The kit comes with (1) V Mount battery, (1) V Mount battery plate (which also acts as the charging station for the V Mount battery), and the redesigned Shoulder Pad (the one I just bought). If you've shopped for DSLR Rig V Mounts + Battery Packs, this kit is very interesting. Additional close up images and information following the jump (click here).
