Why crews pick Block Battery for 24V and 28V rigs
One system, many voltages
Our battery systems support 14.4V, 24V, 28.8V and 30V, so one inventory feeds mixed camera and lighting packages.
Every mount pattern
V-Mount (V-Lock), Gold Mount three-stud and 28V B-Mount plate options cover legacy and current cinema cameras.
Built for set abuse
Robust electrical and mechanical design stands up to truck handling, weather, helicopter rigs and run-and-gun work.
Travel-ready options
The Protean splits into two isolated 75Wh packs, and the SLi-D600 and SLi-D1000 disassemble for air travel.
Service, re-cell and trade-in
LOGOS-150 G uses a re-cell and service capable housing, and trade-in options are available on several models.
American made, veteran owned
Designed, manufactured and serviced in the USA by a family-owned, veteran-owned company started in 2007.
How we cover 24V and 26V V-Mount power
Many cinema cameras run above the usual 14.4V V-Mount range. ARRI Alexa SXT, Alexa Mini and Amira packages use 24V, while Alexa Mini LF, Alexa 35 and Sony Venice 2 use 28V B-Mount. Block Battery systems support 14.4V, 24V, 28.8V and 30V so you can feed those rigs plus monitors, gimbals and lights from one battery inventory.
The Protean ships in four mount configurations, including a 28G Gold Mount Plus version for 26V on-camera and a 14V V-Lock version. Tell us the cameras and accessories you run and we will confirm the right mount and voltage combination.

An industry standard in the US cinema market
“Everyone knows that the most important link in a camera system is the battery. That's why we rely on Block Battery, we love the service and support they provide.”
“I like the batteries because they allow me to run the gimbal, camera, and multiple monitors at the same time. I bring them out onto locations with the helicopter … and they are light enough that the pilots don't complain too much.”
“After more than three years of using and owning Block Batteries, I can say that they give me a sense of security, each and every production day. I'm glad I took a chance on Block Battery.”

Frequently asked questions
Do you make a true 26V V-Mount battery?
Our systems support 14.4V, 24V, 28.8V and 30V. The Protean comes in a 28G Gold Mount Plus configuration for 26V on-camera, plus 14G Gold Mount, 28B B-Mount style and 14V V-Lock versions. Send us your camera list and we will confirm the right configuration.
What do these batteries cost?
Most systems are custom quoted through authorized dealers. Some are listed: the Protean at $275, LOGOS 150 G at $429, SLi-300 at $600 with charger, SLi-D600 at $2,150 with charger, SLi-D1000 at $2,725 with charger and Artisan Block at $2,850 with charger.
Can I buy direct from Block Battery?
We sell through a national dealer network rather than direct retail. Send the form and we will match your build to an authorized dealer who handles the order.
Can these batteries fly with me?
The Protean can be configured as two mechanically and electrically isolated 75Whr batteries for carry-on and shipping rules. The SLi-D600 and SLi-D1000 disassemble for air travel. DOT, IATA and IMO lithium transport rules still apply.
Will one battery run my camera and my lights?
Yes, that is what the multi-voltage design is for. The SLi-600, SLi-D600, SLi-D1000, Linkey Block and INDY 3000 / 5000 / 6000 handle sustained draw from ARRI SkyPanel, Vortex, Aputure, Astera and HMI fixtures alongside camera power.
Do you handle fleet orders for rental houses?
Yes. Fleet quantity pricing is available through authorized dealers, and one multi-voltage inventory with V-Mount, Gold Mount and 28V B-Mount plates can cover every camera package in the house.
