The BreakerBatt is a polarity-agnostic battery eliminator with Lemo power loop-out. BreakerBatts are available in Sony L-Series, Canon LP-E6, and Sony FM-50 (for select Preston hand units).

Lemo In - Lemo Out

The BreakerBatt is the first Lemo-equipped, loop-through battery eliminator in existence. It lets you power devices that aren't equipped with a dedicated DC input, such as monitors and EVFs, with standard 2-pin Lemo cables and pass that power, unchanged, to other devices like wireless transmitters or receivers. 

Universal Wiring

Truly polarity-agnostic wiring means that you can plug in any 2-pin Lemo cable, and pass the same polarity power unchanged to the Lemo output. The rectified 7.5V output through the battery terminals means that no matter what polarity input cable you use, the battery output will have the correct polarity.

Minimalist Design

The hybrid injection molded and printed enclosure is very small (same size as standard battery), and lightweight (L-Series weighs 1.4 ounces; LP-E6 weighs 1 ounces). The BreakerBatt minimizes wear on the battery plate by allowing user to install and forget, plugging and unplugging only the Lemo cables.

Genuine Components

The BreakerBatt uses genuine Lemo parts. As always, our products are assembled in the USA.


  • Use any standard power source like a V-Mount or Gold Mount battery
  • Universal  power input – Use any 2-pin Lemo Cable

  • Regulated Battery Eliminator– 9-50V input; 7.5V output
  • Typical current output between 2.8A - 3.7A dependent on input source voltage
  • Protection Circuits – Overvoltage, undervoltage, reverse-voltage, over-current and short-circuit protection, over-temperature shut off, and soft-start
  • Unregulated Pass-through – Use any of our 2-pin Lemo Cables
  • Small and lightweight
  • Sony L-Series, Canon LP-E6, and Sony FM-50
  • Hybrid Injection molded ABS with printed Carbon Fiber-Nylon Composite enclosure

The Sony battery plate on the monitor is not great but this sorts it out perfectly. I’ve found canon dummy cables don’t last long either but again this works well and lasts.

BreakerBatt delivers!

Fantastic piece of kit. Wouldn’t use the Small HD monitor without it now.

This thing is the best. by far better than anything from small HD or any other after market companies.
