The BreakerBatt is a battery eliminator with Lemo power loop-out. BreakerBatts are available in Sony L-Series (NP-F), Canon LP-E6, and Sony M-Series (FM-500H for select Preston hand units), and Canon BP-9 (for select EOS-C and Red Komodo) NEW!

Lemo In  Lemo Out

When first introduced, the BreakerBatt was 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. 

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 12V/24V 2-pin Lemo cable wired with Pin-1 GND polarity
  • Unregulated Power Pass-through  Lemo connectors pass power through to allow devices to be daisy-chained
  • Regulated Battery Eliminator  8.3-50V input; 7.5V output
  • High Output Power  5A typical constant output (2.6A for FM-50), depending on input voltage
  • Protection Circuits  Overvoltage, undervoltage, reverse-voltage (up to 40V), over-current and short-circuit protection, over-temperature shut off, and soft-start
  • Small and lightweight
  • Sony L-Series, Canon LP-E6, Sony FM-50, and Canon BP
  • Hybrid Injection molded ABS with printed Carbon Fiber-Nylon Composite enclosure
  • Designed and assembled in the USA

The BreakerBatt does not ship with a power input or output cable, but it is compatible with our 2-pin Lemo cables.

Please note that Version 3 BreakerBatts are not polarity agnostic. This feature was deprecated to allow higher output power. This device is protected against reverse-polarity, so your the BreakerBatt will not be damaged in the event the wrong polarity cable is plugged into the input. Lemo cables must be wired: Pin-1 GND, Pin-2 +VDC

*The Breakerbatt does not contain a battery*

All Rencher Industries products that use printed parts carry a 5-year warranty on the printed material. If your printed part warps, cracks, or fails for any reason, we will replace the defective printed part at no cost.

The BreakerBatt is a must for any monitor.

The BreakerBatt is a must for the SmallHD focus monitors or any monitors to be honest. This thing is built solid I also love the lemo out so i’m not limited to solely powering the monitor. I can’t say enough great things about the breaker batt. I understand why these things sell like hotcakes.

The Sony battery plate on the monitor is not great but this sorts it out perfectly. I’ve found canon ***** 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.
