SmallRig D-TAP Dummy Battery for Canon LP-E6NH - Continuous Power

In this review the SmallRig D-TAP Replacement Dummy Battery for Canon LP-E6NH is assessed for run-and-gun shooters and studio operators who need continuous power without swapping batteries. The bottom line: it solves the typical battery runtime problem by letting compatible Canon bodies run from a V-mount D-TAP supply, and it is fully decoded so it does not trigger the camera battery warning on supported models. It is best for long takes, timelapse, and tethered work where mains-style power from a V-mount pack is preferred.

Key Features

• Fully decoded for Canon LP-E6NH: Eliminates the low-battery or incompatible battery warning on supported Canon bodies so the camera behaves like it has an original LP-E6NH installed.
• Continuous D-TAP power: Lets the camera draw power directly from a D-TAP enabled external V-mount battery for extended recording sessions without changing the internal battery.
• Built-in safety protections: Includes overvoltage, overheat, and shortcircuit protection to reduce the risk of damage during extended use with external packs.
• Fire-retardant materials: Constructed from PVC and ABS fire-retardant plastics to improve reliability in demanding shoot environments.
• Works with common V-mount packs: Compatible with most V-mount batteries that offer a D-TAP output, and pairs well with SmallRig V-mount batteries that add additional protections.

Who It's For

This dummy battery is aimed at videographers, event shooters, and content creators who use Canon bodies that accept the LP-E6NH battery and need uninterrupted power for long recordings, timelapse, or multi-hour tethered sessions. It is especially useful when paired with a V-mount rig for a compact, portable power solution.

Those who should look elsewhere include users of Canon models not listed as compatible or anyone who prefers AC adapters designed specifically for studio mains power; also expect to test the dummy on your specific camera body since a few customers report mixed functionality on certain models.

Pros & Cons

Pros

• Provides reliable continuous power when paired with a proper D-TAP V-mount supply.
• Fully decoded for LP-E6NH so compatible cameras do not show a battery warning.
• Built with safety protections and fire-retardant materials for peace of mind during long shoots.

Cons

• Some users report mixed functionality and intermittent power loss on a minority of camera bodies, so compatibility should be verified before critical shoots.
• The dummy can show a low-battery reminder after roughly four hours and may need reconnecting to resume full function.

Specifications

Our Verdict

The SmallRig D-TAP dummy battery is a practical, cost-effective solution for shooters who need extended runtime from LP-E6NH-compatible Canon cameras. It is a good value when paired with a reliable V-mount D-TAP pack, offering decoded compatibility and multiple safety features, though buyers should verify compatibility with their exact camera body before relying on it for critical shoots.

Frequently Asked Questions

Will this dummy battery trigger the camera battery warning?
On supported LP-E6NH models the unit is fully decoded and should not trigger the warning; test it on your body to confirm.

How long will the dummy battery run without reconnecting?
Users report that the device will typically run and then indicate low battery after about four hours and can be restored by unplugging and restarting the connection.

Can I use any V-mount battery with this dummy?
It works with most V-mount packs that offer a D-TAP output, and pairing with SmallRig V-mount batteries adds extra over-current and over-voltage protections.
