How does the module operate in cold weather conditions?

This guide offers essential tips for operating COBRA firing systems under cold weather conditions, with a focus on ensuring maximum safety and reliability.

Temperature Ranges and Firing Guidelines

0° to 32°F (-18° to 0°C)

  • E-matches/Talons/Clip-on Igniters: Limit to two in parallel or four in series.
  • Battery Type: Both LiPo and 9V batteries are applicable.

Below 0°F (-18°C)

  • E-matches/Talons/Clip-on Igniters: Limit to one per cue.

Battery Recommendations

9V Batteries

  • Preferred Brand: Energizer (Note: Duracell is acceptable but may perform less effectively in cold weather).

LiPo Batteries

  • Battery Check: For temperatures below freezing, ensure batteries display a "V-C" or "V-D" on the white label's bottom corner. If absent, contact COBRA Support for alternatives.

Best Practices

  1. Minimize Battery Exposure: To optimize performance, limit the time batteries spend in freezing conditions.
  2. Battery Warmth: Using hand warmers underneath the battery compartment can maintain battery temperature (optional but beneficial).
  3. Battery Installation: Install batteries just before the show to ensure optimal performance.


Q: What should I do if my batteries don't have a "V-C", "V-D",  or "V-E" label?
A: Please contact COBRA support for alternative solutions tailored to your specific needs.

Q: Can I use other brands of 9V batteries?
A: While other brands like Duracell can be used, Energizer is recommended for optimal performance in cold conditions.

Q: Does the V-C, V-D, or V-E apply to the COBRA 18R2 lipo, Audio Box Gen 2, or the Command Center?
A: No. All those devices and upgrade kits were designed with cold weather in mind and have been cold weather-rated since their introduction.
