The Cyclops 2.5 Joule Stallion DC Energizer is a battery-powered electric fence energizer designed for smaller farms, rotational grazing systems, and remote fence applications where AC power is unavailable. Operating on 12V DC power, this low impedance energizer delivers reliable livestock control while maintaining fence voltage under moderate vegetation loads. Built for portability and durability, the Stallion DC is ideal for temporary fencing and off-grid applications.
Power Ratings
Stored Energy: 3.2 Joules
Output Energy: 2.5 Joules
Key Features
12V Battery Powered: Designed for battery operation in remote locations and portable fencing systems.
Low Impedance Technology: Maintains controlling voltage even under heavier vegetation conditions.
Heavy-Duty Surge Protection: Built-in lightning resistance and surge suppression help protect internal components.
Portable Fence Capability: Ideal for rotational grazing, temporary fencing, and remote pasture systems.
Made in USA: Built for agricultural use with durable construction.
1 Year Warranty: Extended warranty options available.
Grounding Recommendation (Important)
We recommend 3 feet of grounding per 1 joule of OUTPUT energy for maximum fence performance.
For this energizer:
2.5 Output Joules = Minimum 7.5 feet of grounding recommended
We recommend using one 6–8 foot ground rod minimum for proper operation.
Proper grounding improves:
Fence shock performance
Voltage consistency
Vegetation handling
Overall energizer efficiency
Energizer Sizing Recommendation
We recommend sizing your energizer using the Joule Per Mile Rule
When selecting an energizer, consider:
Total fence length
Number of fence wires
Vegetation load
Livestock type
Future expansion plans
Choosing an energizer based on output joules rather than advertised mileage ratings typically provides more reliable fence performance.
Common Applications
Rotational Grazing: Portable paddocks and temporary fencing systems
Remote Pastures: Ideal where utility power is unavailable
Livestock Containment: Suitable for cattle, horses, sheep, goats, pigs, and other livestock
Farm & Ranch Use: Temporary and permanent battery-powered fence systems
Reliable, portable, and built for demanding field conditions, the Cyclops 2.5 Joule Stallion DC delivers dependable electric fence performance wherever power access is limited.
