15.5J Electric Fence Charger, 600 Acres 30 Miles, AC 110-240V/DC 12V/Solar 3-in-1 Power, 12KV Output with LCD Display, Alarm & Remote Control – for Cattle, Horses & Large Livestock

15.5J Electric Fence Charger – Ultimate High-Power Protection for Large Farms & Ranches

When you need the absolute maximum output to contain large herds, deter aggressive predators, and manage fence lines with heavy vegetation, the LIFEALL YMD-Q780BJ 15.5J Electric Fence Charger delivers. With 15.5 Joules stored / 14.5 Joules output, this is one of the most powerful DC fence energizers available for farm use. Run it on AC mains, a 12V battery, or solar panel — your location, your choice.

What’s in the Box

• Alligator Clip Cable — Red for positive (+), black for negative/ground. Connects directly to any 12V battery.
• Alarm Horn — Emits a loud alert when an animal touches the fence. Mounts separately from the main unit.
• DC 12V 1.5A Power Adapter — Provides stable DC power supply for the alarm system when using AC mains.
• Remote Control — Wireless ON/OFF for the alarm system. No need to walk to the unit.
• Screws & Washers — Mounting hardware to secure the unit and prevent vibration loosening.

Smart Panel – Full Operational Visibility

• OUT-KV Display — Red LED shows real-time output voltage (typ. 12.3KV)
• IN-V Display — Battery bar graph + numeric input voltage reading
• POWER indicator — Green LED confirms unit is energized and running
• FAULT indicator — Short circuit or fence fault warning
• SHOCK indicator — Pulses green with every discharge cycle
• SENSITIVITY dial — Adjustable from low to high for different livestock types
• EARTH terminal — Grounding rod connection point (black)
• KV terminal — 12KV high-voltage fence wire connection (red)

Lower panel: Three interfaces — Power In (direct mode), Remote-control power input, and Alarm output port.

Installation Guide

Working Length: 30 Miles  |  Working Area: 600 Acres

1. Mount the unit — Secure to a post or wall in a sheltered, ventilated spot using included screws.
2. Drive grounding rods — Insert 1–3 steel rods 1.5m deep into moist ground. Poor grounding is the #1 cause of unit failure.
3. Connect EARTH terminal — Grounding rod → EARTH terminal via insulated wire.
4. Connect KV terminal — Fence metal wire → KV terminal via insulated lead.
5. Connect power — Plug in AC adapter (power in port), or clip battery cables (red=+, black=−), or connect solar panel.
6. Set up alarm — Connect alarm horn to the alarm interface. Pair remote control.
7. Power ON — POWER LED lights green; OUT-KV display shows live voltage immediately.

 Safety: Do NOT touch the energizer or fence wire while powered on. Keep children away from all fence lines.

Technical Specifications

3 Ways to Power Your Fence

Key Features

• 15.5 Joules Stored / 14.5 Joules Output — Highest-tier output for large livestock operations. Tested effective against cattle, horses, and large predators.
• 12KV Peak Output — Effective even through moderate vegetation. Real users report 12.3KV average on display.
• 30-Mile / 600-Acre Coverage — Powers extensive fence networks across large ranches and multi-paddock farms.
• Intelligent Discharge — SHOCK indicator confirms every pulse cycle; FAULT indicator instantly identifies shorts.
• Dual LED Display — OUT-KV and IN-V always visible at a glance, no guesswork about fence status.
• Wireless Alarm + Remote — Alarm horn alerts on breach; remote silences alarm from distance.
• Universal AC + DC + Solar — Three power inputs in one unit for any location.
• Adjustable Sensitivity — Dial controls shock threshold for different livestock species.

Who Should Buy This?

• Large cattle or horse ranches needing maximum joule output to command animal respect
• Farms facing serious predator threats — wolves, coyotes, bears, feral dogs
• Operations with heavy fence vegetation that drains low-joule units ineffectively
• Remote off-grid properties needing solar or battery-powered options
• Anyone upgrading from a standard plug-in energizer and needing proven high-power performance
