Electric Fence Energiser – 20KM Range

This fence energiser delivers a peak voltage of 10,000 volts and 2.0 joules of pulse energy, making it ideal for livestock containment and paddock maintenance. It can be mounted directly on the included earth stakes or fixed to a wall, making strip grazing and portable setups easier than ever.

Dual Power Options:

• 240V mains power (adapter included)

• 12V battery operation (battery not included) — perfect for off-grid setups

Battery Usage & Recommendations

If using a 12V battery, we strongly recommend a deep-cycle battery (also called a 'leisure' or 'deep-draw-down' battery). These are designed to be discharged and recharged regularly without damaging battery life.

A car battery (initial surge battery) may also work, but should not be allowed to run too low, or it may degrade over time.

Note: Most batteries will stop powering your energiser before they're fully flat — typically around 10.5V.

Runtime Estimates:
This energiser has an average current draw of 100mA.

• A 12Ah battery will provide approximately 120 hours of operation

• A 6Ah battery will provide approximately 60 hours of operation

Actual runtime will vary depending on fence condition, load, and vegetation.

Solar Charging Recommendation:

To keep your fence running at maximum voltage and pulse energy, we recommend connecting your battery to a solar panel (sold separately). This helps maintain full charge and ensures consistent performance.

When to Recharge:

Electric fence equalisers are essentially transformers. They take your 12V battery input and step it up to high-voltage pulses.

• If your battery loses 20% of its charge, your fence will lose about 20% of its shock power.

• Most energisers stop working once the battery voltage drops below ~9 volts.

• To maintain fence strength, recharge before your battery drops below 10.5V.
