Thunderbird BD22 Strip Grazer Battery Energiser

The Thunderbird BD22 is a compact, Australian-made electric fence energiser designed for strip grazing, temporary fencing and other short portable fence runs. It can power up to 2km of clean fence under ideal conditions.

Designed to hang directly from the live fence wire, the BD22 is easy to move between paddocks as grazing areas change. It is a practical choice for farmers who need a lightweight energiser without access to mains power.

Why Choose the Thunderbird BD22?

• Powers up to 2km of clean fence under ideal conditions
• Suitable for strip grazing and temporary electric fencing
• Operates from four D-cell batteries or an external 12V battery
• Hangs conveniently from the live fence wire
• Pulse light confirms energiser operation
• Low-battery indicator helps identify when batteries require attention
• Coated electronics provide protection against moisture and insects
• Australian made

Designed for Portable Electric Fencing

The lightweight hanging design makes the Thunderbird BD22 particularly useful for rotational grazing and temporary paddock divisions. It can be repositioned as required without installing a permanent energiser at every fence line.

Performance depends on fence construction, vegetation load, earthing and insulation. Keeping the fence clear of grass and ensuring the unit is properly earthed will help provide reliable operation.

Battery and Solar Options

The BD22 can operate from four D-cell batteries or an external 12V battery, providing flexibility for different farm applications. Thunderbird also lists a compatible 5-watt solar option for suitable installations.
