Thunderbird B50 12V Battery Fence Energiser

The Thunderbird B50 is an Australian-made electric fence energiser designed to power up to 5km of clean fencing under ideal conditions. Its 12V battery operation makes it a practical choice for paddocks, lifestyle properties and remote locations where mains electricity is unavailable.

With 0.52 joules of stored energy, the B50 provides reliable performance for small livestock fencing systems. It can be mounted to a post or hung directly from suitable electric fence wire or tape, allowing it to be used for permanent and temporary applications.

Flexible Off-Grid Fence Power

The B50 provides dependable electric fence power where a standard wall outlet is unavailable. It runs from an external 12V battery and can be paired with a compatible solar panel to help maintain the battery in suitable off-grid installations.

An optional AC mains adaptor provides another useful power choice when the energiser is installed near a suitable power supply.

Suitable for Permanent and Temporary Fencing

The compact design allows the energiser to be mounted securely to a fence post or suspended from suitable live fence wire or tape. This flexibility makes it useful for smaller permanent paddocks, rotational grazing and temporary livestock-control systems.

Actual fence performance will depend on vegetation load, fence construction, insulation and the quality of the earthing system. Heavy grass contact or poor earthing can considerably reduce the effective fence distance.

Is the Thunderbird B50 Right for Your Fence?

The B50 is well suited to small paddocks, temporary grazing areas and off-grid livestock fencing. For longer fences, heavy vegetation or more demanding multiwire systems, consider selecting an energiser with greater stored energy rather than relying only on the advertised kilometre rating.

Correct earthing is essential. Contact Horsley Wholesale if you need help choosing an energiser, solar panel or earth system for your fence design.
