The 12V Hotline HLB525 (was P525) Buzzard energiser is a high power fencer for all uses, including 3 reel and netting electric fences.

The Buzzard electric fence energiser is recommended for use on long boundary fencing applications where it is not possible to use a mains electricity fencer. As long distances of electric fencing are frequently used with the Buzzard energiser, it is likely that earth stakes will be required for effective operation.


The Hotline HLB525 Buzzard electric fence energiser is a very powerful fencer with two output levels. If animals are being fenced for the first time, the energiser should be set to 'high' for the first week and can then be switched to 'low' after this initial period in order to conserve the battery life. If however, the electric fence is being used to keep animals out, the energiser should always be switched to the 'high' output position.

As the Hotline Buzzard energiser is designed to be used on long lengths of electric fencing, a powerful rechargeable battery of around 75-125Ah will be required. The LED will flash GREEN when the unit is working correctly, but will change to RED when the batter requires re-charging. A buzzer will sound if the battery terminals are connected incorrectly.

Please refer to the section 'Installation of Battery Energisers' in our Guide to understanding modern electric fences for more information on connecting your energiser.

Main Features:

  • High power 12Volt Battery unit.
  • Ultra Bright LED indicator.
  • The LED will flash GREEN when the unit is working correctly, but will change to RED when the battery needs charging.
  • A buzzer will sound if the battery is connected incorrectly.
  • Two output levels
  • Fence & Ground connectors complete with crocodile clips.
  • Ideal for up to 25km of fencing.

Hotline battery powered electric fence energisers are supplied with all cables necessary for a standard installation.
