Rugged, portable energiser for livestock, horses, and game fencing

Compact yet powerful, the Gallagher B100 offers flexibility and reliability for a wide range of fencing needs. It can be run on a 12V battery or two 9V batteries, giving you extended operating time and options to suit your setup.

The energiser includes smart indicator lights that clearly show fence voltage and battery status at a glance. Its adjustable settings let you choose full or half power, as well as different pulse frequencies (fast for training, slow for conserving energy). Special day/night modes automatically adjust the output depending on animal activity, helping you optimise performance and battery life.

Expandable with a solar panel for sustainable charging, and with theft-prevention options built in, the B100 is built to perform wherever you need reliable fencing power.
