The Gemini range of electric fence energisers will run from either a 12v battery or from a 110/240v mains power supply, perfect for those wanting to make the transition from a temporary, portable fence to a low maintenance mains system without the expense of purchasing two energisers. This is ideal if you want to future proof the fence and envisage shifting from temporary to a more permanent installation and for those needing to move small poultry systems around their land where power requirements change. The units come with earth, fence and battery leads and a 12v mains adaptor; it can be mounted on either a wall or wooden post or hangs neatly on the Hotline ES2 earth stake.
