Versatile battery energiser

Olli 250B+ is a wonderfully versatile 12V battery energiser suitable for fencing all animals. Output energy 2J. A wall or post-mounted model characterised by low electricity consumption in relation to output energy. 20W solar panel available as an accessory.

Olli 250B+ features include an informative LED display, monitoring of fence condition, battery voltage indication, selectable battery deep discharge protection, and four power saving modes:

• full power
• half power
• day and night active modes controlled by light level

The versatile functions of 250B+ facilitate keeping the battery properly charged, thereby preventing potential damages caused by deep discharge. The charging control in solar panel operation also prevents overcharging the battery under any circumstances. These features prolong the service life of the battery. Fence voltage measurement reveals possible problems with the fence condition. The power supply can be cut with the power OFF button (removing the battery is not required for cutting the power).

Tip! We recommend using leisure batteries as the energiser’s power source instead of vehicle starter batteries. Read more about using different types of batteries with energisers >

Tip! Inadequate earthing is the most common cause of poor fence efficiency. By correct and adequate installation of earthing from the very beginning, you can avoid a lot of problems related to poor fence efficiency. Read more about functional implementation of earthing >
