Battery-powered fence energizer 122B

rechargeablesmart

Product description The Olli 122B is a movable energiser for medium-length electric fences, designed for 12V battery operation with mains connection capability (adapter included). It supports simultaneous connection of a mains adapter, a 12V rechargeable battery and four 1.5V D (LR20) alkaline backup batteries. The unit’s smart energy management automatically selects the best power source and ensures continuous operation: when the rechargeable battery charges the alkaline set maintains output; when rechargeable battery is depleted the unit switches to alkaline; if alkaline are depleted operation continues from the 12V battery at reduced power and lower pulse frequency.
