The Secur 25 is a compact and robust energiser, primarily designed to run off a 9 Volt disposable battery. A 9 Volt battery can be mounted inside the internal battery compartment, making this a very portable unit ideal for strip grazing and short to medium electric fences. This unit also features a variable power output which allows the unit to be adjusted for young sensitive animals or to preserve battery, and a Eco 1/5 power mode. Comes with an earth stake and all connection leads. Battery is not included. This energiser can also be used with a 12v rechargeable battery or mains power if required. The adapter to use the 12v battery is included, but it is worth noting that a standard leisure battery cannot be internally housed. If you wish to internally house a 12v battery then the Fit One Charge One Kit is recommended. If using a rechargeable 12v battery then a 2 watt solar panel can be mounted to increase battery life. To use mains power an adapter is required to be purchased separately.
