This energizer features deep discharge protection for the battery and incorporates an energy-saving system that adjusts power consumption based on fence condition. It includes LED indicators for both fence and battery status, facilitating prompt detection and correction of any issues. Designed for versatility, the "Helos 4" is effective for containing animals like chickens, cows, and horses, while also deterring wildlife such as deer and stags.

The MB300 operates on 230V mains or a 12V battery, excels in ease of transport, and can electrify up to 25 km of fencing, with an added security feature for theft prevention.

The "Helos 4" provides more power flexibility (battery, mains, solar), covers up to 24 km, and includes energy-saving technology and detailed status indicators. The choice between them depends on the user's priorities: the MB300 for simplicity and portability, and the "Helos 4" for sustainability and advanced monitoring.
