Intelligent battery combiner offering trend-based switching, auto voltage detection and near-zero voltage loss for reliable marine and mobile battery systems. Also serves as a voltage sensitive relay (VSR) / smart battery isolator for efficient alternator charging and emergency start support.

• 400 A continuous rating
• Auto-detects 12/24 V systems
• Virtually no voltage loss compared with diode isolators
• Trend-based switching with four selectable timing profiles
• Bidirectional voltage sensing and dual power supply
• Will not close if one battery is
• Manual emergency parallel via push-button or switch (30 s)
• Prioritises the starter battery for alternator charging

Suitable as a direct replacement for diode isolators on boats, motorhomes and off-grid systems to ensure efficient charging and dependable emergency start support.
