Product Details

The Pro Mariner 11073 is a heavy-duty battery isolator designed to manage charging across multiple battery banks from a single alternator. This 70-amp rated isolator allows you to charge three separate battery banks simultaneously while preventing discharge between batteries when the engine is off, ensuring your starting battery remains charged.

Key Features:

  • 70-amp maximum capacity for demanding marine and RV electrical systems
  • Supports 1 alternator input with 3 independent battery outputs
  • Gold-plated terminals resist corrosion in harsh marine environments
  • Improved efficiency design maximizes charging performance
  • Diode-based isolation prevents battery drain and cross-discharge
  • Compatible with 12-volt DC systems
  • Solid-state construction with no moving parts for reliable operation

Ideal for boats, RVs, and other vehicles requiring separate house and starting battery banks. The isolator ensures each battery receives proper charging while maintaining complete electrical isolation when the alternator is not running.
