Mastervolt BI702-S BI Series Battery Isolator 70 Amp 2 Battery

The Mastervolt BI702-S BI Series Battery Isolator 70 Amp 2 Battery is designed for operators and vehicle platforms that require efficient dual-battery management in demanding environments. This isolator is suitable for use in patrol vehicles, tactical command posts, and off-grid expeditionary rigs, helping to prevent voltage drain across secondary battery banks while ensuring system availability.

Utilizing solenoid isolation logic, the BI702-S automatically engages and disengages between primary and auxiliary battery circuits based on voltage differential. This ensures that the main starting battery remains charged while the secondary bank powers auxiliary systems such as communications gear and tactical lighting. The isolator is designed to handle high-draw applications with a continuous rating of 70 amps, and it features protection against reverse polarity and transient spikes.

The BI702-S is ideal for professionals in law enforcement, military support, and first response roles who rely on redundant power architecture. Its silent operation and lack of moving parts make it suitable for covert operations where noise sensitivity is crucial. This isolator is compatible with standard 12V vehicle platforms, making it a versatile choice for various applications.
