SURE POWER 70Amp 1-Alt 2-Battery Isolator – 702D

Description

SURE POWER 70Amp 1-Alternator 2-Battery Isolator – 702D

The SURE POWER 702D Battery Isolator allows a single alternator to charge two separate battery banks while keeping them electrically isolated from one another. This prevents one battery from draining the other, ensuring reliable starting power and protected house or auxiliary loads.

• 70-amp continuous rating for dependable charging performance
• 1-alternator / 2-battery configuration
• Solid-state diode design with no moving parts
• Prevents battery cross-discharge
• Compact, durable construction for marine and automotive use

The 702D uses a solid-state diode system to automatically direct charging current where it is needed while maintaining electrical isolation between battery banks. This makes it ideal for boats, RVs, work vehicles, and off-grid systems that rely on separate start and auxiliary batteries.

Built for reliability in demanding environments, this isolator requires no manual switching and operates automatically whenever the alternator is producing power.
