Battery Isolator Mastervolt BI 703 83007030

The Mastervolt BI 703 is ideal for systems that include two or more batteries, which operate independently, providing power to consumers at 12 or 24 V. These batteries require independent charging with reliable battery isolators or battery combiners.

• Battery isolators that divide the charging current with minimal energy loss.
• Charge Mate for connecting and/or disconnecting two batteries.
• Battery Watch for monitoring the status of your batteries (can also be used as a main switch).

The Mastervolt BI battery isolators are based on classic diode technology. The diode voltage drop (approximately 0.6 V) can be compensated by adjusting the output voltage of the connected charger or alternator. The Mastervolt Mass battery chargers and the Alpha Pro charge controllers feature automatic voltage drop compensation.

The Mastervolt BI battery isolators are compact and fully solid-state, preventing wear. Their weight ranges from 580 to 1300 grams. The materials are entirely corrosion-resistant, featuring aluminum heat sinks. The electronic components are coated in synthetic materials, while the BI models come with diode casings.

Installation is easy due to the synthetic ends equipped with connection terminals, while the solid screw connections with nuts and retaining rings ensure quick installation.
