Mastervolt Battery Isolator BI 1202-S

Mastervolt Battery Isolator BI 1202-S in Dubai

Most boats run more than one battery, usually a starting battery for the engine and a service battery for lights, pumps and electronics. The Mastervolt BI 1202-S battery isolator lets one alternator or battery charger charge two battery banks at the same time while keeping them separated. If the service battery runs flat at anchor, your starting battery stays full. SEA ONE MARINE supplies this marine battery isolator in Dubai and across the UAE.

About Voltage Drop

Diode isolators have a small voltage drop of about 0.6V. To fully charge your batteries, this is compensated by raising the output voltage of the alternator or charger. Mastervolt chargers and Alpha Pro MB charge regulators handle this compensation automatically, making them a good match for the BI series.

Installation Advice

Then, mount the isolator in a dry, ventilated place so the heat sink can cool, and use correctly sized marine cable and fuses. If you are unsure about the right isolator rating for your alternator, send us your engine and battery details and our team will recommend a suitable model.
