Mastervolt BI 1202-S charging current distributor 83012021

The Mastervolt BI 1202-S is a compact battery isolator for onboard systems with multiple batteries. Using diode technology, it reliably distributes the charging current to separate battery banks; the voltage drop of approximately 0.6 V can be compensated by the battery charger or alternator. The corrosion-resistant housing with aluminum heat sink and encapsulated electronics ensures a durable and clean installation.
