PRODUCT FUNCTION
The Smart Start
®
SBI is a microprocessor controlled Smart Battery Isolator and is designed specifically for use
in multi battery applications as a solenoid priority system. It protects the start battery from being excessively
discharged by auxiliary loads, whilst still allowing the auxiliary battery to supply non essential loads.
Put simply, once the start battery has had some charge from the alternator, the Smart Start
®
SBI will connect
an auxiliary battery to the charge circuit. Similarly, if the start battery voltage drops too low, the Smart Start
®
SBI
will disconnect any auxiliary batteries or loads from the start battery to conserve charge.
