THE SMART START

SBI

The Smart Start

SBI is a microprocessor controlled Smart Battery Isolator. The Smart Start

SBI is

designed speciﬁ cally for use in multi battery applications as a solenoid priority system to protect 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.
