The SBI12-LLD is a microprocessor-controlled Load Disconnect Isolator. The SBI12-LLD is designed specifically for use in LiFePO4 battery applications as a system to protect the lithium battery from being excessively discharged by auxiliary loads, enabling the auxiliary battery to remain above the level at which internal protection circuitry would activate. Falling below this threshold would prevent many chargers from recharging the battery.
