Important note

Specifically engineered for 12V lithium battery applications, the SBI12-LLD safeguards your auxiliary battery by preventing deep discharge due to auxiliary loads. Its microprocessor control ensures precise operation, and built-in spike protection components minimize the risk of damage from voltage transients.

We accept
Suitable for use in 12V lithium (LiFePO4) battery systems across most 4WDs, caravans, camper trailers, and RVs. Ideal for dual battery setups or where lithium protection is essential.

The REDARC Smart Start SBI12-LLD Load Disconnect Isolator is a microprocessor-controlled device designed to protect lithium (LiFePO₄) auxiliary batteries from excessive discharge. It automatically disconnects non-essential loads when the battery voltage drops below a safe threshold, ensuring the battery remains above the level at which internal protection circuitry would activate. Once the battery voltage recovers, the isolator reconnects the loads, maintaining optimal battery health.
