Automatic dual-battery isolation for 24V rigs, with no switches to remember.
The REDARC SBI224D is a smart start battery isolator built for 24V vehicle and equipment systems running an auxiliary battery. It connects your start and auxiliary batteries when either one is being charged, then isolates them so accessories can never flatten your cranking battery. Because it is dual sensing, it responds to charge from the alternator or from a secondary source such as solar, making it a good fit for trucks and larger 24V setups rather than the more common 12V build.
- Dual sensing: detects a charge on either battery and links them automatically
- 200A continuous rating suited to heavy 24V loads and larger cable runs
- Fully automatic connect/disconnect with no manual switching
Note this is the 24V version; most builds are 12V, so confirm your system voltage before ordering. Pair it with the right cabling from our wiring accessories, or compare it against managed options in dual battery systems.
