Product details

The REDARC Smart Start SBI24D is a dual battery isolator that is easy to install and is used to isolate start and auxiliary batteries in a dual battery system. It protects the start battery from a low charge in the secondary battery so it won't drain the primary battery. The SBI24D provides 24 volt DC incorporating 100A of continuous ratings. The dual sensing model isolates the start and auxiliary batteries in a system where the auxiliary battery may also be charged by solar panels or another external source. It also allows the start battery to be charged from the external source once the auxiliary battery reaches 26.4 volts. Power saving technology includes components which prevent the solenoid from generating high voltage transients. Sophisticated fault detection and LED indication of operation alerts the user of over-voltage, voltage drop, and excessive current draw conditions. The Smart Start SBI24D is surge protected and a safe way to charge auxiliary batteries. It's primarily used in commercial vehicles. The SBI range manages battery charge for your secondary battery banks while on the move. The SBI24D provides 24 volt DC incorporating 100A of continuous ratings. Bat. Isolator Dual24V100A

BEFORE YOU ORDER

A few things to know.

How do I order these parts?

Add your exact parts and delivery details, then continue to payment. Eligible orders show the final parts, shipping and tax total and a PayPal button here after automatic checks. Freight, oversized, custom and uncertain items go to JuiceBuilt for a quote. You are charged only after approving PayPal; supplier orders are submitted separately after verified payment.

Does a part number guarantee vehicle fitment?

No. Product descriptions are supplied by the manufacturer. Check the manufacturer application information for your exact vehicle, engine and supporting modifications. Online checkout requires your exact-part fitment acknowledgment. Contact JuiceBuilt before ordering if you need fitment help.

Is the stock shown reserved for me?

No. Availability is a dated supplier snapshot. Inventory can change, and adding a part to your build does not reserve it. Availability and delivery are checked again before payment. A supplier order is confirmed separately after payment.

What about shipping?

Eligible standard-size parts orders with a parts subtotal of $100 or more receive free standard shipping.

The same $100 minimum applies to all brands, including Aerospace Components.

Oversized and freight items are excluded from free shipping at every subtotal, including carbon doors, hoods, trunks and similar large panels. Their shipping charge is quoted separately before payment.

Shipping for orders below $100 is quoted in your reviewed estimate before payment.

Online checkout is initially available for US delivery addresses. For other countries, contact JuiceBuilt for a manual quote before payment.
