Product details

?The REDARC Smart Start SBI224D is primarily used in commercial vehicles to protect the start battery from excessive discharge and provides 24V DC, while incorporating 200A of continuous ratings. This dual sensing model allows charging of batteries in instances when the auxiliary battery may also be charged by an external source, such as an external AC battery charger or solar panels. When the auxiliary battery reaches 26.4V from its external source, the SBI224D will then charge the start battery as well. Additionally, the microprocessor-controlled battery isolator has power saving technology that prevents the solenoid from generating high voltage transients. It is used rather than a diode battery isolator due to the voltage drop associated with diode type isolation. Advanced fault detection warns the user of over-voltage, voltage drop, and excessive current draw conditions. When the auxiliary battery reaches 26.4V from its external source, the SBI224D will then charge the start battery as well. Bat. Isolator Dual24V200A

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.
