Shipping Policy

This kit has a 7 business day fulfilment time. This means your order will be picked, assembled (if required), and prepared for dispatch within seven business days of purchase.

Once dispatched, you will receive a tracking number via email so you can monitor the progress of your delivery.

Estimated delivery timeframes within Australia:

• Standard Shipping: 5–7 business days
• Express Shipping: 3–5 business days

Please note:

• Delivery timeframes are estimates and may vary depending on your location and the shipping carrier.
• Delivery timeframes do not include the 7 business day fulfilment time.
• Tracking updates may take time to appear after dispatch while the carrier processes the shipment.
• Once your order has been dispatched, it is in the hands of the shipping carrier. For delivery updates, delays, or enquiries, we recommend contacting the carrier directly using your tracking number.

Lithium Battery and Dangerous Goods Shipping

If you purchase a dual battery kit that includes a lithium battery, the shipment will be classified as Dangerous Goods and sent via TNT/FedEx.

The lithium battery and the remainder of your kit may be packed separately and may arrive at different times, even though they are travelling under the same tracking or consignment number.

Dangerous Goods shipments must pass through additional handling and safety checkpoints while in transit. They may be temporarily held at these checkpoints for processing, which means we cannot provide an exact delivery date or ETA. Tracking updates may also pause for a period while the consignment is being processed.

These delays are part of TNT/FedEx’s Dangerous Goods transport process and are outside our control. Please continue monitoring your tracking information or contact the carrier directly for the latest available update.

We take care to ensure your order is securely packaged, correctly declared and dispatched as quickly as possible.

The customer is responsible for all return shipping costs.

Does this kit work with the Accelerate inverter/compressor bracket for the Prado 250?

Yes. This underfloor kit is designed to work perfectly with our inverter/compressor bracket system.

If you purchase both together, we will pre-mount the inverter mega fuse onto the battery tray for you to make installation even easier.

Can I run socket banks on both sides of the vehicle?

Yes. Simply add the Dual Socket Upgrade (add-on product) to your order.

This includes the Prado-specific Y-lead that safely connects both socket banks to the underfloor system.

Are instructions included with the kit?

Yes. Every kit comes with a full installation video and a detailed PDF instruction manual including wiring diagrams, photos, and step-by-step guidance.

Do I need to run any cabling from the engine bay to the rear?

No. This is a self-contained underfloor system.

All charging, fusing, solar input, and output wiring is located in the rear of the vehicle — there’s zero cabling run through the vehicle.

Does the REDARC Alpha 50A work in the Prado 250?

Yes — when limited to 40A.

We pre-program the Alpha 50A to a 40A limit, making it fully suitable for the Prado 250 while still offering faster charging and jumpstart capability.

Will this fit with drawer systems?

This kit is:

• Compatible with RV Solutions (RVSS) drawer systems
• Not compatible with the RVSS false floor (battery height clearance)
• Not yet tested with other aftermarket drawer or false-floor systems

Does this kit work in both 5-seat and 7-seat Prado models?

Yes. The tray and wiring loom are designed to work with both seating configurations.

Will the 220Ah battery fit under the factory floor without raising it?

Yes. The custom tray is engineered specifically to house the underfloor 220Ah battery while retaining the factory floor height.

Does my Alpha DC-DC charger have temperature protection?

Yes. The Alpha DC-DC charger has intelligent thermal protection built in.

• If the internal temperature exceeds ~55°C, the charger will gradually reduce output to protect internal components.
  
• If the internal temperature reaches ~80°C, the charger will fully shut down to prevent damage.

Once temperatures return to a safe operating range, normal charging will automatically resume.
