FAQs

I thought you couldn’t put lithium batteries under the bonnet?

You're right, most lithium batteries can’t go underbonnet. However, the Invicta Xero range is specifically rated and warranted for under-bonnet use. The internal BMS protects the battery by switching it off when it gets too hot and turning it back on once it cools. It’s super safe, and we’ve installed over 400 of these kits, both DIY and in-house here at our workshop in Maroochydore.

Can I add towing gear like an Isolated Anderson Plug, ESC, Tow-Pro, or a trailer bracket to this kit?

Absolutely. Just add those accessories when ordering and we’ll modify the kit to suit, including fusing, routing, and pre-wiring where needed so it’s all ready to go in one seamless install.

3I have a GR Sport with the honeycomb grille. How do I plug in solar if I can’t go through the grille?

No problem, just choose either the under-bonnet solar plug option or roof-mount solar input when checking out. You can still run a portable panel through a red Anderson plug mounted to your roof rack or wherever works best on your setup.

4Can I upgrade to the REDARC Alpha charger for jumpstart and start battery support?

Yes, we offer a separate kit built specifically around the REDARC Alpha charger, which gives you Bluetooth app control, start battery maintenance, and a jumpstart function. [Click here to see our LC300 Underbonnet Kit with Jumpstart Feature.]

5. Does this kit work with the factory battery and my existing setup?

Yes, this system mounts beside your factory start battery and works independently with your lithium auxiliary. It integrates seamlessly with your factory wiring, and you can still add solar, towing gear, or other accessories.

6. How hard is the install, can I do it myself?

This is one of our most DIY-friendly kits. It includes detailed PDF instructions, a full YouTube video walkthrough, and pre-wired looms that plug into factory bolt locations. No cutting, splicing, or guesswork needed.
