Professional installation is available through Elevate Automotive in Bayswater, WA.

This battery can be mounted horizontally in appropriate spaces with vibration isolation. Please follow supplied orientation guidelines or contact us for advice.

Designed for tight-fit installations in 4WDs, utes, vans, and canopies.
Perfect for setups requiring a compact, slimline lithium battery.

Q: Can I mount this battery lying flat?
A: Yes, the Slim 12V battery can be mounted flat or on its side as long as it is securely fixed and vibration-protected. Always refer to the included orientation guide for best results.

Q: Can I run a 240V inverter off this battery?
A: Absolutely. Both the 100Ah and 200Ah models support high discharge loads suitable for powering a 240V inverter, making them ideal for camping setups, canopies, and mobile workstations.

Q: Is this battery compatible with my DC-DC charger?
A: If your charger has a lithium profile (bulk charge 14.2–14.6V, float 13.4–13.6V), it’s compatible. Most Victron, Redarc, and Enerdrive chargers support these settings—just double-check your model.

Q: Can I use this to replace an AGM battery?
A: Yes, but ensure your system supports lithium charging voltages. AGM and lithium require different charge profiles, so check your DC-DC, solar, and AC charger specs before swapping.

Q: Does it come with mounting hardware?
A: No, mounting hardware is not included. However, we recommend vibration-dampened mounting and secure strapping for best performance in off-road conditions.

Q: Is it safe to use in extreme heat or cold?
A: The battery operates between -20°C and 60°C. It’s well-suited to the Australian climate and has built-in protection against overheating and over-discharge.

Q: What terminals does this battery use?
A: Both the 100Ah and 200Ah models use M8 terminals for secure, high-current connections.
