About Enerdrive
Enerdrive Pty Ltd has been providing independent power systems to the Australian market since 1996. Starting as Advance Trident Limited in 2003 and predominantly servicing the marine industry, ATL saw the huge growth potential in the mobile and recreational vehicle market soon after, and in 2008 ATL Limited morphed into Enerdrive. In recent times Enerdrive has embarked on its own manufacturing program. They saw the need to control their own destiny and produce high-end products that the Australian marketplace was demanding. This program has led to Enerdrive manufacturing their own range of ePOWER AC Battery Chargers & DC2DC Battery Chargers along with Lithium battery systems.

Lithium batteries use lithium iron phosphate (LiFePO₄) chemistry to store and release energy. They work by moving lithium ions between the positive and negative electrodes during charging and discharging. Compared to traditional lead-acid batteries, lithium batteries deliver more usable energy, faster charging, and a longer lifespan in a lighter package.
Lithium batteries offer several key benefits:
- Up to 50% lighter than AGM batteries
- Longer cycle life (often 2,000–5,000+ cycles)
- Faster charging and higher efficiency
- Deeper discharge capacity (up to 100% usable energy)
- Low self-discharge rate, perfect for long-term storage
These advantages make them ideal for 4WDs, caravans, campers, and off-grid solar systems across Australia.
In most cases, yes. Lithium batteries can replace AGM or lead-acid batteries in 12V and 24V setups, provided your charger or regulator supports lithium charging profiles. If you’re unsure, check that your DC-DC charger, solar controller, or mains charger has a LiFePO₄ mode to optimise charging and maximise battery life.
A high-quality lithium battery can last 10–15 years or more, depending on usage and environment. Most offer 2,000–5,000+ charge cycles, meaning you can enjoy years of dependable power for camping, boating, or off-grid living and can far outlast traditional lead-acid batteries.
Yes. Lithium batteries can be connected in parallel (to increase capacity) or series (to increase voltage), for example, wiring two 12V batteries in series to create a 24V bank. Always ensure the batteries are the same brand, model, and age, and that your charger and BMS support the configuration.
You’ll need a lithium-compatible charger or solar controller with a LiFePO₄ charge profile. These chargers use the correct voltage settings (typically around 14.2–14.6V per 12V module) and ensure safe, efficient charging. Using the wrong charger can reduce performance or damage the cells.
Absolutely. LiFePO₄ batteries are designed to perform in hot and demanding environments, making them perfect for Australian off-grid and travel setups. They tolerate high temperatures better than most battery types, have low self-discharge, and are vibration-resistant making them ideal for 4WD, caravan, and marine use across Australia.
