Enerdrive 12V 300Ah B-TEC Ultra IP67 Waterproof Lithium Battery

High-Capacity Lithium Power for Demanding Off-Grid and Mobile Applications

The Enerdrive B-TEC Ultra 12V 300Ah Lithium Battery delivers robust, long-lasting energy for caravan, RV, marine, off-grid, industrial, tiny home, and 4WD setups. Designed for users who require dependable power in harsh environments, this 300Ah lithium battery combines advanced safety, rugged construction, and high-output performance in a single premium solution. With a 1000A peak discharge and 300A continuous output, it effortlessly powers inverters, induction cooktops, air conditioners, and other high-draw appliances, making it a top choice for those seeking a high-capacity 12V lithium battery for caravan and off-grid systems.

IP67 Waterproof and Dustproof: Built for the Outdoors

Engineered to withstand Australia’s toughest conditions, this IP67 waterproof lithium battery is fully sealed against dust and can handle temporary water immersion. This makes it ideal for external mounting on caravans, camper trailers, 4WDs, and marine vessels, where exposure to rain, dust, and mud is common. Unlike standard batteries that may fail in wet environments, the B-TEC Ultra’s sealed design reduces the risk of corrosion and electrical faults, ensuring reliable operation in coastal and off-road settings.

Advanced Battery Management and Safety

At the core of the B-TEC Ultra is a sophisticated Battery Management System (BMS) that provides comprehensive protection against overcharge, over-discharge, short circuits, and temperature extremes. The integrated heater enables charging in temperatures as low as -20°C, a critical feature for cold-climate adventures where standard lithium batteries may fail. This heated lithium battery ensures consistent performance year-round, reducing the risk of downtime during winter trips.

Smart Monitoring via Bluetooth

Stay informed with Bluetooth battery monitoring through the Enerdrive app. View real-time data on state of charge, voltage, current, and individual cell diagnostics directly on your smartphone. This smart connectivity allows you to manage your power usage proactively, avoiding unexpected depletion and extending battery life. The app also provides access to technical guides and support, enhancing user confidence.

Long Cycle Life and Low Total Cost of Ownership

With a cycle life of 6,000 cycles at 80% depth of discharge, this deep cycle lithium battery significantly outlasts traditional lead-acid alternatives. Its high efficiency and low self-discharge rate mean more usable energy and fewer replacements over time, reducing long-term costs. For off-grid solar systems, the B-TEC Ultra’s ability to handle frequent deep cycling without degradation ensures dependable power for years.

Flexible Installation and Expandability

The battery includes a mounting tray and heavy-duty straps for secure installation in vehicles or fixed locations. Dual M8 positive and negative terminals (tightening torque 8-10 N·m) accommodate high-current connections, while the M12-6P communication ports support CAN and RS485 protocols for integration with advanced energy systems. The ability to connect up to 4 batteries in series and 4 in parallel allows you to build a customised power bank for 24V, 48V, or high-capacity 12V setups, solving the problem of limited expandability found in many generic batteries.

Certified Quality for Peace of Mind

Backed by IEC62619 certification, this battery meets stringent international safety standards for industrial and mobile applications. The 5-year warranty underscores Enerdrive’s confidence in its durability and performance, reducing the risk of premature failure that can plague lesser-quality products.
