Lithium Innovation – Enerdrive 400Ah Slimline

Experience the power of the Enerdrive 400Ah Slimline Lithium Battery, a ground breaking solution for deep cycle applications that demand high amp hour capacity in a compact package.

Measuring a mere W 630mm x H 498mm x D 216.5 mm, this battery offers unmatched size efficiency. All connection points, including Comms Ports and Reset Port, are conveniently located at one end, ensuring a streamlined installation process.

The innovative reset button, positioned remotely for ease of access, simplifies the restart procedure and enhances water resistance, reducing the risk of water ingress. Comms Ports, both equipped with RJ45 connections and CAN output, are reserved for future integration and expanded functionality.

Constructed within a water-resistant metal casing that meets an IP52 rating, this battery employs blind external bolts and fittings, effectively preventing water infiltration. Rubber-style seals and overlapping frames further bolster its water resistance.

Experience smart monitoring with the Enerdrive 400Ah Slimline battery, which integrates wireless Battery Monitoring Technology.

Download the Android™ or Apple® app to your smartphone or tablet to access a wealth of information, including Battery Capacity, Voltage, Current, State of Charge, State of Health, Status, Individual Cell Voltage, Temperature, Cycles, Alarms, and Event Information.

Advanced Battery Management

Equipped with an internal Battery Management System (BMS), this battery optimizes each Prismatic cell during normal operation. The BMS safeguards against overcharge, overdischarge, overtemperature, and short circuit. Please note that a fully discharged battery requires charging within 14 days to avoid cell damage.

Size and Weight Efficiency

Compare lithium to AGM capacities, and you’ll discover the superiority of the Enerdrive B-TEC battery. It provides 60% more usable power than its lead acid counterpart, all while being nearly 50% lighter and 30% smaller.

The Enerdrive B-TEC Slimline battery is perfect for camper trailers, 4WDs (AUX battery), caravans, boats and watercraft, off-grid battery applications, or any application requiring a single deep cycle battery with large capacity.

Leaders in Lithium Battery Systems

With over 7 years of research, design, and testing in lithium battery systems, Enerdrive leads the way in Australia.

The Enerdrive 400Ah Slimline Lithium Battery can be paralleled with a second B-TEC 12V 400Ah Slimline Lithium Battery, but no more than 4 batteries should be connected together to maintain overall capacity within safe limits.

The 400Ah Slimline battery is compatible with a maximum inverter capacity of 3000W. Exceeding this limit can damage the BMS Management.

Avoid installing B-TEC batteries in vehicle engine bays, high-heat environments, wet areas, or compartments designated for gas storage. These batteries are designed for internal use only.
