Designed and engineered in Australia by Enerdrive, this advanced lithium battery offers a perfect blend of compact size, robust build, smart technology, and long-lasting capacity — ideal for those who demand quality and dependability in their energy systems.
What Makes the Enerdrive B-TEC 400Ah Slim Metal Case Lithium Battery Special?
The Enerdrive (EPL-400BTM-12V) is a standout lithium battery thanks to its smart design tailored for deep cycle applications where a single, reliable battery must deliver solid amp hour capacity. Let’s explore the features that make this battery a great investment for Australian outdoor enthusiasts and professionals alike.
Compact, Durable, and Water-Resistant
Measuring just 630mm wide, 498mm high, and 216.5mm deep, the battery’s slim metal case fits easily into tight spaces, making it perfect for camper trailers, caravans, 4WD auxiliary systems, and small boats. Its IP52 water-resistant metal casing features rubber seals and overlapping frames to prevent water ingress, while all external bolts are blind-fitted to further protect the internal components.
Smart Battery Management System (BMS)
Safety and battery longevity are paramount. The internal Battery Management System monitors each prismatic cell individually, protecting the battery from overcharge, over-discharge, overheating, and short circuits. This ensures reliable, safe operation over thousands of cycles.
Wireless Monitoring via Smartphone
One of the innovative highlights of the Enerdrive B-TEC 400Ah Slim Metal Case Lithium Battery is its wireless Battery Monitoring Technology. Using Enerdrive’s Android™ or Apple® app, users can remotely check battery capacity, voltage, current, state of charge (SOC), state of health (SOH), temperature, individual cell voltages, cycle count, and receive alarms or event information. This level of insight helps you manage your power system effortlessly, right from your phone or tablet.
Performance and Capacity: Lithium vs AGM
The Enerdrive B-TEC offers significant benefits over traditional AGM batteries. Thanks to lithium’s chemistry and efficient design, it delivers:
- 60% more usable power than lead-acid equivalents, due to a higher depth of discharge (80% vs 50%).
- Nearly 50% lighter weight, making it easier to handle and reducing overall vehicle load.
- 30% smaller footprint, perfect for limited space installations.
Here’s a quick comparison of lithium to AGM capacity for context:
| Lithium Battery Capacity | Equivalent AGM Capacity |
|---|---|
| 100Ah | 160Ah |
| 125Ah | 200Ah |
| 200Ah | 320Ah |
| 300Ah | 480Ah |
Applications: Where the Enerdrive B-TEC Slimline Battery Excels
The Enerdrive (EPL-400BTM-12V) is versatile and suited for a range of uses, including:
Camper Trailers & Caravans
Compact size and high capacity make it ideal for powering fridges, lights, and devices on the road.
4WD Auxiliary Battery
Provides dependable power for winches, lighting, and camping gear without adding excessive weight.
Marine & Small Watercraft
Water-resistant casing and robust electronics suit the challenges of marine environments (excluding direct exposure to elements).
Installation and Safety Considerations
The Enerdrive B-TEC 400Ah Slim Metal Case Lithium Battery is designed for internal use only and must be installed in a dry, ventilated space away from direct exposure to heat or moisture. Please note these key guidelines:
- Do not install in engine bays, wet areas such as caravan chassis mounts, open ute trays, or boat decks.
- Keep away from compartments carrying gas.
- Up to four batteries may be connected in parallel to increase capacity, but total loads must respect the single battery’s BMS limits.
- Maximum inverter capacity supported is 3000W; exceeding this risks damage to the battery.
