Enerdrive 12V 125Ah ePower B-TEC Lithium Battery G2

DESCRIPTION

Enerdrive 12V 125Ah ePower B-TEC G2: Intelligent Lithium Energy Storage

The Enerdrive 12V 125Ah ePower B-TEC Lithium Battery G2 represents a significant leap forward in portable power storage. Designed specifically for deep cycle applications, this advanced LiFePO4 power source provides a reliable, lightweight alternative to traditional lead-acid systems. Whether you are outfitting a camper trailer, caravan, or a remote communication site, the B-TEC G2 delivers consistent voltage and high-capacity storage to keep your essential 12V appliances running efficiently off the grid.

Wireless Smartphone Monitoring

Take the guesswork out of your energy management. The Enerdrive B-TEC G2 features integrated wireless monitoring technology, allowing you to track your system's performance directly from your Apple or Android smartphone or tablet. By simply scanning the QR code and downloading the app, you gain real-time access to critical data, including:

  • Battery state of charge (SOC) and state of health (SOH)
  • Current voltage and current flow (amps)
  • Individual cell voltage and internal battery temperature
  • Active alarms and diagnostic event information
  • Cycle count for long-term health tracking

Advanced Battery Management System (BMS)

Safety and longevity are at the core of the B-TEC G2 design. The internal Battery Management System continuously monitors each prismatic cell, optimising performance during normal operation. This intelligent system safeguards the unit against overcharging, over-discharging, extreme temperatures, and short circuits. If the BMS triggers a shutdown due to low voltage, the Generation 2 model features a highly convenient built-in reset button. A simple press instantly wakes the system, allowing you to apply a charge source without the need to manually jump or bridge terminals.

Significant Size and Weight Savings

Upgrading to lithium offers unparalleled efficiency compared to traditional AGM setups. A standard 125Ah lithium unit provides the equivalent usable energy of a 200Ah AGM unit, based on standard depth of discharge rates (80 percent for lithium versus 50 percent for AGM). The Enerdrive B-TEC G2 provides up to 60 percent more usable power than its lead-acid cousin while being nearly 50 percent lighter and 30 percent smaller. This frees up valuable cargo capacity and reduces the payload strain on your vehicle or watercraft.

Generation 2 Enhancements

The Generation 2 B-TEC builds on the success of its predecessor with several targeted improvements to streamline installation and connectivity. The casing has been slightly increased in height (now measuring 265mm), which allows for full 360-degree connection of battery cables, making tight installations far more manageable. Additionally, the new RS485 communication port on top of the unit enables seamless integration with CanBus systems for advanced data monitoring and recording. To complete the package, Enerdrive includes a custom metal battery tray and a heavy-duty hold-down strap.

Important Installation Guidelines

To ensure optimal performance and maintain the integrity of the system, please observe the following technical parameters:

  • Parallel Connections: Capable of being paralleled up to a maximum of four units to increase overall capacity. Overall loads must not exceed the current limits of a single unit's BMS.
  • Inverter Capacity: This 125Ah unit supports a maximum inverter capacity of 1000W. Exceeding this limit can damage the internal BMS.
  • Environmental Limits: Strictly designed for internal use. Do not install in vehicle engine bays, wet areas like open ute trays or boat decks, or inside compartments dedicated to carrying gas.

Power Your Next Adventure

With years of proven performance in the demanding Australian environment, Enerdrive delivers a storage solution you can depend on. Upgrade your 12V system with the Enerdrive 12V 125Ah ePower B-TEC G2 and enjoy efficient, intelligent, and long-lasting energy storage. Order yours today to experience the true potential of lithium power.

It is not an attempt by Enerdrive to void any warranty obligations, however considering a large proportion of product issues are related to installation or system-based problems of some nature, it’s ensuring that an Enerdrive product is installed and used correctly as originally intended. All Enerdrive products have an installation manual which shows the requirements for installation, with ‘Industry Best Practice’. Installations shall be compliant to relevant standards including but not limited to AS/NZ 3001 (Electrical Installation Transportable Structures) and AS/NZ 3004 (Electrical Installation Marinas and Boats)
