Enerdrive | Dometic B-TEC LiFeP04 24v 100Ah G2 Lithium Battery

Available in 12v 100Ah, 125Ah, 200Ah, 300Ah and 400Ah capacities and 24v 150Ah & 36v 100Ah, the ePOWER B-TEC lithium battery is designed and intended for use in deep cycle applications where a single battery is required that meets the amp hour capacity.

Smart Phone Monitoring System

The Enerdrive ePOWER B-TEC battery incorporates wireless Battery Monitoring Technology. By downloading the Android™ or Apple® app to your smartphone or tablet device, you can monitor the following information;

  • Battery Capacity
  • Battery Voltage
  • Battery Current (Amps)
  • Battery State of Charge (SOC)
  • Battery State of Health (SOH)
  • Battery Status
  • Individual Cell Voltage
  • Battery Temperature
  • Battery Cycles
  • Battery Alarms
  • Battery Event Information

Battery Management System

The battery is also equipped with an internal Battery Management System that can monitor and optimise each Prismatic cell within the battery during normal operation. It will protect the battery pack from over charge, over discharge, over temperature & short circuit. The BMS helps to ensure safe and accurate operation of the battery. Please note that a fully discharged battery (BMS is off) requires charging within 14 days to avoid cell damage.

Size & Weight Savings

Lithium v AGM Capacities;

  • 100Ah Lithium = 160Ah AGM
  • 125Ah Lithium = 200Ah AGM
  • 200Ah Lithium = 320Ah AGM
  • 300Ah Lithium = 480Ah AGM

(Based on standard depth of discharge for both Lithium (80%) and AGM (50%).

The ePOWER B-TEC battery provides 60% more usable power than its equivalent lead acid cousin and being nearly 50% lighter and 30% smaller makes for a superior alternative.

The ePOWER B-TEC battery is perfect for camper trailers, 4WD’s (AUX battery), caravans, small water craft, low power communication sites or any other application that requires the use of a single deep cycle battery that meets the amp hour capacity.

With over a decade of researching, designing and testing lithium batteries and the associated charging systems, Enerdrive are at the forefront of lithium battery systems in Australia. Enerdrive are the only Australian company that can supply a fully integrated self-branded energy system to suit your setup.

With thousands of complete systems in operation Australia wide, Enerdrive | Dometic is regarded as the leader in the field of lithium batteries and energy systems for Mobile, Marine and Remote applications.

Please Note; The ePOWER B-TEC battery is capable to be paralleled to a second ePOWER B-TEC battery of the same size. For maximum performance and lifespan of your ePOWER B-TEC battery, no more than 2 batteries should be connected together to increase your overall capacity. Overall loads when paralleled should not exceed the current limits of a single battery’s BMS.

The 150Ah battery is able to accept a maximum inverter capacity of 3500W only. Exceeding the maximum inverter capacity can damage the BMS Management within the battery.

If you are requiring a battery system larger than ePOWER B-TEC battery, please look at the Enerdrive Pro Series Power Pack Systems which can offer multiple parallel and series connections with Active Cell Balancing Protection across the entire pack.

This product is not suitable to mount anywhere with a possibility of being exposed to the elements. It is an electronic product designed for internal use ONLY.

2023 Standards Update: With some confusion regarding the up coming standards changes and how they will effect battery fitments for future builds including upgrades to existing builds, ENERDRIVE | DOMETIC have created a fitment guide. This guide is specific to our e-LITE and B-TEC range of batteries and has been designed to cover all portions of the battery installation requirements within the new standard. Please note this guide is specific to Enerdrive batteries and does not apply to any other manufacturer.

Charge Cycles Disclaimer:

The information provided regarding the life cycles of Enerdrive | Dometic lithium batteries is based on laboratory testing conducted under controlled conditions. These tests were carried out at a consistent temperature of 25°C, with discharge and charge rates set at 1C (1 x Capacity of battery).

Under these specific conditions, it has been calculated that our lithium batteries can achieve over 2500 cycles with approximately 80% of original capacity remaining. However, it’s essential to note that actual performance may vary depending on various factors, including but not limited to, installation environment, temperature fluctuations, and variations in discharge and charge rates.

It is recommended to avoid excessive discharges and charge cycles and to maintain a discharge and charge rate around 0.5C (0.5 x Capacity of battery) for optimal battery longevity. Doing so may result in a significantly higher cycle count.

Please be aware that the numbers provided are based on cell-level testing and may not directly reflect the performance of your specific battery installation. As such, we advise users to consider their individual circumstances when assessing the expected lifespan of their batteries.

Even in the scenario of reaching 2500 cycles, it’s important to understand that the lifespan of the batteries can extend beyond this figure. For instance, if batteries were fully discharged daily, a lifespan of over 6.8 years could still be expected. If you don’t normally take the battery under normal use below 30% SOC, then you could find that the battery will continue to meet your needs for many cycles to come.

For further guidance on maximising the performance and longevity of Enerdrive | Dometic lithium batteries, please consult our technical support team or refer to the user manual.
