ePOWER B-TEC 12V 200Ah Lithium Battery


ePOWER B-TEC LiFeP04 12v 200Ah Lithium Battery

Available in 12v 100Ah, 125Ah, 200Ah and 300Ah capacities and 24v & 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.

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.

Size & Weight Savings

Lithium v AGM Capacities;

  • 100Ah Lithium = 160Ah AGM
  • 125Ah Lithium = 200Ah AGM
  • 200Ah Lithium = 320Ah 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 7 years 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 over 3000 complete systems in operation Australia wide, Enerdrive is regarded as the leader in the field of lithium batteries and energy systems for Mobile, Marine and Remote applications.

Please Note; The B-TEC battery is capable to be paralleled to a second B-TEC battery of the same size. For maximum performance and lifespan of your 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 batteries BMS.

The 200Ah battery is able to accept a maximum inverter capacity of 2000W 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.
