Circuit Protection
The battery is supplied with a LiFePO4 Battery Management System (BMS) that can monitor
and optimize each single prismatic cell during charge & discharge, to protect the battery
pack from overcharge, over discharge & short circuit. Overall, the BMS helps to ensure safe
and accurate operation of the battery.

Battery Management System
The battery is also equipped with an internal LiFePO4 Battery Management System (BMS) that
can monitor and optimize 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 / 2005Ah Lithium = 360Ah 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 5 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 1200 complete systems in operation Australia wide, Enerdrive is regarded as the leader
in the eld of lithium batteries and energy systems for Mobile, Marine and Remote applications.
PLEASE NOTE; The ePOWER B-TEC battery is not designed to parallel connect extra batteries to
increase the overall capacity. This is due to the internal management system (BMS) which does
not have the ability of physical connection to a second B-TEC BMS system for balancing of the cells
between each battery.
If you are requiring a battery system larger than the ePOWER B-TEC 100Ah, 125Ah or 200Ah battery,
please visit www.enerdrive.com.au and look at the Enerdrive Lithium Power Pack Systems which
can oer this level of cell balancing protection.
