Product Description

Enerdrive B-TEC 125Ah Lithium Battery, 5 Years Warranty. The Enerdrive B-TEC 12V 125Ah G2 Lithium Battery now comes with a Battery Strap. Enerdrive are proud to introduce the new ePOWER B-TEC 125Ah Lithium Battery with Smart Phone Monitoring Technology.

The ePOWER B-TEC 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 G2 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 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;

  • 125Ah Lithium = 200Ah 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 G2 battery is capable to be paralleled to a second G2 battery. For maximum performance and lifespan of your G2 battery, no more than 4 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.

*Note: As stipulated by the manufacturer Enerdrive, failure to charge the Enerdrive Lithium Battery range with an Enerdrive or Redarc Lithium Profile battery charger will void Enerdrive manufacturer warranty.

Great battery Review by
This is my second battery, which I have set up in parallel with my first. So reliable and charge quickly. Love the blue tooth connection. Now I can power everything in the caravan for days.

Super quick delivery, friendly and helpful phone s Review by
I bought the Enerdrive battery and a new charger over the phone. MyGenerator were happy to price match on the charger and arrange for me to pick it up the next day. so I could be ready for the battery. As planned, the battery arrived 2 days later. Perfect.

It ‘s Time Review by
Setec power distribution ceased to function, I read that as a sign to change the engine room of the caravan to lithium. Ab Fab battery, love the blue tooth SOC info, small foot print, cradle and strap a bonus. Something so small and yet so powerful. It is perfect for my needs, fast charge from solar, plenty of amps, runs everything including diesel heater. Love it!

Excellent delivery time, packaging and product wor Review by
I have been testing this battery over the last couple of days and while it was expensive, it is considerably lighter than 2 x 100 AH AGM batteries and charges a lot quicker. I have been running a 65L Waeco at 2 degrees (empty) and a Dometic 45L fridge as a freezer at -15 degrees (again empty). I have had the 2 fridges running constantly over 2 days and the battery is now only down to 70%. The Bluetooth monitoring app is good but could be improved by connecting automatically to the battery when you get in range. It is a bit of pain having to reconnect to it each time to see the condition of the battery. As for charging, when I first received the battery it was at 59% and voltage was a little down. However after driving for about 1 hour it was up to 100% and voltage was perfect. I am taking my truck across the Simpson, tomorrow so we will see how the battery performs over the next 2 weeks.

Product Q&A

Ask Us a Question
  • Do lithium batteries need to be ventilated? Any other install tips for my Enerdrive lithium battery?
    The batteries do not vent, so no need to be concerned about installing your Enerdrive Battery in a highly ventilated space.  
    It is recommended to keep them in a cool dry area to increase longevity. 
    Do not mount the battery on its side - it needs to be keep upright. Thanks.
  • I have a Tvan, which requires the battery to be mounted on its side.Will this void the warranty?

    Hi Chris,

    Thanks for getting in touch.

    Enerdrive do not recommend installing their batteries on their side.

    We would recommend giving them a call to discuss if installing it this way would cause any issues with warranty. Enerdrive can be reached on 1300 851 535.

  • Warranty . Thanks Rob Beer

    Hi Rob,

    The manufacturers warranty period for the Enerdrive 125aH lithium batteries is 2 years.

    As of 2020, all Enerdrive products now comes with a 5 Year Warranty. Any products purchased since 1st of January 2020, Enerdrive retrospectively applying the new 5 year warranty period.

  • Can I connect the Enerdrive B-tec Lithium Batteries in Parallel or in series?

    Hi there,

    You cannot connect any of the EnerdriveB-TEC batteries in series. You can however connect up to two only of the same size (ah) B-TEC batteries in Parallel. Enerdrive recommend that you only do this if you don't over load the max current of the internal BMS board from ONE OF THE BATTERIES.

    Example. If you connect 2 x 200Ah B-TEC batteries then do not draw more than 200A of DC current from that battery bank, as one (1) single 200Ah B-TEC battery is only capable of handling 200A DC.

    The main aim of connecting two (2) of the Enerdrive B-TEC batteries is not to increase your maximum DC current output, but to double your storage capacity.

    Double the storage equals double the time you can stay powered up and off the grid.

    Be sure to always consult the Enerdrive user manuals for correct cable sizing, fuse sizing and wiring diagrams.

    We now sell an Enerdrive battery bundle with a parallel kit - please CLICK HERE to find it.

  • Is it ok to install a enerdrive lithium battery under the bonnet of the a vehicle?If it is installed under the bonnet of a vehicle what damage could be done to the battery?

    Hi There,

    Enerdrive advise to never install any of their lithium batteries under the bonnet. The amount of heat produced in the engine bay can cause damage to the battery cells and would not be warrantied.

  • Would this battery be suitable for use in the Engel Battery box with the inbuilt DCDC charger?

    Hi There,

    This battery will fit in the Engel Battery box.

    The should not be an issue using them both together due to the battery boxes lithium charging capabilities.

  • Here in Australia the hot sun can raise the temperature inside a parked motor vehicle to above 60 degrees C. Is this of concern if I have a 60 litre Evacool fridge running using a 125 amp/hr Enerdrive Lithium battery?

    Hi There

    Power usage is dependent on several factors including (but not limited to): ambient temperature, required fridge temperature, temperature of fridge contents, compressor speed (fridge setting) and ventilation.

    At 32C, the average power draw would be approx 2 A/Hr. This would increase considerably at 60C.

    You would still likely get 24 hours usage off a 125ah battery.

    Kind Regards

  • I have a Cub with a Projecta Smart charger. Can I replace my AGM battery with a lithium, and still run the same charger. I also run solar for charging. Will a swap work, or do i need to start again?

    Hi There

    You can repalce your AGM with a lithium battery and keep the charger only if your charger is capable of charging lithium batteries.

    Without a proper charger you will damage your battery.
