Smart Phone Monitoring System
The Enerdrive 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 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 G2 = 320Ah AGM
- 300Ah Lithium G2 = 480Ah AGM
(Based on standard depth of discharge for both Lithium (80%) and AGM (50%).
The Enerdrive B-TEC G2 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 Enerdrive B-TEC G2 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.
The New Generation 2 B-TEC
So, How does the New Enerdrive Generation 2 (G2) B-TEC 300Ah Lithium Battery measure up against it original predecessor? Let’s have a look
Dimension Original Generation 2
| Length | 519mm | 521mm |
| Width | 273mm | 280mm |
| Height | 222mm | 238mm |

The G2 now incorporates a “Built-In Reset Button” making re-starting a flat battery a breeze. No longer do you need to apply a voltage to the battery terminals to wake up the battery. Press the button and within seconds, the battery will come back to life ready to accept a charge source to rejuvenate the battery.
The new G2 also includes a RS485 communications port located on the top of the battery. This port allows for integration onto other CanBus systems for data monitoring and recording.
The New Enerdrive Generation 2 (G2) B-TEC 300Ah Lithium Battery now comes with a 5 year warranty, giving you peace of mind that this product will keep you covered.
With over 8 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 4000 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.
The G2 300Ah battery is able to accept a maximum inverter capacity of 3000W only. Exceeding the maximum inverter capacity can damage the BMS Management within the battery.
If you are requiring a battery system larger than the Enerdrive B-TEC G2 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.

Product Q&A
-
Can you series link these batteries to create a 300amp 24v system?Also, the 40amp dc2dc charger is that capable of charging 12v input to 24v output?
Hi There,
Enerdrive have advised that none of their batteries can be connected in series.
In regard to the DC DC charger, the 12V model will only output 12V. Enerdrive make a 30A 24V model. You can find it here:
https://www.mygenerator.com.au/enerdrive-epower-24v-30a-dc-to-dc-battery-charger.html
-
I notice that the specs say the recommended charging current for the 300ah BTEC is 80-120amps. Do you still see many people use the Enerdrive ePOWER 40A AC Battery Charger for the 300ah BTEC?
The 80 - 120A values are the nominal charge rates, not recommended charge rates. Using the 40A charger is fine as you will not always be recharging the full 300Ah, just the bit you have used, so yes, we do have many people still using it for 300BTec batteries
-
Can I series connect B-TEC batteries to achieve higher voltage?
No. Enerdrive offers higher voltage Lithium solutions - contact us for details.
-
Can I use an Inverter with my B-TEC battery?
Yes. Refer to Section 4 of the manual for more detail.
-
Can I install the B-TEC battery in a wet area?
No. Due to the construction of the B-TEC cases the batteries must be installed in a dry environment to protect against moisture ingress.
-
Can I parallel B-TEC batteries?
The short answer is yes. The long answer is - make sure the link cables are of the same size or greater than your load/charging requirements and no more than 4 batteries in parallel.
With low to medium current draw installations (the vast majority of applications) you may never see an issue and your storage capacity will be greatly increased - I.E. 2 x 200 Amp = 400 Amp capacity. When installing, fully charge the batteries separately - then let sit for 30 minutes before connecting together. When connecting in parallel - take the positive from Battery 1, and the negative from Battery 2 to your system as per the diagram below.
The Smart Phone App will only show the information from one battery at a time - not both. This is another advantage of a separate Battery Monitor - it will show the total system environment.
*Note: Slight variance of State of Charge or Amps may occur between the batteries in parallel however these should not vary by more than 5%. It is recommend that annually the batteries be disconnected and individually charged allowing them to sit at a fully charged state for 12hrs each before connecting back together.
-
Can I install the B-TEC battery on its side or end?
No. Please note that the 12V 200Ah SLIM B-TEC Battery features a wider range of acceptable mounting orientations - please refer to the diagram below for guidance.
-
Q: What size terminals do I need to screw on the Enerdrive 300ah Lithium Battery?
The Enerdrive 300ah lithium battery requires 8mm post terminals. The terminals are bolted onto the battery terminal bolt using spring washers.
Customer Reviews
300AH Enerdrive “the beast” Review by MartinI just love the Enerdrive batteries, the Bluetooth connectivity is amazing and allows. Excellent connectivity and tells you exactly what the battery is up to. This 300Ah Enerdrive is a beast, enough to power the van for a couple of days no charge and you can hook the induction cook top up and bang in combination with the 2000w inverter it just works.(Posted on 4 August 2023)
Excellent battery, excellent service. Review by Grant PalmerThis 300 ah lithium battery is everything I had hoped for. I've now installed it in our off road camper and it's performing perfectly. Instillation was very straight forward. A full night's draw uses only 8%of the capacity.It has bluetooth connectivity that is giving me all the info I need. I've tested the Bluetooth data against my multitesteter and it's very accurate.(Posted on 26 November 2022)
