Enerdrive ePOWER B-TEC 300Ah Lithium Battery
Available in 12v 300Ah capacity, the Enerdrive B-TEC G2 lithium battery is designed and intended for use in deep cycle applications where a single battery is required that meets the amp hour capacity.
Key Features:
- New design BMS
- Max discharge current 250A (15mins) - 200A continuous
- Max charge current 190A (30mins)
- Can be connected in parallel (up to 4 batteries)
- Built in flat battery reset button
- Includes mounting tray and 2 straps
- Communication ports (RS485) for future integration
- 5 year warranty & lifetime tech support
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 State of Charge (SOC) | Individual Cell Voltage |
| Battery Voltage | Battery State of Health (SOH) | Battery Temperature |
| Battery Current (Amps) | Battery Status | 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 |
Also included for free is a metal battery tray and hold down strap to complete the installation process.
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 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 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.
