Bundle Components Explained
2 × Enerdrive B-TEC 100Ah Lithium Batteries
At the core of the setup are two 100Ah lithium batteries providing a combined 200Ah capacity. These batteries replace the earlier Enerdrive eLITE 100Ah models, improving performance with steady power output and longer cycle life. They are suited to powering a wide range of devices and appliances for mobile and off-grid users.
Enerdrive 40A DC2DC Battery Charger (EN3DC40+)
This charger plays a critical role by converting and regulating DC power from your vehicle’s alternator or solar panels to safely and efficiently recharge the battery bank. With up to 40 amps charge current, it maximises charging speed on the move or from other DC power sources.
Optional Enerdrive 20A and 40A AC Battery Chargers (EN31220 / EN31240)
For when you have access to mains shore power or a generator, these AC chargers convert grid electricity into DC current to recharge the batteries. The options of 20A or 40A charging provide flexibility depending on your power product details and desired charging speed while stationary.
How the System Works Together
The system is designed for maximum versatility. The DC2DC charger automatically manages charging from vehicle alternators or solar panels, ensuring your batteries stay topped up as you travel. When you’re parked with mains power available, the AC charger offers a convenient and efficient recharge option without taxing your vehicle’s electrical system.
This combination of DC and AC charging methods guarantees your battery bank remains reliably charged across a wide range of conditions, supporting comfortable and extended off-grid living or travel.
Additional Considerations
While this bundle provides the essential components for a robust lithium battery power system, it’s important to verify your specific needs and optional charger preferences directly on the merchant page. Installation requirements, warranty details, and compatibility with your unique vehicle or marine system should also be confirmed to ensure optimal setup and performance.
