Here's how these components work together:

  • B-TEC 2 x 300Ah Lithium Battery: The cornerstone of your energy storage system, boasting a 2 x 300-ampere-hour capacity. It serves as the primary source of electrical energy for various applications, such as RVs, boats, or other off-grid setups.
  • 40A DC2DC Charger: This charger plays a pivotal role in regulating and transforming incoming DC power from diverse sources, such as a vehicle alternator or solar panels. It efficiently channels power to recharge the battery, ensuring optimal performance with a maximum 40-amp charging current from DC sources.
  • 100A AC Charger: The AC charger recharges the battery when you have access to an AC power source, such as when your vehicle or setup is connected to shore power or an external generator. This charger converts AC power into DC power and delivers up to 100 amps to recharge the battery.
  • Inverter: The Enerdrive pure sine wave inverter plays a vital role in your setup. It ensures that the power delivered to your appliances and devices is of the highest quality. The pure sine wave output guarantees clean, stable power, making it suitable for sensitive electronics, ensuring they operate without interference or damage. This inverter enables you to use standard AC-powered devices with confidence, enhancing the versatility of your energy system.
  • Battery Monitor: A critical component providing real-time data on battery metrics such as voltage, current, state of charge, etc. It facilitates monitoring battery health for informed decisions about energy usage and recharging strategy.
  • MPPT: The solar charge controller plays a crucial role in maximizing the efficiency and performance of a solar power system by tracking the maximum power point of solar panels, optimizing energy harvest, managing battery charging, and providing monitoring and protection functions. It helps ensure that solar energy is harvested and utilized effectively, making it an essential component in off-grid, grid-tied, and hybrid solar power systems.

Pro Series to B-TEC - The Next Step for Enerdrive


Product Q&A

Ask Us a Question
  • 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.

  • With charge capabilities of 0°-45° does the btec battery have built in protection to stay within these perameters? Or does the Enerdrive dcdc40 charger have these protections built in to safeguard the battery?

    Hi There,

    The BMS built in to the battery has over temperature protection.

    It would be up to the user to make sure the battery is installed in an area where it should not be subject to temepratures under 0C and over 45C when being charged.


  • When putting Battery in its holding place, can i turn it on its side to slide it and then stand it upright

    Hi There,

    The Enerdrive Lithium Batteries are required to be stood upright. Enerdrive do not recommend placing them on their side at all, sorry.
