Product Description

Enerdrive B-TEC 2 x 200Ah Lithium Battery, Charger, Inverter & Monitor Bundle, 5 Year Warranty. The Enerdrive 2 x 200Ah lithium battery, when used in combination with a 40A DC-to-DC charger, is typically part of a setup commonly used in various applications, including off-grid power systems, recreational vehicles (RVs), boats, and other mobile power needs.

The AC charger becomes relevant when you are connected to an AC power source, such as a campsite with electricity hookups or a marina with shore power. It provides a convenient means to recharge the battery when AC power is available.

Bundle Includes:

Optional AC Charger:

  • EN31260 - Enerdrive 60A AC Battery Charger
  • EN312100 - Enerdrive 100A AC Battery Charger

Option of Inverter:

  • EN1120S-X - Enerdrive 2000W Inverter with RCD & AC Transfer Switch
  • EN1226S-X - Enerdrive 2600W Inverter with RCD & AC Transfer Switch

Option of Monitor: 

  • EN55050 - Enerdrive ePRO+ Battery Monitor
  • SI-PICO-3 - Simarine Pico+ Display Panel Mount Black with SI-SC303 & SI-SCQ50

Here's how these components work together:

  • The 40A DC2DC charger takes charge of replenishing the lithium battery during travel or when solar panels are accessible, ensuring an efficient battery charging process.
  • The AC charger comes into play when you're linked to an AC power source, such as a campsite with electrical hookups or a marina with shore power. It provides a convenient method for recharging the battery when AC power becomes available.

The combination of both DC and AC charging options offers versatility in recharging your battery, catering to various scenarios. The DC charger is apt for charging on the move, while the AC charger proves valuable when you're stationary and connected to the grid.

This setup offers flexibility in recharging your battery, considering both your mobility and access to AC power sources. It's important to consult the manufacturer's recommendations and user manuals for each component to ensure proper installation and operation in your specific application.

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.

  • How many cells are in the Enerdrive 200Ah Btec Battery?

    There are 32 (8x 4) Prismatic Cells in the 200Ah Btech Battery.

  • What size generator should I use for charging a battery?

    The below generators are the minimum recommend sizes based on an AVR generator:

    ● 800VA 2KVA

    ● 1200VA 2.5KVA

    ● 1600VA 3KVA

    ● 3000VA 5KVA

    ● 5000VA 8KVA

    If your generator is smaller than the recommended size for your inverter/charger, you will definitely need to adjust the settings on the inverter/charger and reduce the AC input current limit, and/or a DC charge current limit to prevent overloading the generator. If you do want an inverter based generator get one that is at least 30% larger than required than an equivalent AVR based model to help prevent overloads.

  • Can these chargers take solar input?

    No, the battery charging component is an AC input, meaning only AC power (mains power) can charge through this unit.

  • How can I remotely monitor and control my devices?

    You need a GX device to get remote monitoring. We recommend the Cerbo GX and an RJ45 UTP cable to connect it to the inverter. You can hardwire an ethernet connection to the unit, or connect it to a Wifi signal.
