  • EPL-200BT-12V-G2 - Enerdrive B-TEC 200Ah Lithium Battery
  • EN3DC40+ - Enerdrive 40A DC to DC Battery Charger
  • EN55050 - Enerdrive ePRO PLUS Battery Monitor

Optional Charger:

  • EN31240 - Enerdrive 40A AC Battery Charger
  • EN31260 - Enerdrive 60A AC Battery Charger

To effectively manage your power system with an Enerdrive B-TEC 200Ah battery, a 40A DC2DC charger, a 40A/60A AC charger and an ePro Plus Battery Monitor, it's important to know how these components interact in your energy setup.

  • B-TEC 200Ah Lithium Battery: This serves as the cornerstone of your energy storage system, with a 200 ampere-hour capacity. It is the source of electrical energy for powering your appliances and devices, regardless of whether your application is an RV, boat, or another off-grid setup.
  • 40A DC2DC Charger: The DC-to-DC charger plays a pivotal role in your setup. It diligently regulates and transforms incoming DC power from various sources, such as your vehicle's alternator or solar panels, ensuring it's efficiently channeled to recharge the battery. With a capability of delivering a maximum charging current of 40 amps when sourcing power from DC sources, it guarantees the optimal charging performance.
  • 40A/60A AC Charger: The AC charger is used for recharging 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 40/60 amps to recharge the battery.
  • ePRO Plus Battery Monitor: The ePRO Plus Battery Monitor is a critical component that keeps you informed about the state of your battery. It provides real-time data on your battery's voltage, current, state of charge, and more. This monitoring system enables you to keep a close eye on your battery's health, ensuring you have a clear understanding of its performance and capacity. With this information, you can make informed decisions about your energy usage and recharging strategy.

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
  • Do lithium batteries need to be ventilated? Any other install tips for my Enerdrive lithium battery?
    The batteries do not vent, so no need to be concerned about installing your Enerdrive Battery in a highly ventilated space.  
    It is recommended to keep them in a cool dry area to increase longevity. 
    Do not mount the battery on its side - it needs to be keep upright. Thanks.
  • What size battery charger do I need for my lead acid battery I have in my camper?

    A good battery charger rule of thumb for charging a lead acid battery, is using a charger with output current (amps) of 10-20% of the battery total stored capacity (Ah).

    So, for example if the battery is 12V 100Ah, the charger need to be minimum of 10A and maximum of 20A.  Often splitting the difference at 15% (so a 12V ~15A charger) is a good option. Happy charging!

  • Hi, just wondering if you are able to select which the charger will draw from first? Eg. Solar over alternator. If so will it still use the alternator if more is needed?

    Hi Isaac,

    There are provisions to manually override the charging source from alternator to solar.

    However Enerdrive state: If Manual Override Mode is used and left on there is a risk of flattening the start battery. The preferred method is to use the automatic override method by connecting the ignition source to the ignition terminal of the DC2DC+ charger.

  • HI, is the latest model that will charge up to 50amps?Cheers

    Hi Marc,

    Yes this is the latest model from Enerdrive.

    It does have the capabilities of charging up to 50A!

  • 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.

  • Can I use the dc2dc charger with a 600 watt wind turbine. I have a battery bank of 4 120 AH 12 volt batteries.

    Hi There,

    This charger is not suitable for use with wind turbines sorry.

  • I want to use a generator to run an Enerdrive Battery Charger like this - what is the recommended size generator?

    Hi Tom – the most popular size generator to run a battery charger like the Enerdrive ePower series is a 1000 Watt generator, such as the Yamaha EF1000iS. It is lightweight, fuel efficient and very quiet. 

    Note that the Enerdrive ePower 60Amp Charger model will draw a max 1050 Watts of power, in which case you might want to look at a 2000 Watt generator if you want to get the full power of of your 60Amp charger. Alternatively, the ePower charger series have a Current Control feature, which allows the user to adjust the current output - so for example you can dial back at 60Amp charger to still run off a 1000 Watt generator :)

    Many thanks.

  • 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.
