A few months ago, I was contacted by Chris Dougherty at Trailer Life Magazine.  He invited Battle Born Batteries to do a project with Xantrex on Trailer Life Magazine’s in-house towable unit.  The project involved the installation of the new Xantrex XC2000 inverter charger and two of our Battle Born BBGC2 100ah lithium batteries. All our batteries are the only drop in replacement for a 6-volt lead acid battery in the market.



The new Xantrex Freedom XC family includes two inverter chargers:

  • XC2000 – 2000-watt inverter charger with 80-amp charger
  • XC1000 – 1000-watt inverter charger with 50-amp charger


The Trailer Life Magazine article, “Quest for Power” covers all the items needed to complete an upgrade like this.  We fully tested the Xantrex XC2000 here in-house without batteries.  This unit has been designed with all the features and flexibility that you need.  Some of the key features that we really liked are:



  • Fully programmable from the unit itself, no remote required.
  • Built in display on the unit
  • Easy DC and AC connections
  • Reverse Polarity protection
  • Converter and Inverter in one
  • Wide DC input range
  • Programmable AC Under-Voltage Shutdown
  • Smarter Power Factor Corrected Charging
  • Power Share


The XC2000 accommodates all the standard features you expect to find on a pure sine invert charger and many more.  We really enjoyed the fully programmable charging algorithm and the DC disconnect.

You might also be wondering about a few of these features.  To elaborate, let’s start with the most interesting one, it’s a converter and inverter all in one? That is correct. This unit is an inverter charger, but it’s a bit different than a standard inverter charger. The XC2000 can pick up a battery at 0 Vdc, which is uncommon amongst all other inverter chargers on the market.

Xantrex really hit the mark on the XC2000, in comparison to other inverter chargers, there’s a common problem among that causes inverter chargers to have a problem below 5-8 volts. The inverter chargers with this issue cannot see a battery, so they won’t charge the bank. However, the Xantrex XC2000 unit will start charging at any voltage, which means it’s great for lithium deep cycle batteries like ours.  If you run the batteries low the implemented BMS will shut the battery off.  Eventually, this will drop the voltage below 5-volts, while most inverter chargers will not charge batteries until a 12-volt source is applied.  This new Xantrex XC2000 works perfectly when accompanied by Battle Born Batteries.  Lastly, by having dead battery charging down to 0 Vdc, it really hits the unit home.

Next, you are probably wondering about the reverse polarity protection.  While lots of inverters have tried to incorporate this feature, the new XC2000 has it already built in.  Ultimately, we really wanted to see how it worked, so after conversing with our friends at Xantrex, we tested it.  Not only did it work, it worked better than we thought. The fuses did not blow until the 4th time we connected a battery backwards, which we were pleasantly surprised with.  Generally, a reverse polarity means a death sentence for most inverters, but once again Xantrex raised the bar. Here is a link to a video from Xantrex covering some of the other features within the unit.

Conclusively, we truly had a great time working on this project. We have provided a link to the full article on their site here. For more great articles from writers like Dougherty, please like this and subscribe  to Trailer Life Magazine today!

Alongside, we have provided all the settings on the XC2000 for the trailer life build. Here is the list of changes we made here at Battle Born Batteries:

1) Inverter Ignition Control (for a towable off is good, this is the default setting.)

2) LBCO Voltage ‘default 10.5’ –  11.5 is good here, to keep the BMS from shutting down.

3) LBCO Shutdown Delay Timer – Default 300 seconds.

4) LBCO Recovery Voltage – Default is 13.1, up to 13.4 is good too.

5) Power Save Time

6) Power Save (Load Sensing) Mode – Same as above.

7) Output Frequency default is good

8) Output Voltage default is good

9) Inverter Output Power Limit (Freedom XC 1000) Default is good for both of these.

10) Inverter Output Power Limit Timer

11) Transfer Mode – Default is good

12) Utility AC Under Voltage Level 90 volts is great especially when running a generator.  Leave this at default.

13) Inverter Shutdown Recovery – Default is manual, I feel like this should be switched to auto once you have everything installed and working.

14) Audible Alarm – Leave this on at Default

20) Battery Type – we will use custom

21) Battery Temperature – we will use custom

22) Custom Absorption Voltage 14.4

23) Custom Float Voltage 13.4

24) Charger Current (Freedom XC 2000) leave at default 100% if you are using more than 160 amps of lithium.

26) Charger Ignition Control – for towable this is off, its fine at default

27) Equalize Charging for Flooded Battery – Off is default, don’t use it for lithium

28) AC Input Breaker for Load Share

99) Reset all settings to their default values

NOTE: There is no 15-19 setting, as well as no 25 setting.

    Are there any settings to set how long the absorption stage last? I have 400aH and from what I understand, it is recommended to be at this stage for 2 hrs.

    • Dianne F | Nov 16, 2018 at 1:13 pm

      Hello Gideon,

      You are correct. We recommend thirty minutes per battery. If you have any further questions please feel free to call us at 855-292-2831 or call email us at [email protected]

    There doesn’t seem to be a setting on this XC2000 for Absorb time. Is that not an issue with the BB batteries?

    • Dianne F | Nov 19, 2018 at 9:55 am

      Hi James, by setting the absorption to 14.4 volts this device will work great! Some other devices have programmable absorb time functions. It’s okay that this device doesn’t. It works great paired with our batteries. Have a great week!

    Will the Xantrex HFS 2055 work well with BB Batteries?

    • Dianne F | Feb 7, 2019 at 8:15 am

      Hi Heather,

      Most of the Xantrex inverters that we come across here at Battle Born work very well with our batteries. With this particular unit, there is a “custom” mode which will allow you to set the bulk, absorb and float voltages. you will want 14.4v for bulk and absorption and 13.6 or lower for float. Make sure that there is no equalization and that temperature compensation is disabled(if its an option).

      Thank you,

    Thank you, Dianne!

    Now I am thinking about going with the Xantrex xc 2000. I have a 2018 Winnebago Minnie Plus 27bhss, with a WFCO 8955. Does that mean I wouldn’t be able to run the 80 amps that this device puts out? I have 2 100amp BB batteries coming soon. Would I have to change some cables? When you say “charger current, leave at 100%” do you mean leave it at 80%? Thank you and sorry, I’m new to all this.

  • Michael Brown | Apr 18, 2019 at 9:55 pm

    Good news: The latest versions of the XC2000 have much better 120v wire connectors. Very easy to use with no tools, & they appear to support large wire sizes such as #8 or #6.

  • Nate Goven | May 17, 2019 at 11:35 am

    Can you confirm having an absorption time that isn’t adjustable is optimum for my Battleborn? I am under the impression keeping this time to a set minimum is best, yet the Freedom XC has a default of 6 hours per the manual.

    • Dianne F | May 22, 2019 at 8:44 am

      Hi Nate,

      Having an absorption time of 20-30 minutes per battery in parallel is all that is needed to make sure that our batteries are completely charged and balanced. A longer absorption time will not damage or harm the batteries.

      In my small off-road camper
      I have just installed one 100AH BB batt
      The Victron MPPT 100/20
      And Victron BMV-712 Smart
      I have one 100w panel and plan to add one 150w panel
      Reading the manual for the BMV 712
      I see recommendations for setting charge efficiency to 99%
      Set Peukrts exponent to 1.05
      Is that your recommendation For your battery?
      Also, should I disconnect the battery when not in use for long periods of time
      The panels are always going and I drive it weekly which charges the battery
      I’d like to leave the fridge on
      Recommendations appreciated thank you so much!

      • Dianne F | Dec 11, 2019 at 2:44 pm

        Hello Fenton,

        For your BMV, Yes you will want to change the charge efficiency to 99% and the Peukert exponent to 1.05. In addition make sure that you change the battery capacity to 100AH(for one battery) and the Charged voltage to 14.3 to 14.4 volts.

        For storage, bring the battery to a full charge and disconnect the batteries from anything coming in or out, after 6 months your battery should still be around 75% full. The storage temperature range is -10 to 140F.

        Thank you,

    From what I’ve observed, the XC2000 absorbs until the charge current drops below the “exit current” (Xantrex term), or when 6 hours of absorption time has elapsed, whichever is shorter. 6 hours is the MAXIMUM absorption time. Unless the battery bank is huge, that will never happen. The exit current is the larger of 10% of the charge current, or 2 amps. In my case, with 2x BB10012’s, absorption only lasts a few minutes. My charge current is set at 60a (0.3C), and the exit current is therefore 6a.

    My theory is that by setting the charge current to 20a (0.1C) or less, the exit current drops to 2a, and the time in absorption will increase – perhaps topping off the battery a little more thoroughly. Since we cannot vary the absorption time or the exit current on this unit, perhaps we can manipulate it with the settings that we DO have control over. Is there any disadvantage to charging these batteries at a very low C rate? Will they top-balance better, if the absorption lasts more than a few minutes? Why isn’t absorption spelled with a B? 🙂 Comments?

      Hi Michael,

      Thanks for your comments and the information on this. There really isn’t any disadvantage to charging our batteries at a lower rate and the absorption time will vary when the charger has more of an “adaptive” method. This absorption method usually works well to top balance our batteries but if you want to extend the time in absorption, its best to get a charger with a “Fixed” absorption time that you can set to a specific value such as the Victron products.
      Yes you are correct, absorption is with a “P”!

      Thank you,

    Will the Xantrex Prowatt SW2000 work with Battleborn Batteries?

    • Jesse Asay | Mar 20, 2020 at 5:13 pm

      Hi Brian,

      The Prowatt is an inverter only and will work great with our batteries. Just remember that you will want to match every 1000 watts of inverter with one of our 100AH batteries.

      Thank you,
