How To Configure Victron BMV-700 with Bluetooth Dongle

  |   Battery Monitor, Uncategorized   |   20 Comments

 

The Victron BMV is an extremely versatile unit that allows its user to monitor virtually every aspect of their battery bank. In order to help take advantage of its enormous benefits, we created a walk through video on how to set the Victron BMV up with Battle Born Batteries.

    Here’s a quick reference so you don’t need to keep replaying the video like I did. There are only 4 changes from default (01, 02, 05 and 06) marked with a *:

    01 Battery Capacity — 99AH *
    02 Charged Voltage — 14.4v *
    03 Tail Current — 4.0%
    04 Charged Detection — 03
    05 Puekert Exponent — 1.05 *
    06 Charge Efficiency Factor — 99% *
    07 Current Threshold — 0.10A
    08 Time to Go Averaging Period — 03
    09 Zero Current Calibration — ZERO

    What are your recommended Alarm settings on the BMV-700 using LiFePO4 batteries?

  • Pete DeGraff | Nov 11, 2017 at 11:06 am

    Awesome! Thanks so much for making setup that much easier! So foolish question I’m sure, but with a two Battleborn 12volt system, set at 198ah per the video (99ah recommended on single battery) are there any other changes I should make? Thanks again.

      Hello Pete,
      If you have followed all of the steps in the video you should be good to go =)

  • Randy Eggers | Dec 14, 2017 at 6:34 am

    Do you have any graphs showing more details on voltage vs. amp/time draw on your 12 volt lithium battery under say a 2 or 5 amp draw over 12 hour period

    • Will Olney | Dec 14, 2017 at 8:21 am

      Hell Randy,
      Yes we do have these graphs send us an e-mail and we will get it sent over

    Ok so I have a system with the BMV-702, Victron 3000w/12v inverter and two Smart Solar charge controllers. I also have 5 of your batteries wired in parallel. I have noticed that my system is only charging to an SOC of .5% less than the day before. All of my equipment is set to the parameters listed here. Do you guys having any thoughts on what may be going on or what adjustments may need to be made?

    • Denis Phares | Jun 2, 2018 at 4:49 pm

      Johnathan,
      Try reducing your end charging current from 4% (as suggested in the video) to 1%. This will allow the batteries be topped off in the absorption stage a little bit more. This will also allow extra time for balancing. If the charge current is high, than 4% of the charge current may be too high for the final top off.

      Also, make sure that you don’t have any connections on the battery side of the Victron shunt, except for the negative terminal of the battery bank. That could create of a path for current to flow that is not being detected by the monitor and yield inaccurate SOC.

    Hi BB,

    I bought 3 100AH 12V last fall. Wired in parallel. . I configured it with a victron BMV 702 and a victron blue solar 100/30. Set up per your instruction videos. Very helpful btw. All is well no issues.

    A a week ago, I upgraded to a victron BMV 712 and a victron smart solar 100/30 and I’m curious how to ensure that I get the state of charge synced property. What advice can you offer me?

    Thanks.

      Sam,
      thanks for reaching out I am glad your system is working as planned. Best thing to do after programming it is to let it run for a couple of days, it should settle in properly. If that doesn’t work let us know we can help you via phone.

    I have a system with three, 24v 50ah batteries. Can you help me with the BVM-712 settings for this battery bank? I’m unclear if Battery Capacity refers to the individual batteries used or to the bank and if it is available capacity for use.

    • Dianne F | Oct 12, 2018 at 12:10 pm

      Hi Bill,
      The Capacity reading refers to the batteries as a whole. You will set your settings to 150AH because they are in a 24V system.

      Battery Capacity: 300Ah
      Charged Voltage: 28.8V
      Tail Current: 4.00A
      Charged Detection time: 3m
      Peukert: 1.05
      Charge Efficiency: 99%
      Current Threshold: .10A
      Time-to-go: 3m

      If you have any other questions Bill, please do not hesitate to give us a call or email us at [email protected]

    I have a system with 8, 12v 240ah batteries. Can you help me with the BVM-702 settings for this battery bank?. My system with the BMV-702 includes a Victron MultiPlus 48/5000/70-100 Inv/chrg.

    • Dianne F | Nov 7, 2018 at 8:54 am

      Joseph, what type of batteries do you have? Just so I can help you further.

  • Bob Sweeney | Nov 12, 2018 at 7:20 pm

    I have 3 Battleborn 100Ahr batteries connected in parallel in an RV for a 12v system. I use the BMV712 shunt on the negative battery posting. I also have 400W of solar via Victron 100-50 solar controller and Victron 2K inverter/charger. These components are all hooked into a Victron Venus hub reporting to the Victron VRM. There is no AC shore power connected to the RV, it is nighttime so no solar input. This is a new setup with individual components setup per instructions on this website. It has been running 2 days/nights and I am seeing the SOC more or less constant at 100% through the entire night. The battery voltage is 13.16v with a constant 2.80 amps current draw so I would normally suspect the SOC should be reading around 50%. I would expect to see the SOC slowly drop overnight and then start rising in the morning as the solar starts contributing. Any help is appreciated.

    • Dianne F | Nov 19, 2018 at 11:59 am

      Hello Bob,

      When you are seeing a 13.16 voltage that is right around 50% of your battery remaining. If you are starting the night after the solar charges during the day at anywhere between 13.6 and 14.4 then seeing 13.1 by morning time, that sounds about right. Is this the case?

  • Bill RICHCREEK | Mar 25, 2019 at 8:47 pm

    Battery Capacity — 99AH that’s if you are running only 1 battle Born 100 amp hour battery correct? So if I’m running 2 battle Born 100 amp hour batteries this should be set at 198?

    • Dianne F | Apr 10, 2019 at 5:01 pm

      Hi Bill,

      The amperage capacity should be set to what ever the total AH is of your entire battery bank. This will allow the correct calculations for the BMV and for 2 of our batteries you will want to set it for 200AH.
      The 99AH was an old measurement from previous batteries.

      Thanks,

  • LeRoi Keiller | Aug 20, 2019 at 10:14 am

    1) When we tap “synchronize SOC to 100%” do we do that when the battery monitor says the voltage is 14.4?

    2) Would specifying the resting charged voltage of 13.6 be incorrect for SOC (since the video says to enter 14.4)?

    3) There is lots of chatter about charging only to 90% to improve the longevity of the battery. Is this true?

    Regards,
    Leroi

    • Dianne F | Sep 11, 2019 at 2:01 pm

      Hello LeRoi,

      We typically recommend letting the BMV synchronize to 100% automatically instead of doing it manually if at all possible. This will insure accurate reading s if the synchronization is done prematurely. If for some reason you are getting to the 14.4 volts and it is not syncing to 100% then you could try this manually.

      For # 2 you will want the charged voltage set at the higher 14.4 volts. if a charger gets to 13.6 it does not mean the battery is full and there is no “full resting voltage” setting for the bmv.

      #3 Our batteries were designed to use all of the power without having to worry about only charging or discharging to a certain level. We recommend bringing our batteries to a 100% state of charge regularly and this will yield you at least 3-5000 cycles, probably many many more.

      Thanks,
