Low Voltage

  1. I've just installed a 12 volt system with a TrakMax 40BT controller, It continuously reads E3( low battery voltage) but shows the battery voltage at 11.9 volts, am I missing something? it is a 12 volt system.
    Thank you for any insights.

    Any thing lower then 12 volt is low voltage. A fully charged 12volt battery is 14.4 volts.
    TomT and Nekatlla like this.
  3. Lol I’m a newbie, went today and checked it again everything is fine! And yes the battery bank is 13.9-14 volts sorry but thank you!
