I have a 24kwh battery built from a Nissan leaf. I have added a Batrium BMS system. My battery will not discharge beyond 65%. The settings in the ess are set to 20% in the discharge setting.

Anyone help. It's rather frustrating.i have been over and over the settings

Next thing to check is the sustain voltages set in the ESS assistant.

Try disconnecting the AC input and see if it discharges further then.

  1. I have had 2 notifications of low battery on the victron software both have been sent at around 50v. I am wondering if the batrium BMS was shutting off the battery would the victron unit send these alarms. Or are alarms only triggered when the victron unit says the battery is low
