Hi Everyone
Bringing my SimpBMS configuration on line and having a couple of problems.
My target environment is a bus conversion motor home with:
1. Victron Color control head
2. Victron Solar charge controllers
3. Singineer Inverter/Charger 6KW Tesla model APC6024DT
4. Two Tesla Model S modules connected in parallel.
5. SimpBMS for Tesla
My SimpBMSconfiguration:
1. SimpBMS 2.3 board
2. NEXTION display
3.LEM CURRENT Sensor CAB300-C/SP2 (Read documentation, VCC is connected to 12V for this sensor).
4.OMRON CONTACTORG9EA-3-CA-M2 (not using at the moment.)
All the above SimpBMS items were purchased directly from secondlife-evbatteries
My current status:
1.NEXTION display works well
2. Connected a terminal emulator to Teensy 3.2 compute module and see output
3. It is reporting that voltage as 45.6 as if the modules are in series.

4. I entered the setup menu and then debug and set the ESS mode to 1
5. I went back to the setup menu and selected "c" for current sensor calibration
6. I configured the sensor type and for LEM CAB series
Current Sensor Calibration Menu
c - To calibrate sensor offset
s - Current Sensor Type : Canbus Current Sensor
1 - invert current :0
2 - Pure Voltage based SOC :0
3 - Current Multiplication :1
7 -Can Current Sensor : LEM CAB series
q - Go back to menu
Calibrating Current Offset ::::: ....................5 current offset 1 calibrated
Calibrating Current Offset ::::: ....................5 current offset 2 calibrated
7. I then went to the Battery Settings Menu with the "b" letter command
Battery Settings Menu
r - Reset AH counter
f - Reset to Coded Settings
q - Go back to menu
1 - Cell Over Voltage Setpoint: 4200mV
2 - Cell Under Voltage Setpoint: 3000mV
3 - Over Temperature Setpoint: 65.00C
4 - Under Temperature Setpoint: -10.00C
5 - Cell Balance Voltage Setpoint: 3900mV
6 - Balance Voltage Hystersis: 40mV
7 - Ah Battery Capacity: 100Ah
8 - Pack Max Discharge: 30.00A
9 - Cell Discharge Voltage Limit Setpoint: 3200mV
0 - Slave strings in parallel: 1
a - Cells in Series per String: 12
b - setpoint 1: 3100mV
c - SOC setpoint 1:10%
d - setpoint 2: 4100mV
e - SOC setpoint 2: 90%
g - Storage Setpoint: 3800mV
h - Discharge Current Taper Offset: 300mV
j - Discharge Current Temperature Derate : 40.00C
I then attempted to use the command characters "0" or "a" to try and alter the values to setup for modules in paralleland got no response to the requests.
So at this point I have the following:
1. Reported pack voltage is incorrect
2. Charge or Discharge current is not being shown on the NEXTION display.
Thanks
