The BMS Summary page shows the average, minimum
and maximum cell voltages, and the temperature
sensor, plus a bar graph overview of all cells across
the bottom.
If no current sensor is present, this will be the default
page, and Pack Voltage will be shown instead of
Average Voltage.

The BMS Details page shows all individual cell
voltages, plus a bar graph below. Dotted lines on the
graph show HV and LV thresholds plus hysteresis.
Graph bars will be green when a cell is in range, blue
for under-voltage, red for over-voltage, and orange if a
cell is currently being shunt balanced.
Warning:
Overcurrent shutdown
If the BMS detects an error, this warning page
will be displayed. In most cases, the error can be
acknowledged/reset by tapping the screen.

Exit Options
You can bring up the options menu by touching and
holding for 1 second. From here you can do a manual
reset of the State of Charge (back to 100%), enter the
Setup mode, switch the display off, or command the
BMS16 to turn off.

If you choose Enter Setup, the Monitor can be used to
modify settings for the BMS16. The top row selects the
parameter, and the bottom row adjusts the value, in
both cases by touching the left or right arrows on each
side. Once finished, touch Exit Setup and the new
parameters will be transmitted to the BMS16.
List of Settings
The following table describes the parameters available in the Settings page.
Name
Range
Description
Pack capacity
5-1200Ah
The rated capacity of your traction battery pack,
in Amp-Hours.
SoC warning
0-100%
The BMS16 can raise a warning when the
battery’s State of Charge reaches a predetermined
minimum level. (Use 0% to disable.)
Full voltage
1-70V
The BMS uses a “full voltage” threshold
(combined with low charge current) to detect
charge completion and automatically re-
synchronize the SoC to 100% when pack
voltage exceeds this value. Typically set value to
just below your peak charge voltage.
Warn current
0-1200A
The BMS16 will provide a warning if the current
in or out of the battery exceeds this threshold.
Set to 1210A to disable (will display as “off”).
Trip current
0-1200A
The BMS16 will automatically shut down the
battery pack if current exceeds this threshold
(for over 1 second continuously). Note: This
should not replace a physical fuse, but can be
used as a “first line of defence”.
This is considered a serious error which will
require the device to be power cycled to reset.
Num cells
8-16
The number of cells the BMS should expect to
see in the battery pack. Warning: If this is set
incorrectly, some cells may not be monitored.
