useful when troubleshooting battery issues. To access the
the left on the main app screen. You should see a screen like the one shown here.

send it to your support contact.
Module(s) Voltage data
Most Lithionics Battery systems are built as modular assemblies, with series/parallel connected
battery modules and an external NeverDie® BMS unit. In such a modular architecture,
troubleshooting comes down to checking voltages of individual modules and checking
continuity of all connections. A healthy and well-maintained battery would exhibit the same or
very similar voltages on all modules of the same configuration, so if you see one module's
voltage is significantly different from the other modules, it could indicate an imbalance in the
State of Charge between modules, which causes unexpected BMS events, since BMS protects
the individual cells in the difference modules.
You can also swipe left from the Battery Details screen to access Modules Details screen, where
all individual cell voltages and other parameters are listed for each module.
When contacting Lithionics Battery for support, please take a screenshot of the Modules Data
screen and send it to your support contact.
Collecting and analyzing battery data logs
The Lithionics Battery Monitor app has an automatic data logging function, which records
battery data into a log file whenever the app is connected to the BMS. While troubleshooting
battery issues it's recommended to have the app connected to the BMS before, during and after
the event(s) which are being analyzed. This allows Lithionics support team to plot the real time
data and observe changes in battery values while battery related events are taking place. Log
files are saved on the mobile device where the app is installed and can be accessed even after
the events are recorded. Log files are listed and sorted by date, where file name indicates the
battery serial number and date/time when the log was started. Log files can be emailed to
Lithionics support team directly from the mobile device, swipe left on the log file entry to access
Share icon, then select Email app. To learn more about collecting and sharing data logs, please

Each battery module has its own small red Status LED which can
be useful for battery troubleshooting. It provides heartbeat blink
patterns with 1 second intervals. The following table describes
the meaning of each blink pattern.
