The monitoring module can do battery test, and record 10 sets of test data
(accessible only through the host). The battery test has to be started
manually, then monitoring module will control the rectifier output voltage,
make it lower than the battery voltage, and the battery discharge will begin.
Monitoring module will stop the test if the battery voltage reaches the
“Battery test voltage”, or the discharge time reaches “Battery test time”, or
the battery capacity reaches “Test End Cap”. Afterwards, it will restore the
rectifier output voltage to the normal FC voltage, begin the battery charge
and switch the system to battery auto-management. Meanwhile the test
start time/voltage and end time/voltage and battery remaining capacity will
be recorded. The records can be queried through the host.
During the battery test, if abnormalities occur, the monitoring module will
stop the battery test automatically

When the parameter “Scheduled Test” is set to “Y”, the monitoring module
will test the battery according to the 4 sets of test time. You can set at most
12 sets of test time through the host

If the battery have not discharged within the “ShortTest Cycle”, the
monitoring module will start a short test, whose operation time is set by the
parameter “ShortTest Duration”. By the end of the test, if the difference in
the discharge currents of batteries is bigger than the “Alarm Current”, the
battery discharge imbalance alarm will be raised. This alarm will
automatically end after 5min of delay. Also you can end it by confirming it

The stable test is conducted with constant battery current, whose value is
set through the parameter “StableTest Current”. If the parameter
“StableTest Enable” is set to “Y”, and the test will be started once the
battery satisfies the test condition
