SC1 A battery is
supplying too much
current for too long.
This can either be
because of too much
power draw or a
battery cell
imbalance.
SC1 A battery voltage
was measured to be
lower than the
allowed threshold
but is still
recoverable.
SC1 A battery voltage
was measured to be
higher than the
allowed threshold.
SC2 The motor bus
voltage is lower than
the low voltage
threshold.
SC2 The motor bus
voltage exceeds the
high voltage
threshold.
