NOTE 1 :
Qualification is a hand shaking
procedure that allows a charger
to wake up an auto-on equiped
AES battery. Qualification is an
optional feature and not
required for standard charging.
CAUTION :
Extra considerations must be
given to depths of discharge,
operating voltages and currents
when designing systems for use
at maximum operating
temperatures.
CAUTION:
Direct connection to DC motors without proper safety protection, motor controllers, and external motor voltage clamping
systems (such as high power anti-parallel diodes or braking resistor systems) may result in damage to the internal pack
protection system which may result in unsafe situations. Please consult Discover technical support before directly
connecting any motor loads.
