Logic Battery
An optional logic battery supply is supported. Under heavy loads the main power can suffer voltage drops, causing potential logic
brown outs which may result in uncontrolled behavior. A separate power source for the motor controllers logic circuits, can remedy
potential problems from main power voltage drops. The logic battery maximum input voltage is 12VDC with a minimum input voltage
of 6VDC. The 5V regulated user output is supplied by the secondairy logic battery if supplied. The mAh of the logic battery should be
determined based on the load of attached devices powered by the regulated 5V user output.
