Battery Discharge Protection

Undervoltage cutback – or Battery Discharge Protection

This is now fitted as a standard feature to the Pro-100 / 160 / 360 models. These have adjustable warnings and cut-off levels which are useful for preventing damage to expensive lithium batteries.

The 4QD-200 / 300 had an analogue adjustment.

The DNO can be modified by fitting a zener diode to provide this feature.
