Battery and charging

The QL-200 uses a 24 V LiFePO4 pack. Normal consumption while executing missions is 15 to 22 % state of charge per hour. Robots dock automatically below 22 % and charge at about 60 % per hour up to 95 %.

Abnormal drain

Consumption above 30 % per hour, or more than 1.6 times the fleet median, is abnormal. Check first for mechanical resistance (see drive train troubleshooting); battery ageing produces a gradual increase over months, not a sudden step during a shift.
