Maintenance

The Senquip QUAD has been designed to require a minimum of maintenance. The only serviceable item is the internal LiPo backup battery.

Replacing the LiPo Battery

Battery caution wording

It is expected that the LiPo battery will have an in service life of 5 years. Factors that will reduce the life are:

  • Exposure to temperatures above 55°C or below -10°C.

  • Unusually high number of charge / discharge cycles.

  • Being left in a discharged state for an extended period of time.

Replacement of the LiPo battery should only be performed by suitability trained service personnel. Only LiPo batteries supplied by Senquip should be used. Senquip LiPo batteries contain temperature sensing and protection circuitry to ensure safe operation of the Senquip QUAD.

Note

Use of 3rd party batteries may cause damage to the unit and will void the warranty.

The LiPo battery is located under the user access panel inside the Senquip QUAD. To replace the LiPo battery, the following steps need to be completed:

  • Un-fasten the 4 hex-head screws securing the cover using a 4mm hex bit. The screws are captive and will not fall out when loose. Do not attempt to remove the screws from the lid.

  • When the lid is opened, an internal light detector will recognise the increase in brightness and will enable the LEDs and configuration switches.
