GV650MG

Queclink GV650MG — LTE Cat M1/NB2 Heavy-Duty Waterproof Tracker with OPEN CAN and 4-Month Battery

The Queclink GV650MG is a rugged, heavy-duty LTE Cat M1/NB2 tracker specifically designed for demanding equipment, trailer and cold chain applications. Its IP67/IP69K dual-rated waterproof enclosure delivers outstanding protection against dust, high-pressure water jets and temporary immersion — making it the ideal tracking solution for construction machinery, agricultural equipment, tankers and refrigerated trailers operating in harsh outdoor environments.

Powered by a massive 5,800mAh Li-ion battery pack, the GV650MG can operate for up to 4 months without external power, ensuring continuous asset visibility even when equipment is disconnected or stored for extended periods. The device supports OPEN CAN architecture for extensive personalisation, alongside multiple pre-integrated interfaces for driver identification, temperature monitoring and engine control. Dual-band L1/L5 GNSS delivers enhanced positioning accuracy in challenging signal environments including urban canyons and beneath tree canopy.

As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the GV650MG directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

Frequently Asked Questions

How long does the GV650MG battery last without external power?

The GV650MG's 5,800mAh Li-ion 18650 battery pack provides up to 4 months of operation without external power, depending on the reporting interval. This makes it ideal for trailer and asset tracking applications where the device may be disconnected from vehicle power for extended periods.

What is OPEN CAN architecture on the GV650MG?

The GV650MG features dual CAN bus interfaces (CAN1 and CAN2) that support Queclink's OPEN CAN architecture — allowing telematics service providers to access and decode a wide range of proprietary CAN bus data from heavy commercial vehicles. This enables collection of engine RPM, fuel level, odometer, fault codes and many other parameters beyond standard OBD-II data.

Is the GV650MG suitable for cold chain monitoring?

Yes, the GV650MG is well-suited to cold chain applications. It connects to BLE temperature and humidity sensors wirelessly via BLE 5.2, and also supports RS232 connection to refrigeration controller units for direct reefer temperature monitoring and control data. Combined with the IP67/IP69K waterproof rating, it is designed for the demanding conditions of refrigerated transport.

What is the difference between IP67 and IP69K on the GV650MG?

IP67 certifies full dust protection and resistance to temporary immersion in up to 1 metre of water for 30 minutes. IP69K additionally certifies resistance to high-pressure, high-temperature water jets — the kind used in truck wash facilities and heavy equipment cleaning. The GV650MG holds both ratings, making it suitable for assets that are regularly power-washed.

Does the GV650MG support an external GNSS antenna?

Yes, the GV650MG supports an optional external GNSS antenna in addition to the internal one. This is particularly useful for installations on trailer walls, inside enclosed cargo bodies or in locations where the internal antenna may have a restricted sky view.
