TOPFLYtech KnightX 300 — 4G Cat-M1 Rechargeable Battery Asset Tracker
The TOPFLYtech KnightX 300 is a compact, rechargeable 4G LTE Cat-M1/NB2 battery-powered asset tracker designed for applications where permanent vehicle wiring is unnecessary or impractical. Its integrated 6400mAh lithium-ion battery, multi-constellation GNSS receiver, BLE 5.1 connectivity, panic button, internal temperature sensing, and optional external temperature probe make it suitable for tracking valuable assets, equipment, cargo, and temperature-sensitive goods. (TopFlyTech)
Because the KnightX 300 can simply be placed with the asset without a conventional hardwired installation, it is particularly useful for portable or temporary tracking applications. TOPFLYtech supports real-time reporting intervals as short as 3 seconds, while location records can be buffered when cellular coverage is unavailable. Movement-start and movement-stop alerts provide additional visibility into asset activity. (TopFlyTech)
The device combines cellular, GNSS, BLE, local sensing, and rechargeable battery power in an IP67-rated enclosure measuring 91.8 × 43.5 × 29.2 mm and weighing 165 g. TOPFLYtech lists FCC, IC and PTCRB certification along with approvals from AT&T, T-Mobile, U.S. Cellular and Verizon for North American deployments. (TopFlyTech)
Multi-Constellation GNSS Positioning
KnightX 300 incorporates an all-in-one GNSS receiver capable of simultaneously supporting GPS, GLONASS, BeiDou, Galileo and QZSS. TOPFLYtech specifies autonomous horizontal positioning accuracy of less than 1.5 meters CEP. (TopFlyTech)
With EPO assistance, manufacturer-specified time-to-first-fix performance is:
-
Cold start: <5 seconds with EPO; 28 seconds without
-
Warm start: <2 seconds with EPO; 25 seconds without
-
Hot start: <1 second
This multi-constellation architecture provides the tracker with access to multiple satellite systems rather than relying exclusively on GPS. (TopFlyTech)
4G LTE Cat-M1, NB2 and 2G Connectivity
The KnightX 300 supports LTE Cat-M1, LTE Cat-NB2, and GSM/EDGE cellular technologies across a broad selection of frequency bands. (TopFlyTech)
LTE Cat-M1 bands include:
B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B25/B26/B27/B28/B66/B85
LTE Cat-NB2 bands include:
B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B25/B28/B66/B71/B85
The unit also supports 850/900/1800/1900 MHz GSM/EDGE.
For communications with a telematics platform or application server, supported transmission protocols include TCP, UDP, MQTT and SMS. TOPFLYtech also specifies optional MD5/AES data security and encryption. (TopFlyTech)
Rechargeable 6400mAh Battery
A major feature of the KnightX 300 is its integrated 6400mAh / 3.7V rechargeable lithium-ion battery, allowing the tracker to operate independently of vehicle or asset power. (TopFlyTech)
TOPFLYtech publishes the following estimated battery-life examples based on two hours of active tracking per day:
| Reporting Interval | Published Battery Life |
|---|---|
| 10-minute reporting | 146 days |
| 5-minute reporting | 96 days |
| 1-minute reporting | 44 days |
Actual battery life will depend on reporting frequency, cellular conditions, GNSS acquisition, BLE usage, temperature and other operating conditions. The device can also generate a low-battery alarm when available battery power becomes low. (TopFlyTech)
Real-Time and Buffered Location Reporting
For applications requiring higher-frequency visibility, KnightX 300 can provide location updates as frequently as every 3 seconds. (TopFlyTech)
When the tracker moves outside cellular coverage, location points can be retained in its buffer rather than simply being lost. This capability is particularly valuable for mobile assets that routinely travel through areas with intermittent network service.
Movement Detection and Alerts
The KnightX 300 supports start-moving and stop-moving alerts, allowing a connected tracking platform to identify changes in asset activity. (TopFlyTech)
This functionality can be useful for monitoring equipment utilization, unauthorized movement, cargo handling and other situations where knowing when an asset begins or stops moving is important.
Panic Button
TOPFLYtech equips the KnightX 300 with a panic button, distinguishing it from many conventional unattended asset trackers. The feature expands the device's potential use cases where a person accompanying an asset may need to generate an immediate event or alert. TOPFLYtech specifically describes the KnightX 300 as a rechargeable battery tracker with a panic button. (TopFlyTech)
Temperature Monitoring
The KnightX 300 includes one internal temperature sensor and supports an optional external temperature probe. (TopFlyTech)
This provides additional flexibility for applications such as temperature-sensitive cargo and cold-chain monitoring where location alone does not provide sufficient operational information.
TOPFLYtech also lists compatible wireless temperature and humidity sensing accessories, expanding the environmental-monitoring possibilities through the device's BLE interface. (TopFlyTech)
BLE 5.1 Wireless Sensor Connectivity
Integrated Bluetooth Low Energy 5.1 allows KnightX 300 to communicate with compatible wireless sensors and accessories. (TopFlyTech)
TOPFLYtech lists accessories including temperature sensing devices, a key-fob/panic-button accessory and wireless relays. BLE therefore allows the KnightX 300 to function as more than a standalone location tracker when incorporated into a broader sensor deployment.
USB-C Interface and FOTA
A USB-C interface is provided for data communication. The tracker also supports FOTA (Firmware Over-the-Air), enabling compatible firmware updates to be delivered remotely instead of requiring physical access to every deployed tracker. (TopFlyTech)
Network, GNSS and Wi-Fi antennas are internally mounted, helping maintain the device's compact self-contained design.

Compact IP67 Enclosure
TOPFLYtech specifies an IP67 ingress-protection rating for the KnightX 300. The enclosure measures:
91.8 × 43.5 × 29.2 mm
3.61 × 1.71 × 1.14 inches
Device weight is approximately:
165 g / 5.85 oz
Published operating temperature is:
-20°C to +80°C (-4°F to +176°F). (TopFlyTech)
One inconsistency is worth noting for your DCS catalog: TOPFLYtech's current page labels the unit IP67 waterproof, but immediately states “Not for outdoor uses.” (TopFlyTech) Because those statements conflict, I would not advertise the KnightX 300 as an outdoor tracker without clarification from TOPFLYtech. Describing the enclosure simply as IP67-rated stays faithful to the published specification.
Flexible Installation and Accessories
Unlike a conventional hardwired vehicle tracker, the KnightX 300 does not require permanent vehicle wiring. TOPFLYtech states that it can simply be placed with the property being monitored without installation. (TopFlyTech)

-
Installation bracket
-
Mounting magnet
-
External temperature probe
