The LK900A, 900B & 900C 4G GPS trackers manufactured by LK-GPS is a professional grade, waterproof, magnetic asset and vehicle locator. Unlike the bicycle-tailored LK110, the LK900 series features a heavy-duty industrial magnet designed for instant "slap-on" mounting to vehicle chassis, shipping containers, or heavy machinery.
The LK900A represents the baseline battery capacity variant within the LK900 fleet tracking tier, which also includes the higher-capacity LK900B and LK900C iterations. The LK900A 5000mA battery lasts 10-25 days, LK900B 10000mA battery lasts 30-45 days and LK900C 20000mA battery lasts 85-110 days.
Core Technical Specifications
- Network Connectivity: Dual-mode 4G LTE (Cat 1) with 2G fallback ensures reliable cellular communication across changing network environments.
- Positioning System: Employs a triple-satellite constellation (GPS, GLONASS, and BeiDou) combined with LBS (Location Based Services) for high-accuracy tracking.
- Power Source: Built in rechargeable Lithium Polymer battery.
- Waterproofing: IP66 rated waterproof housing to withstand all weathers in exposed areas under vehicles and outdoors.
Key Security & Telemetry Features
- Comprehensive Instant Alerts:
- Geo-Fencing: Sends push notifications if the vehicle enters or exits a predefined geographic boundary.
- Vibration & Motion Sensors: Triggers an alarm if the stationary vehicle is bumped, towed, or tampered with.
- Overspeed Warning: Alerts fleet managers or owners if a set speed threshold is crossed.
- Tracking Platforms: Fully compatible with the official LKGPS2 app (iOS and Android), web portals, and popular third-party telemetry servers like Plaspy and Traccar. It can also be pinged directly via SMS to return standard Google Maps coordinates.
📡 Connectivity & Regional Network Versions
The modern global iteration relies heavily on 4G LTE-FDD/TDD protocols but retains backwards fallback compatibility.
