Firmware code suggests SpaceX developing battery-integrated Starlink Mini
University researcher Jinwei Zhao identifies code strings indicating a move toward untethered portability for the satellite internet dish, targeting users such as vanlifers and emergency responders.
Code embedded within a recent Starlink firmware update suggests that SpaceX is developing a version of the Starlink Mini satellite internet dish featuring an integrated battery. The discovery, identified by university researcher Jinwei Zhao and reported by PCMag, points to a significant shift in the device’s power architecture, moving beyond the current requirement for tethered connections to external power sources.
The firmware contains specific references to a "DishBatteryStats" message, a code string designed to return detailed battery fields, including the current state of charge. This native ability to monitor battery levels implies the presence of an internal power source, as the software would not require such granular data if the device were solely reliant on third-party power banks.
Further analysis of the code reveals support for three distinct power states. This indicates the hardware is being engineered to operate via direct USB-C input, its internal battery, or both simultaneously. Such pass-through charging functionality is likely intended to preserve battery health by mitigating the wear associated with excessive charge cycles, a common issue with portable electronics.
Currently, the standard Starlink Mini must be connected to an AC wall outlet or an external portable battery to access the constellation of over 10,000 satellites in low Earth orbit. While third-party solutions like the PeakDo LinkPower series exist, they have been criticised for cumbersome software and higher costs relative to standard external power banks. An integrated battery model would presumably offer a more seamless experience within the Starlink app and remain covered by the manufacturer’s warranty.
The potential product is expected to feature an airline-friendly battery capacity of approximately 99Wh, which could provide over five hours of runtime based on testing assumptions. This development would significantly enhance untethered portability, benefiting specific user groups such as vanlifers and emergency responders who require reliable, low-latency internet access in remote locations. However, these findings remain inferred from firmware code and have not been confirmed by an official product announcement from SpaceX.
