Common starting points¶
- Which battery chemistry for winter operation? The Battery Guide compares Li-Ion, LiFePO4, LTO and Na-Ion including cold behaviour and charge inhibition below 0 °C.
- Why does the app show an unexpected SOC? See Telemetry and the SOC→Li-Ion mapping section in the Overview.
- Red LED blinking, battery not charging. See the FAQ and the register verification section in the Overview.
- Which antenna and TX power are permitted? The regulatory limits are listed at the end of the Overview.
