This is normal and does not affect performance. Please fully charge before first use. **Q: Why is the SOC displayed by the APP inaccurate?** A: Possible causes include lack of full charge/discharge cycles, high-rate discharges, natural aging, or extreme temperatures. Solution: perform one full charge–discharge cycle to calibrate. **Q: Why can’t my phone find or connect to Bluetooth?** A: Please check: (1) Ensure Bluetooth and location services are enabled and the APP has permissions; (2) Keep the phone within 1–2 meters of the battery; (3) If using a Samsung device, try another brand to rule out compatibility issues. **Q: How do I confirm if the battery itself is working normally?** A: Disconnect the battery from all devices and use a multimeter to test its voltage. If the reading is normal, the battery is functional and the issue is likely with the Bluetooth connection or APP settings. ## Frequently Bought Together - ECO-WORTHY 12V 280AH LiFePO4 Lithium Battery with Bluetooth, Low Temp Protection, Built-in 200A BMS, 3584Wh Energy.
