- The relay needs to consume a lot of energy in the on-off moment, and the small battery will dead in the instant it is switched on, so BATTERY2 chooses a larger capacity battery with 9V voltage for power supply.
- The Bluetooth function requires a large operating voltage (>7V), which is greater than the operating voltage of power light.
- The power of the HEATER is relatively large, and two 3.7V 150mAh batteries will be exhausted in a few minutes.
