For example, the indicating circuit may be provided with two LED lamps R (Red LED) and Y (Yellow LED) on the key sheet, and the LED or the like is coupled to the control circuit U3 through the five-legged connectors CON1 and CON2. After the control circuit U3 acquires the current state of the rechargeable battery 721, it can be instructed by controlling the LED lamp.
[0177] In an embodiment of the present invention, the battery state detection circuit 724 is adapted to detect a charge current Charge AD and a discharge current Discharge AD of the rechargeable battery 721 and to input a detection result to a corresponding pin of the control circuit U3, The current state of the rechargeable battery 721 is determined by the control circuit U3 based on the detection result.
[0178] In the specific implementation, referring to
[0179] When the charge current Charge AD & gt; 0 of the rechargeable battery 721 is controlled by the control circuit U3, it is determined that the rechargeable battery 721 is in a charged state, when the discharge current Discharge AD<0 of the rechargeable battery 721, it is determined that the rechargeable battery 721 is in a discharge state.

[0182] Specifically, in the first detection sub-circuit U5, The RS-terminal of the first resistor R1 is coupled to the first terminal k of the sampling resistor Rcs, the RS+terminal of the second resistor R2 is coupled to the second terminal m of the sampling resistor Rcs. In the second detection sub-circuit 252, the RS+terminal of the first resistor R1 is coupled to the second terminal m of the sampling resistor Rcs, the RS-terminal of the second resistor R2 is coupled to the first terminal k of the sampling resistor Rcs.
[0183] The first detection sub-circuit U5 and the second detection sub-circuit U6 may amplify the voltage difference across the sampling resistor Rcs. When the rechargeable battery 721 is discharged, the PMOS transistor P1 of the first detection sub-circuit U5 is turned on, output discharge current Discharge AD=(V1*R1)/(Rcs*R3), where V1 is the voltage at the output terminal of the first detection sub-circuit 251. When the rechargeable battery 721 is charged, the PMOS transistor P1 of the second detection sub-circuit U6 is turned on, output Charge Current Charge Charge AD=(V2*R1)/(Rcs*R3), where V2 is the voltage of the output terminal out of the second detection sub-circuit 252.

[0213] Vision
[0214] We set out to create the brightest and most versatile, adventure ready LED light. A light that could keep up with unbridled creativity and imagination. A light that would enable amazing moments never before captured in low or no light conditions.
[0215] Our mission was to create a:
[0216] Best in class mobile light for photo and video professionals.
[0217] Best in class light for everyday tasks at home, at work, with a smart phone and for walking and biking
[0218] Best in class light for outdoor enthusiast and extreme athletes
[0219] A key design criteria was to make sure the light could go anywhere a GoPro Session 4 (and now 5) camera can goliterally!
[0220] Fit into the GoPro Session Frame and GoPro mounting system
[0221] Match or exceed waterproof and drop test specifications
[0222] Light beam angle complements camera lens' wide angle
[0223] Match battery life
[0224] Torch design goal was to go anywhere GoPro Camera can go AND fit into the GoPro and traditional camera mounting systems
