Hello everyone,
Please see attached circuit image for the following problem.
In order to prevent batteries to get hot, I have to either disconnect the USB cable or the T1 and T2 connection to PWM. USB cable is not connected to a power outlet.
Users can’t open the case to connect or disconnect the USB cable or T1 and T2. Therefore the circuit should work as-is without batteries get hot.
I use a 9v battery with USB to avoided charging PCB. Plus I can faster assembly the charging circuit. If you suggest changing the batteries, I would appreciate also give me a charging circuit.
Thank you very much for your help.
