Using Your Battery Backup Power Supply Using the battery backup circuit that I designed, you can plug your power supply into a female DC power connector. This is connected to the battery backup circuit.
I want to share a project about building a battery backup supply for small electronics. With this backup supply, you can never run out of power. There are a lot of electronics that need to be reliably on all the time. Alarm clocks are a good example of this.
When powering it on for the first time, use a power supply if you have one. Limit the current to 3A. This will keep everything from blowing up if something was connected wrong. Once everything is working using the power supply, you can use the battery. I would highly recommend adding a switch in-between your battery and the circuit.
Using Autodesk Circuits and a lead-acid battery, you can create a circuit that will act as a variable power supply, outputting a range of voltages from 5V to 20V. After creating the power supply you could drive motors using variable voltage, power microcontrollers, logic circuits, LED strings, analog circuits, and much more.
Once everything is working using the power supply, you can use the battery. I would highly recommend adding a switch in-between your battery and the circuit. It makes it easier to turn the circuit on and off, as well as making it safer. Once you get the circuit working with the battery, you are ready to power your electronic projects!
Next, a rechargeable battery is connected using a resistor and another diode. The resistor allows the battery to be slowly charged from the power supply, and the diode provides a low resistance path between the battery and the circuit so that it can power the circuit if the voltage of the power supply ever drops too low.
