Hello,
I am trying to build a circuit that allows charging a battery and at the same time run the circuit that I have.
I am thinking of using something similar to this for charging:
https://www.amazon.com/Anmbest-Char...2ed231&pd_rd_wg=D6YnD&pd_rd_i=B07KSPX859&th=1

but will I be able to have the outside power source connected to the P+ and P- and run the circuit as well?

 

Yes, providing the power supply is capable of supplying enough current to run both the charger and the circuit.

 

Will I need to put any extra components for protection?

 

Assuming the charger and the circuit need the same supply voltage, no.

 

thank you very much
