I want, using 5v from an USB, charge a 4.2v 18650 battery (wired to an TP4056)
I then boost the 4.2v to 5v to feed it to an arduino and to 1 or 2 servo motors. (I’ve drawn a schematic for better understanding).
I want the battery to get charged while I’m working on my code and than, once finished, have a portable power supply for what I’m currently doing.
I would like to have your opinion regarding this:
- Can I do something like this ? Or does it create some sort of strange loop ?
- Is there a better/safer/ mor efficient way of doing it ? Could be adding some parts or using better componants or doing it completely differently.
- Is there a componant that combines TP4056 + Boost converter ?
Any idea or suggestion is truly appreciated.
