Mobile Power

Hi

Im looking for a mobile power solution for my nano + 3,5" nextion display.

I thought on a 6-7.2V akku pack with a plate for charging the akku and powering the modules with a voltage watchdog. While akkus are no issue, I have no idea about the plate. Has anyone experience with something like that? Any suggestions?

I assume that you ran your text through google translator.
Where you have AKKU I believe you mean BATTERY.

However, I am not sure what you mean by PLATE.

ehhmm yes by plate I mean board. and by akku I mean a chargeable battery.

So you are looking a charging module for a 6 cell 7.2V NiCad battery pack?

Yes and output voltage watchdog to make sure that the voltage stays above 5V

Why not just buy one of those common, cheap USB "power banks", like they sell for charging cellphones, and power through the USB port?

I wanted to build it myself...

Imo, save your time for the parts of your project that you cant buy off the shelf.

NiCad batteries are heavy and crappy, they fail if you dont fully discharge them every time, etc - and you can get these nice LiPo based modules for less than you could build it for, and its assembled and ready to go, so you can focus on the original parts of your project.

A self-defeating insistence in making every part yourself is called not-invented-here syndrome. Very common in maker types. Its why I cant do any project without making at least one custom pcb and why I still dont have a good light on my desk (I’ve got a pile of parts for the coolest desk light ever though!)
