Charging Circuit and Voltage Regulator for my robot

10 Duracell AA batteries are not rechargeable. Look at Li Po which are and can typical handle 3.7V or multiples of that depending on the number of cells.

It does say on the package in the amazon link that they are rechargeable. Or am I missing something?0.o

Thanks for your reply!:)

I think I have figured it out what you meant!

So if I use 4 Li-Ion batteries and 2 switching regulators to get the voltage down to 12V and 9V respectively I am still not sure how to charge those batteries without having to turn my Circuit of.

Thank you in advance!:)

Hi sesam

please consider that the Kinect device only draw 12W! Then there are motors, control board, etc

So I don't think the battery you selected are a good choice (they will drawn in a few seconds or less!)

If powered at 12 V, the Kinect draws 1 A of current. If you want you robot to run for, let's say, one hour, you battery should have a capacity of 1000 mAh

there NIMH Rechargeable (1.2V per cell) I have a load myself

you need a charger like this

from IC Station in this case but im sure you can find others

4S Li-ion Lithium Battery 18650 Charger Protection Board 14.4/14.8/16.8V 30A - Charger Module - Arduino, 3D Printing, Ro…

Oh, I did not know that it draws that much current! Thank you for this information!:)

So if I am not mistaken I will be able to let my batteries stay in the circuit while charging? That's awesome that there is such an easy solution since I read that it can be problematic to charge Li-Ion batteries which are connected in series!

Thank you very much!:)

But will it also automatically provide current to my raspberyy pi or do I have to separately connect it to my power source? And if not will I also have to disconnect the batteries from RPI with a relais or something?

Sorry for all the questions! I am just not really experienced with all that stuff and I don't want to screw it up!;P

Thank you in advance!

Another question that I have is whether is still need a constant current supply with this protection board or not?

Thank you in advance, Daniel!:)

this has balancing and all that cool stuff so it takes care of it

As far as I can tell you just give it volts, it takes care of all the constant voltage and current stuff for you
