Hi - forgive me I'm a mechnical guy with limited electrical knowledge.: )
I noticed cell phone batteries have small circuit boards at the end of the
pack. What is the purpose of the board?
I am being tasked with a project using arrays of larger lithium cells - I
think there are 12 per pack. Each array comes with a circuit board at the
end as well. I noticed on the circuit board there looks to be a small
buzzer or something? Am I correct in seeing that?
If I wish to disassemble the packs to make larger arrays - could I have a
circuit board built to handle the larger array? Or is it more advantageous
to have a bunch of smaller arrays/packs than one large one?
Lastly, are battery packs assembled in series or parrallel and what is the
thining behind one over the other?
Any help appreciated -
That question may be out of the realm of the modelers here but have
look here. This site is a wealth of information.
