Which protection circuit module and which charger?

Hi, (I'm french, so i'm sorry for my english )
Actually doing a gamecube portable, I'm thinking of including some batteries that I got from a laptop that doesn't work anymore.
The battery is made of 6 of these cells (http://www.amazon.fr/Samsung-Li-Ion-bat ... B005D77MG0) and I wanted to put them in series and in parallel to get a battery a 14.8V batery pack and 4400mAh (or 6600 if I have enough space to put 6 of them) and I've read that I need to protect them with a protection circuit but when I search for one I only find circuits that allow me to put 4 cells to it. So I don't know where to find one that can get 5 or 6 cell and I really don't know how to wire the cells to the protection circuit. Also I wanted to know which charger should I use for charging the battery pack when it'll be done. So, if someone could help me with that that will be very great, thank you guys

Otherwise, if it's not possible to do it with these cells, I found this battery which seems to be nice and I wanted to know if anyone has tested it (http://fr.aliexpress.com/item/12-v-lith ... 89291.html) . But I think that it's really cheap compared the capacity of the battery and I'm quite suspicious, but I don't know much about batteries because it's the first i'm doing a portable.

Actually, wire them to get 11.1v at 4400mah, 3 packs of 2 cells(wired in parallel) that will be wired in series, with this protection:

with this charger:

Wire the cells this way:

If I could give you an advice, don't use used cells, and I would use flat ones if I were you, because round one usually takes more space and are almost impossible to solder to(plus, it's really dangerous to heat them with an iron)


You can also PM me if you want, I speak french also.

Ok thank for the advice
But will it be okay if I only give 11.1V to the gamecube? I'm using the original regulator and my screen runs on 12V.
Yes I know but these ones are a temporary solution until I get enough money to get some better batteries. And the cells have pads on them so I won't heat them with the iron.

Thanks but I prefer to speak here, because some guys might be in the same problem and like that they will have help too

Yeah, you should not have any problem using 11.1v, the screen probably works from 7-12v, not a problem either.
