Will this charging circuit work with these batteries

[coppertj]

Hey, i'm wondering if these lithium polymer batteries ( http://www.batteryspace.com/polymer-li- ... d-dgr.aspx ) in a x3 series will work with this charging circuit ( https://www.sparkfun.com/products/12711 ).

Thanks.

You want to put 3 in series for 11.1v? If you want to do that, it wouldn't work, because that is for one battery. But if you're putting them in parallel it should work.

Would there be any possible way for a different charger circuit to work with 3 in a series. I'm trying to make the voltage close to 11.1v for a portable gamecube.

Most people would use these: http://www.batteryspace.com/pcbfor108v111vpack.aspx

You'd need a smart charger to go with it too:

That's the only thing you can charge it with.

So, for example, I could use this with the the 3 batteries:

and this to charge them all

Also, is their a way to charge it using these without having to open the portable to get the batteries? Something like a charge port that can be soldered on the PCB that will fit the smart charger.

Yes. The smart charger is a standard DC plug. You should be able to use a DC jack from any old electronics - the positive goes to P+ and the negative goes to P- on the charging circuit.

Alright! Thanks so much! Only other question I have is, how do you connect the batteries to the gamecube. Is it connected from the protection circuit?

It's tbe same P+ and P- pads. They are for charging as well as outputting voltage, which means you can't do both as the same time.
