Battery question...

[XFactor]

I was looking around this website and found this battery:
http://www.batteryspace.com/index.asp?P ... rodID=2333

This is different from the other battery in that it has 5000mAH instead of 3000mAH (meaning by what has been conveyed to me by timmeh that it will give me more capacity {gameplay time}, not voltage). It also comes with a PCB chip that will regulate the charge so it will not explode like normal lithium polymers.

The reason for my interest in this battery is that I want to keep the system as compact as possible while allowing it to run for as long as possible. I figure if i can disperse heat with a combination of small heatsinks and a fan, i can minimize the size; however, i will need more capacity (mAH). This is why i think the step up from 3 g's to 5 will be effective.

Timmeh: I have not yet been able to find a 3v-8v converter online. I am not really educated that well as to electronics, so could this go by another name? I suppose that because this new battery outputs the same amount of voltage as the last one did, the same converter is required.

I was also able to open up my N64 today and take a look around (the last screw wouldn't come out, but it wasn't anything a hacksaw couldn't handle...). It still works. I haven't touched anything on the motherboard other than removing the big aluminum heatsink (not the ones directly over the chips). I can already tell the soldering and electrical rerouting will be daunting, so a easy electrical guide would be awsome here.

Thanks for the help if you can. I only point you out because you seem to be the only one who knows what the hell they're talking about here.

I am familiar with how a transformer works, after all who doesn't enjoy playing with flyback transformers? I did not know that a DC-DC regulator operated on the same induction principle, though.

heh...are you sure it isnt a flyback converter instead of transformer? A flyback is actually a type of DC-DC converter, it just uses a transformer to provide isolation.
Anyway, I thought the 3.3V line on the N64 was the one that took the most current? The more current that's drawn through a DC-DC converter the worse the regulation, so if it's fine at 3.3V it should be better on the higher voltages.

Uh no a flyback produces like 18000 volts...That wouldn't be good for your n64...

if you think you can do it, here is a converter. its not as "plug and play" as the other ones you can get, but it "requires minimum external components"

http://focus.ti.com/docs/prod/folders/p ... 65131.html

The TPS65130/1 is dual-output dc-dc converter generating a positive output voltage up to 15 V and a negative output voltage down to –15 V with output currents in a 200 mA range in typical applications, depending on input voltage to output voltage ratio. With a total efficiency up to 85% the device is ideal for portable battery powered equipment. The input voltage range of 2.7 V to 5.5 V allows the TPS65130/1 to be directly powered from a Li-Ion battery, from 3 cells NiMH/NiCd or alkaline batteries. The TPS65130/1 comes in a small 4 mm x 4 mm QFN-24 package. Together with a minimum switching frequency of 1.25 MHz it enables designing small power supply applications since it requires only a few small external components.

make sure you get the TPS65131, with 2A max output

you will need to make a circuit board and get some capacitors, resistors and inductors in order to use this... the chip itself is smt. its not for noobs.

I really am not that great at electronic wiring or circuit board manufacturing. Unless I can find a guide somewhere on the net as to how i would built the board, i am not sure if i can use that converter

Also, i am wondering if this converter is still nessecary as a component given i have the same voltage but different capacity with this new battery? Would i require this component to run the unit or rather is it a optional power conservation device?

I really apologize if i seem repetitive and/or annoying by asking all these questions. I just want to make sure i get this right the first time without falling into one of those "Damn, i didn't think of that..." moments

Ok so i looked around and found this page:

Can anyone tell me if any of those converters will work with this battery:
