Can I put 14.8 volts into the Gamecube's power board?

[kylechu]

Well, my laptop battery from a broken laptop is 14.8 volts, and I was wondering if that would hurt the gamecube. If it will, is there something that would bring it down to 12 volts?

[Designer noob]

I think on the 12v line of the gamecube you can put anything from 15 to 12v.

[kylechu]

Well, has anyone put 14.8 volts into it and had their gamecube live to tell the tale? I don't want to fry it.

[Designer noob]

don't listen to me. lol, wait for someone really smart or read some stickies. Power is always talked about the beginning in each stickey usually. So, read the gamecube thread and you should fine the answer.

Also, you could always just get a 12v DC regulator from TI. I am looking for some, but they all cost like 28 bucks, but I know I can find one for way cheaper.

I read in Skyone's thread that the 12v line ran fine off of 5v but drew more milliamps. Don't know about higher voltages though.

[Designer noob]

kk, I think this is it. 4.5v to 17v input and a .8v to 15v max output.

NVM it says 14 pins so, I quess its a IC. But, it still does the job. (I think)

@kylechu,
Yes, the gamecube powerboard has ran on 14.8 volts before. Look at both of kasar's portables, they run on 14.8 volt batteries.
Also, the gamecube will use less amps if you use higher volts, but the total watts will be the same. However, I wouldn't do anything above 15v because it hasn't been done before and you risk blowing your board.
So yes, it will work.

[kasar]

well, my first one had a 12v battery.

my second portable have a 18,8v battery, and when the charger is plugged there are arround 19.50v I has been using it for long time and no problems.

I think gamevelver's GCp uses 2x 14,8v batteries in parallel, but not sure

yep, it is safe use 14,8v, the GC regulator board is a solid board, and very usefull, you also can use it to power other systems like n64 or similars (I tested a n64 a few time ago and works perfect)

so go for it man, you can plug the 14,8v battery directly in the GC regulator board without problems, so you dont need waste your time and money into aditional regulators wen the GC regulator board is doing a good job ^^.

just remember to check the battery polarity at least twice before connect it to the system

I also think 14,8v battery is the best choice for a GCp

good luck

Whoops, I was thinking that you always recommend 14.8 Volt batteries...
And 19 Volts!? Can the gamecube powerboard even take that much power?
Or did you regulate it?
14.8 Volt batteries are the bomb though because since the gamecube uses switching regulators it runs on less amps then, say a 11.1 volt battery.
The gamecube powerboard is awesome. I used it one time to power my dreamcast.

[kasar]

yep, I still recomend the 14,8v, them are like 12v ones, but you have some extra Volts will help until the voltage drops down, this helped me cause my TV bright came weaker when the mattery was arround 1/3 charge, the 18,8v are also to big, thats why my left so much space left inside my GCP case, the batteries used it ^^

btw, I used 18v batteries cause I had some laptop battery packs over here with the prot board and charger.

about the 19 volts, I plugged them directly into the power board, without regulate, yep, you can call me crazy, mad, or whatever you want, but it still working fine, that means the regulator board is "da bomb", or that my gamecube have "special powers ^^" wich others dont have, I preffer to think the regulator board is a piece of art ^^

I think you also are right 64M320N3, probably each more Voltage less Amp, I also saw the info at the stickies, this explains why my 18.8v 6600mah battery can work for a long time on my portable hehe


btw kylechu, take your time to choose the battery, my advice is choose batteries with voltage between 14,8v and 18,8v , take also a look at the amps, the gamecube + screen is power hungry, get also in mind how you are going to design the charging system, an other stuff. most of portables here have different batteries, so take your time and choose your favorite

[64M320N3]

So the Gamecube powerboard is "da bomb".
I was unaware that it could run off of such high volts without blowing. After all, it was designed for 12 Volts.
SS's GCp only ran for around 2 hours on 11.1 Volt batteries that are 6400 Mah, so since yours are such higher voltage I assume yours would run for a much longer time.
How much time do you get out of your portable, anyway?

[kasar]

well, sadly the difference may not be as good as desired , mine is arround 2 hours and few mins too, but I think my screen have some to do in there, my crappy screen eat arround 1A, and SS usually use psone screens, and probably he led moded them, this basically means my system need more power, and I also have two rumbles, the BBA, and the qoob pro modchip, last time I tested my system with a multimeter, it needs arround 2,36 A

now all we need is SS's system power consumition per hour to make conclusions

[64M320N3]

In other words your portable is horribly inefficient but still gets around the same battery life.
I'd say that's a plus! If you used your batteries with SS's setup then you would probably get a lot more battery life.
He used a qoob too though...

[kasar]

yep, probably my batteries will work longer time in SS's setup ^^

well, the qoob chip required power is almost insignificant, btw, not sure about the BBA

In other words your portable is horribly inefficient but still gets around the same battery life.

o.O ouch my poor wooden box

^^

[64M320N3]

Umm... sorry.
But you know what I mean, as for the screen is nice and big it also takes a not nice and still big amount of power.
And I love your little wooden box.
