how long will it last?

[new york cheech]

i have 6 1.2v 2000mah AA's, i have a ps1 screen with a 7808 regulator hooked up to it. how long will the n64 last on a full charge?

i would recomend ditching the regulator seeing as it wont start with it, the screen can run fine off 6 AA Ni-MH i would guess over hour and a half

Depends. Did you do the LED mod on the screen? I think the screen with the original backlight system draws close to an amp. I'm not sure how much power the n64 draws, but I'll base my estimate on 500mah. So I'm guessing you'll get about an hour and a half out of it on a 100% full charge.

are u saying the screen can handle 9 volts? i dont think ni-mh i dont think, they are those "charges in 15 minute" batterys, IC3 batteries is what it says, it might be ni-mh, idk

Those IC3 batteries are so cool, but they are not sold anymore here, what happened?

i meant 6 1.2volt rechargeables your screen will run off them straight that is how my snesp's screen is running

oh thanks thats good to know that i dont have to use any regulators, it will save me some battery life

The whole shebang will run for about 1 hour if you a) use a regulator to lower the 7.2v to 3.3 for the N64 and b) you mod the screen with 6 white LEDs. The N64 draws 1.3-1.6 amps of power, while the screen draws about 500mA when modded. However, if you get a DC-DC convertor from digikey, the N64 will only take about 850mA max @7.2v, so you'll get a little under 2 hours instead. I suggest you look for some 2,500mAH AAs, you'll get better life and I've seen 8 and a charger for about $25. They are the same size, but you'll get more playtime out of them.

ok but im not using a regulator
3 1.2v batteries in series powers the 3.3v line and i dont want to mod it so without any regulators what the total play time

maybe talk to g-force or mike jones or see how long it will run yourself im pretty sure it will go over one hour

[usbcd36]

Well, you'll get a little over an hour on the system and a little under 2 hours on the screen. If you were modding the screen, you'd get a little over 4 hours instead (*comparison*). Trust me though, you'd be better off using a 7.2v 3 AH RC pack from RadioShack and DC-DC converting the power down for the N64…

usbcd36 has a good point and segasonic fan is selling some nice batteries right now in the post with the charger

its your portable do whichever you want

Well, you'll get a little over an hour on the system and a little under 2 hours on the screen.

i dont think u get what im doing, all the batteries are hooked together.

heres a quick diagram i made

[usbcd36]

Then you'll get…about 50 minutes total, except the batteries that are not part of the 3.3v will still have about half of their power remaining when the others are dead.
