about how much current does a snes w/ a sony 5" lcd draw?

can yall give me a suggestion on a good battery(s) to get? im looking to spend 50-70$ on batteries w/ charger (shipped)

Ah the SNES will draw between 1.1 and 1.5 amps. The best battery I know of is a Ni-MH 3000mA. If you're lucky you can find them at RadioShack, otherwise ebay is the best place to look, they go for about $20-30 each. The charger you can use is a R/C charger RadioShack sells, I believe they're about $15 for the charger.

One will give you about 2-2.5 hours of play. If you want more time buy two batteries and connect them in parellel, then you can get about 4 or more hours.

No, my old SNES draws about 500mA @ 7.2v. The psone screen (modded) takes 350 mA, so that's 750mA total.

I'm high balling it, better to be prepaired for the worst then not. Also not many newbies do the LED mod on the PSone screen.

it's a mini snes and i led modded the screen, so it should take about 750ma?

Yes, so expect out of that that battery I mentioned a little over 3 hours. Oh and keep in mind that games that use the FX chip (like Starfox) will consume more power, so you're time will be less.

NOOOOO! less playing time for starfox? what will i do? lol

Why don't you just use 6 Energizer AA 1.2v Ni-MH 2800mAh batteries? They are a lot cheeper than $50 for all 6.

Does anyone know how to calculate the runtime (hours, secs) of juice I can get knowing: the (milli)amperage and voltage? Thanks a lot..

snes draws about 450ma i think and so does a hipgear screen i think a psone screen draws aboutthe same also. so together you would have a draw fo about ~.9 amps or 900milliamps so wioth 2800 ma batteries you would probably get ~3hours i think thats right because that is about the playtime i get with my snes and psone screen on 2500ma batteries

Thanks for the info, but I meant some equation to input any amounts.

The numbers everyone mentiones for the power consumpsion of a system/screen is the amps per hour. So add the screen and system curent draw (amps) together. Then how many times does that go into the amps your batteries hold.

S+C=D : B/D=R

Screen + Consol = Draw : Battery(capacity) / Draw = Run(time)

VCR silly

V=C*R
C=V/R
R=V/C

V=Voltage, C=Current, R=Ressistence

So hold on a minute... how many volts and mAh does the PSOne screen take WITHOUT the LED mod?
