Genesis2 portable batteries
Moderator:Moderators
I've almost finished my Genesis 2 portable but I haven't got a battery yet... What do I need to power it for about two hours (including none led-modded 4inch lcd screen)? I've got some 6V Ni-Cd batteries laying around though I heard those are not good.

yah Nicad are pretty bad...
is it a PSone screen (or somewhere around the ampage of 1Ah)?
if so (I'm not an expert on the amperage of v.2 gen)... maybe 6 Nimh (probably 2500mah or more would be ideal) AA's wired in series (voltage increase) should do the trick. if you want to know the voltage of gen. 2 you'll need about a 7.2volt minimum for it. (7.2 volts are probably ideal)

I've taken some pics of my progress. It's a crappy camera and I suck at taking pictures so don't start complaining.
These are the buttons I've put in an alu plate to try them out. I've got some issues with the start button and the C button but I think the Ic is broken...
This is an overall view of my progress (notice how messy my working space is ), everything works though you can't see it very well on the picture.
Overall view, again but this is how the layout will probably be.
This is a custom board I made. As you can see I've relocated some outputs and the Brightness and Contrast knobs. You can also view my crappy soldering on this pic.

I hacked my first sega a lot and it got totally screwed up so that's why it's so big. And for the traces: try soldering with 3mm solder and you'll see what you'll turn out with. Also It look very big but actually the whole thing fits inside a Sega case without metal shielding and btw I said before that the buttons were only temporarly.
Today I've gotten a Ni-Mh battery from a friend for $7. Which is very cheap because it retails at $97! The battery's specs are: 14,4V /Ni-MH 3500mAh. It is a Laptop battery made by ERTH electronics for use with Panasonic equipment btw.
I have some questions though:
-can I open it to take the cells?
-how do I open it? (it has no screws and consits of two molded plastic forms pasted together)
-how do I charge it (I think there is an internal charching circuit since it retails at $97)
I'll post pics if you need any.
EDIT: I've opened it up (Swiss knife) and there are 12 cells rated at 3500 mAh / 1,2V inside. To my dissapointment there is no internal circuitry inside. So the only thing I need to know now is how to chrage it...
Also some of the cells are oxidated which means they are probably not that new.
