Hello all,
I read a post made about rebuilding laptop batteries, and since folks seemed to have some understanding, i figured this would be the right place to turn.
I'm about to start a project for myself, trying to build a nice mobile system. Something to let me have my digital media from the house with me on trips. I'm gonna be using a Mini-ITX setup, and i am planning on trying some kind of battery pack for it. How i'm gonna case this whole thing together will be based upon how i'll have to set up the power grid for this little bugger.
For the test, i was considering buying a battery pack and the charging circuit, and using a laptop as a reference for the interface to the board. I can get a DC to DC converter for the motherboard. Because the whole system will function on like 60W or even less (though i wanted to have 90 as a target, but that's beside the point), i wasn't too worried about the potential output of the power system, just the ability to sustain a charge for a while.
I can purchase an AC->DC brick that will just plug into the motherboard, so if i can't use it without AC, that's not a HUGE problem, it's just a step away from the design goal.
So, what all would i need to stuff into this computer to make it work without a wall? Obviously a battery (LiIon, presumably), and the charging circuitry, which (i assume) will allow the system to run off a wall plug when available.
I don't know how clear i am, as my writing follows a wandering mind a lot.
Obviously there are a lot of places i don't understand (i don't know HOW a charger can interface with a motherboard, for instance), so i'll be a bit of a sponge for a while here, but thanks in advance to anyone who can offer help.
