Need battery help on portable n64

Post by remopedking » Thu Dec 29, 2011 2:47 am

Hey guys, making a portable n64 and had a couple questions about batteries for the board and screen.

Ok I am running a 7" lcd 4:3 screen that runs off of 12v..
So here is what I had planned

the batteries are super small 3.7V 650mah lipos.. they are wired in sets of 3 in series.. totalling 11.1v and 4 of those packs are wired in parallel

1. My question is first of all will this work? i don't see any problems with it unless i am missing something?

2. Second, will 1 pcboard work for charging all batteries at 11.1v and are lipos an issue with charging?

3. The last question I have is what is the approximate total run time of this setup pushing to the 12v 7" lcd 4:3 screen and n64 board?

Any help here would be amazing. I have zero electronics knowledge so i'm looking for some help from anyone with experience on this. Thank you in advance!

Where did you find a 7" 4:3 lcd? I am having trouble locating one. I assume it runs at 640x480?

You only need 7.4 volts on the 12V line. Saves batteries. Instead of of using sets of three in series, use sets of two.

EDIT: I see your screen needs 12V. I'd recommend a smaller screen anyway, but if you need 12V, disregard what I said.
