Help WIth Screen install. First build

[kpx4890]

I am thinking about making a portable wii and the wii power supply is 12v 3.7a and the screen I got is 12v 2a. The screen came with rechargeable batteries but I was thinking of taking them out and using a 4400mah 14.8v battery for the system and tv. I was going to have everything wired to the battery. I wasn't sure if I should get a 12v battery and does the difference in amps matter between the TV and system cause they are both 12v.

Please dont start two of the same topic with different subjects.

Voltage is voltage. But when the amps drop, so does the voltage. This is where a protection circuit is needed.
4400mAh is not enough to power what you specified.

So i found another battery with 10400 mah and 11.1v average but the range is 10.4v-12.1v with pcb protection included here is the link http://www.all-battery.com/Li-Ion186501 ... zmap=31800" onclick="window.open(this.href);return false;
