I have a basic knowledge of electrical circuits and electronics, but I need help with this next project of mine. I will be building a fan box with a computer fan. The fan runs on 12VDC, and I'd like the power source to be battery, with the option of an AC plug for times when recepticals are near. As well as to charge the battery, obviously.
I've been looking at battery packs, chargers, converters and the like, but I'm lost now. I know I'd like the charger to be "smart" or "rapid" so the battery can be plugged in for long periods of time without overcharging.
Could someone please let me know what type of battery/charger this would require, and where I could find one? Ideally I like it to function like a cell phone. All you see is a plug in, and the battery pack would be soldered within the unit.
This seems basic to me, but I'm having a time trying to find the right components.
