I've got my 7w amp and 12v batt all neatly tucked into a RS project box. With jacks mounted on the side for Azden input and speaker, an on/off switch and the amp volume control. The speaker and Azden have hook & loop pads on them to mount to the box quickly. It's pretty slick. I'm getting ready to mount a DC power jack for charging the battery without having to open the box. Intention is to charge through this jack both at home with the wall transformer/charger, and via cigarette lighter adapter in the truck.
Now, realize, I don't know ANYTHING about what I'm doing here! I'm semi amazed that I was able to get it all soldered together this far and it all seems to work just great.
First question, regards how I'm going to wire in the DC power jack for charging the battery. My plan is to simply wire it into the same terminals that are coming off the battery to power the amp (two sets of wires soldered to the same terminals). I'd turn off the amp before charging of course, so that the circuit to the amp would be open and the "juice" would all go to the battery. Or, would it even be "okay" to plug in the cig adapter with the amp on, to run it off the cig adapter? Any problem with this? I'm just not sure if having it all "wired together" like that will hurt anything or not.
Second question. Assuming my simpleton plan above is good to go, is there any danger associated with charging the gell cell off my trucks power outlet? The battery I'm using is a 12v 2.9 amp. hour. Seems like the juice coming out of the cig adapter might be a bit strong for this little battery, without any regulation. Or is just not that big of a deal?
Thanks a whole bunch for all the help recieved so far, and any that you can provide on these questions!
