Hi All.
I am thinking of building a battery operated hi-fi. My intention is to get a reasonable quality car stereo system (CD, amp, couple of speakers, prob a sub woofer), and power it from a car battery.
Firstly, how much power can you get from a 12v car battery? How long would this last? (obviously this depends on the power consumption of the stereo, but any rough estimates would be useful)
Secondly, my intention would be to recharge the battery from a car/mini-bus, so it would be easiest if this could be done via the cigarette lighter socket. Also, the battery would probably have to be left on charge, so I would need a circuit that would stop the charging process after the correct amount of time (I have seen circuits like this on the net, but never for a 12v supply). How would I go about doing this?
Lastly, has anyone built something like this before? Any tips to consider? (it will be used outdoors, when camping)
Thanks a lot
