well I wanted to show you guys something kind of cool that I made y'all are familiar with my solar thing well what I did is I've disconnected my solar it's not connected anymore to my charge controller I've got two 100 watt kits coming in and it's coming out right here at 21 volts and it's just coming directly into here there's no battery it's just straight solar power so it comes in here 21 volts goes through the little 12 volt regulator and these are 3055 transistors and it comes out here at 12 volts these are supposed to be 10 amps apiece I highly doubt it may be 5 amps apiece if they say they're rated 10 the heat sinks are kind of small this is just a test thing and I put this capacitor on here just so it would have some type of a little bit of a charge in it so whenever you play like in music or whatever it's got some kind of almost like a battery but not and I've got hooked it for
