Hmm....Thx for explanation, just I want to ask, if other ppl say that why the headlamp dim, and the problem causes on that?And I believe that u are experience seller than me, so if u don't mind, u can share out on experience why is it like that?Plus, I also tested out many VS, I found out that (Too high capacitance on 1 pcs of capacitor (i.e. 80K uF) will act very slowly can't filter ripple signal which happens at 1-50ms), as u said , is it really effect a lot?And maybe I din research so much on that....
Sometimes not even a 1st class wormbook eletronic engineer can know the answer, not to say you dun have electronic background at all.
Our car alternator is current limited device, means it generate finite amount of current (unlike our power socket at home, almost infinite as long as the wire can support). Big cap (or high capacity capacitor bank) will draw more current when it start to charge, and it charge slower due RC constant.
Why by putting high capacity VS can help to solve the light dim when compressor kickin??
Becos VS connected directly to the battery, hence it almost act as voltage buffer for headlamp. But be aware, when the compressor kickin, the voltage will dip and VS start to discharge to stabilize the voltage. The fact is after it discharge, it need to charge back as well, so where is the current come from? Alternator?? But if the charge current is reach its output capability due to too large capacitance? How??
It will draw current from other devices, such as your audio system (Because got cap inside too) and other circuit too, or it will overload your alternator. Outcome is more sluggish performance.
So, not higher capacity = better performance, there are still alot of background info that you never know that might bring other side effect. I'm not saying that your VS capacitance is too big, just that your mindset of bigger = better is totally wrong. Remember one of the buyer from your thread who said the car become sluggish after using your VS??
Electronic modification/addon need DRBFM (Design Review Based on Failure Mode), which you need to fully understand the basic of your compnent addon and list down all the side effect, clearly you don't do that because you not even know the basic of it.
