[QUOTE="klassic, post: 855622, member: 559732"] Lets say that is true. Wouldn't then the alternator and battery be responsible for charging the cap instantaniously everytime it discharges (at the tune of 70 amperes per second according to you for a 5 farad cap)? How is that any less strain on the battery and alternator? When will the battery and alternator have a chance to rest or less of a load to feed where it wouldn't before? And we are talking about feeding 1500 watts worth of current here (which is draining more than 70 amps continiously). In a system this big seems cap is just another stop for current to pass through on its way to the amps. From what I understand a cap is only able to discharge slowly (if thats what you are trying to say) when the load dictates it (like when the load is small enough only a small amount of its storage is required). But when the load as much or more than its storage capacity (which a 1500 watt system far exceeds) by nature it discharges nearly instantaniously. Is that not true? basically I dont know what you mean by "it will hold 70 amps for seconds at 14V". It will hold 70 amps all day if there is no load to dictate it being discharged. If it is discharging the load (demanded by the amps) how can it be "holding" it for seconds" and if that is so how is that helping quick transients which is the whole reason for using a cap?
