Depending on certain factors..

both will isolate (somewhat) the alternator.

Though the cap does a better job at this.

But the batcap, will be able to hold on for longer.


So if you have a bug alternator that suites the purpose, then a cap would be the way to go.


But If you have a big ass system without the adequat alternator power, then a batcap will be able to save your behind for a longer period of time and/or at a higher intensity..



I wouldnt go for a batcap, cause I dont need that much power on that long of a period of time. Even if I did, I'd rather upgrade the alternator first/with a regular cap..



How much do they go for?
