Ebay Keyword: Batcap or Alumapro

batcap is gonna be better than alumapro. the alumapro's simply cannot charge/discharge fast enough. but if you want to get down to it, a cap in any form is worthless in my oppinion. you are better off fixing the problem rather than putting a band-aid on it. get bigger power wires, a better battery, better alternator, upgrade the big 3, whatever you have to do, but avoid a cap.
