Get one big cap(2farad should be fine) or just add another 1 farad. Look on ebay for caps cuz you can find like a 15 farad for dirt cheap. Places like bestbuy charge $100 for 1 farad and $150 for 2 farad, the pricing is illogical and overpriced to begin with. You can get a yellow top batttery and another cap for under $300 easy.
