Think of these batteries as your Nitrous tanks. Like Nitrous, the ESC's instant boost is currently limited in duration, but unlike Nitrous, that restriction will gradually disappear as battery technology improves. Eventually, high-volume capacitors will allow for almost perpetual usage. Until then, a typical battery bank will yield several runs before recharge. And unlike Nitrous, our system will not cost you thousands of dollars in long-term refilling expenses. Most Nitrous users go through at least 1 bottle/week, and at $30 to $45 per bottle, that's a hidden charge of $1,560 a year, every year, forever. Think about it! With our system, you will never deal with costly refills again.
