Through "trial-and-error", we discovered that approximatly 1,800 Amps of current works best for welding our busbar to the lithium ion batteries we will use in our racing electric go kart. We have spent countless hours (and "sacrified" countless batteries) performing this research but the experiments have proven very helpful in building a battery pack that can withstand the high-vibration enviroment of electric go kart racing. www.VenomKarts.com
