This is our new 100 Volt lithium ion battery pack for the next electric go kart project. The two modules shown below will be connected in series to obtain a nominal voltage of 100V and the pack has 46 aHrs of energy storage capacity. The soft drink was included for relative size comparisons. We connected the lithium cells with .25mm thick pure copper using a professional-grade pulse arc welder. We are also using a “Dilithium” Battery Management System to properly balance the pack. The pack utilizes 10 thermistors attached all around both modules to constantly monitor cell temperatures.
