In this detailed DIY tutorial, the Electric Bike Laboratory demonstrates how to construct a powerful and affordable 72V 40AH battery pack specifically designed for electric bikes, particularly Stealth Bomber clones. The video provides a comprehensive walkthrough of battery pack assembly using six 36V 12.8AH Eco pack batteries, which are carefully disassembled, prepared, and reconfigured. The presenter meticulously explains each step, from removing the original battery casings and circuit boards to trimming plastic tabs and stacking the cells in a parallel configuration. The resulting battery pack is capable of delivering an impressive 9000W peak power and can be built for approximately $350-$600 USD. The tutorial covers critical technical details such as using a Daly 60A BMS (Battery Management System), selecting appropriate connectors, and applying protective heat shrink and mounting panels. By using high-quality LG cells and demonstrating a straightforward assembly process, the video offers an accessible method for enthusiasts to create a high-performance, cost-effective battery solution for electric bikes and similar high-power applications.
