In this detailed tutorial, Chris Buisson demonstrates the process of creating a custom 36V e-bike battery using recycled LG MH1 18650 lithium-ion cells sourced from used battery packs. The video provides a step-by-step guide to safely disassembling, testing, and repurposing battery cells, highlighting the importance of careful cell selection and capacity testing. Buisson begins by acquiring used battery packs from Battery Clearing House and meticulously inspects and tests the individual cells using an Opus smart charger to determine their remaining capacity. He walks viewers through the critical steps of cell recovery, including removing nickel strips, grinding cell surfaces, and selecting cells with similar capacities to ensure balanced performance. The tutorial covers essential tools and techniques such as using a spot welder, applying fish paper for electrical insulation, and implementing a Battery Management System (BMS) to monitor cell voltages. Buisson emphasizes the potential risks of battery building and strongly recommends thorough research and careful practice. The video culminates in the successful creation of a compact, custom battery pack designed for an MX350 electric bike, demonstrating how recycled cells can be transformed into a functional and potentially cost-effective power source for electric vehicles.
