In this detailed tutorial, Rob Cameron walks viewers through the intricate process of constructing a custom 52V eBike battery for a Rad Power Radrunner 2, providing an in-depth exploration of battery technology, component selection, and assembly techniques. The video begins with a comprehensive explanation of battery theory, covering voltage, capacity, series and parallel connections, and the fundamental principles of lithium-ion cell configurations. Cameron meticulously guides viewers through battery shopping, demonstrating how to select appropriate 18650 lithium-ion cells by examining critical specifications like capacity, discharge ratings, and pricing. The tutorial covers every stage of battery construction, including pack assembly, precise welding techniques using a specialized battery welder, strategic wiring of the Battery Management System (BMS), and professional heat shrink application. By using Eve 33V 3200mAh cells, Cameron creates a 14s8p battery configuration that doubles the original battery’s range and potentially increases top speed. The project emphasizes safety, technical precision, and practical DIY skills, offering enthusiasts a comprehensive roadmap for building a custom, high-performance eBike battery with enhanced capabilities.
