Scooter Knowledge Base https://github.com/firebl0od/Scooter_Knowledge/tree/main This repository collects and organizes information about electric scooter setup, maintenance, and troubleshooting. The primary source material is a large Telegram conversation exported from the "VESC help" group https://t.me/VescHelpGroup. The goal of the project is to extract practical knowledge from the chat logs and document it in a structured, reusable format. VESC is short for Vedder Electronic Speed Controller. It is an open-source, open-hardware motor speed controller that allows for advanced customization via software (such as the VESC Tool app). It is commonly used in electric scooters, skateboards, electric bicycles, and robotics projects to provide precise control, regenerative braking, and sensorless operation, overcoming the limitations of standard closed controllers. The knowledge/processed/themes/ directory contains 72 professionally formatted documents covering: 28 brand dossiers covering controllers, motors, and BMS systems from manufacturers like Spintend, Flipsky, Makerbase, 3Shul, and more 44 comprehensive guides including: VESC tuning and parameter optimization Battery pack design and BMS integration Motor cooling and thermal management Conversion guides for popular scooter models (Ninebot, Xiaomi, etc.) Brake upgrades and maintenance Field weakening and high-voltage setups Diagnostic tools and troubleshooting All documents use a consistent, readable format with: Clean footnote citations linking back to source material Well-organized sections with proper headings Tables and checklists for quick reference Preserved technical accuracy from the original discussions #electric#scooter#bike#controllers#vesc#batteries#diy
