The No-BS Guide To DIY Powerwalls

Book excerpt: The Guide to DIY Powerwalls was the first of a 3 part series I started in May of 2020 during the height of the Pandemic that focused solely on creating a robust and extremely powerful power storage system similar to the Tesla Powerwall but on a shoestring budget. One of the requirements would be its easy intergration into other off-grid technologies. The search led me to discovering how to repurpose large and relatively inexpensive batteries from wrecked Electric Vehicles (EVs). This book consists of 113 pages broken down into seven chapters which are: Safety, Planning, Teardown, Preparation, Deployment and the P3 (Portable Power Pack) Builds. The guide walks you through determining your energy usage and needs, storage amounts, locating suitable batteries at the best price and converting them into a usable battery bank. This guide illustrates the conversion of a Ford C-Max battery module, but the principals apply to almost any EV battery out there. Although a seemingly daunting task, this book makes it easy with plenty of pictures, careful explanations and a sprinkling of humor. This book will be useful to everyone from the novice to the expert alike.
