The book appeared a great asset of information about EVs either new built or conversion. However the information is more general and if you want to get it more specific this book is not in much help. I personally was skimming the information and did not read it thoroughly, as about 95% of informaiton is very common taken from the Internet. Instead of drawings there are just pictures which are great, but they are not in much help. I consider this book more as a good motivator and some kind of starting point in aquiaring information for EVs enthusiasts. Definitely is will occupy the easy to reach place on my bookshelf and wouldn't be covered by dust. In general I would recommend it to all hobbyist and EV curious people.
