   Good Read, just needs to have some specific suppliers for parts.Very good read, however, it would be nice to have some information on where to get things like BMSs and cells. Also would be nice to have more information on E-BIke batteries in particular.

   Lot of great nformationLearned a lot about lithium batteries. Too wordy, lots of repeats, book could have been half the size without leaving any thing out. Still a great read.

   The Gory Details of Ebike Batteries — What You Need to KnowThere’s a lot of good information in this book, and it is geared for ebikes. It’s important to understand the basics of batteries if you want to build a bike and, in particular, a battery. The book discusses, rather briefly, why you can’t build an ebike battery with the spring type battery holders people use for AA cells. They are just not electrically efficient enough to work.Ideally, people would learn the basics about the cells. This concerns proper charging and then matching cells and cell configuration to the discharge needs of a specific bike. If you know how to do this, the next hurdle is to assemble a pack from cells. I keep hoping there will be what I call the “insta-pack”. The Instapack is something you could use to assemble the pack without a spot welder. The author has a version of this, there is the BatteryBlocs system, and there is an Indian version similar to the Blocs system. I really hope something like this catches on. I don’t see the general public wanting to spot weld packs. This book lays out the dangers in minute detail. You could almost say this book discourages assembling a pack with a welder.Ideally we will end up in a world where people can DIY an ebike battery. The first place to stop would be this book. I’m hoping people won’t need spot welders. If people could buy cells from reliable vendors, at good prices, and assemble them in a couple of hours, it would change the ebike world. DIY is the only way to go for a good ebike at a decent price. I’ve built three and they are very reliable. The problems I run into are the stresses of going quite a bit faster. You need suspensions and you need to get ergonomic bars. I’m not locked into a design. I change stuff all the time.This is a serious book about ebikes. If you think you are interested in ebikes, buy this book. It will tell you what ebikes really are about, even if you never touch a spot welder. It’s a march of technology and the limited needs of an ebike match the cells that are out there. So ebikes are kind of the cutting edge, and the tech works. But it’s not simple and it’s worth understanding, just for the nuances of charging and life cycles of packs.

   InformativeThis book gave me the background knowledge and confidence to tear apart a DOA e-bike battery I received from China (the manufacturer support was nonexistent). I was able to quickly drill down to find that the BMS of the battery needed replacing and after ordering that very inexpensive part, I revived a battery that otherwise was a several hundred-dollar lead weight.

   A must read !Easy understanding for the beginner, most of us followYouTube but lack of safety and practical techniques.Yes, requires a few calculations and math.

   Beginners Guide to the Lithium Batteries GalaxyExcellent book because I have basic mechanical knowledge this book is written in lamens terms, with I like. This will give any half wit person the knowledge they need to understand the battery building fundamentals. This book is written as a friend explaining the basics of lithium batteries. It teaches you the calculations needed to design battery packs a voltage ranges. The reason people are not liking this book is because battery building is not a exact constant voltage and I’m sure this confuses newbie battery DIY’ers But the book does explain this and give knowledge that there are ranges and these are not designed for every application. The book is a great stepping stone of knowledge and by no means meant to be a replacement for a electrical engineer. Use knowledge with a degree of understanding and consult an electrician if you feel uncertain with your design or if your application use area could cause harm in the event of a failure. This is also sated in the book this is a stepping stone basic knowledge book. This book gave me the knowledge I was looking for after attempting to search you tube with no luck find detailed knowledge. This book connected the dots on my understanding. I would definitely recommend this book for beginners to get the staring knowledge and concepts here to see if you wanna take the next step.

   Straightforward to understandThe book covers all the bases and gives a rounded view of the subject. The writing style is straightforward, and somewhat informal. If you are an engineer you may feel that some of the points are laboured or perhaps over simplified and that the information could have been contained in fewer pages – but I guess it has to appeal to a wider audience than just those who already have a technical background. Michal Toll is obviously an expert and his detailed knowledge comes across in the text. After reading the book you will be able to differentiate between those YouTubers who really know what they are doing and are doing it safely and those who are creating a functional battery with scant regard to safety with dubious reliability and quality (!) The book is very easy read with good information. Even though I have a mechanical engineering degree and 45-years of industrial experience and did not find the book in the least taxing, I would nonetheless regard it as a good primer in lithium battery technology. (Kindle edition reviewed). Considering the highly variable quality of YouTube information, this book is worth the price of admission to get the right information – think of it costing about the same as four good quality 18650 cells..!

    Really good foundation bookGot this book for my brother and he is very pleased with it. It is a good basic summary of the basic information on how to make your battery with helpful schismatic. This is definitely not ment for people who are professionals and want to go into greater details but it provides really good basic knowledge and is useful for people that want to start making their own battery
