"Lithium ion Battery Training" (how to build your own battery packs). Do you want to learn Lithium ion and Lithium battery training, are you in search of how to build Lithium ion and Lithium batteries. Are you seeking for Advanced knowledge on how to build lithium ion and Lithium batteries for -:

• Home energy storage (solar backup)
• Electric cars
• Rc vehicles and drones
• Electric bicycles and skateboards
• And everything else.

If yes, Online Training Ng has brought an intensive step by step online training for people who want to learn how to build lithium ion and Lithium  batteries packs. This training contains the complete A to Z guide of how to build any lithium ion and Lithium batteries packs of any sizes and voltage. This is a Beginners step by step guide on how to build a Lithium ion/Lithium batteries from scratch. Lithium ion/Lithium batteries can be dangerous. They contain a large amount of energy in a small volume, and are specifically designed to release that energy quickly. When used properly, they can be a safe and efficient way to power nearly anything. However, when used improperly or carelessly, lithium batteries have the potential to cause devastating fires that can and have resulted in loss of property and life. Lithium batteries have existed in various forms since the 1970’s, and innovations in the 80’s and 90’s have led to the familiar lithium battery cells that we know today. Current research on lithium batteries has produced battery cells capable of extreme performance, for example, 100% recharging in just a few second. However, these current advances are strictly experimental and won’t see commercialization for many years, potentially decades. The information in this training covers the types of lithium batteries that are commercially available today and will likely remain available well into the future.

Uses For Lithium Batteries

Today, lithium batteries are used for a seemingly endless number of applications. They can be found everywhere from electric vehicles to NASA’s spacesuits. Due to their lightweight and energy dense properties, lithium batteries are perfect for an incredibly wide range of applications. In the past, lithium batteries were mostly used by original equipment manufacturers (OEMs) for use in consumer products. These big manufacturers built lithium batteries suited to their needs for specific products or large clients. If a hobbyist wanted a battery size or shape that didn’t exist, he or she was out of luck. However, today there are many lithium batteries and cells that are readily available directly to consumers for use in, well, whatever we want! I was introduced to the world of custom lithium batteries during my time spent working in the electrical/electronic industry. I have been building lithium batteries for electric gadgets for years, largely because the number and variety of lithium batteries available to the consumer market has always been frustratingly small. If I wanted a specific size battery pack but it didn’t already exist, I had no other choice than to make it myself. This opened up a whole new world to me. Suddenly, I could build batteries of any voltage, any capacity and most importantly, any size and shape that I wanted. But Do It Yourself (DIY) lithium batteries aren’t only limited to the world of electric gadgets. There are thousands of applications for DIY lithium batteries! Even though electric cars are becoming increasingly available in the consumer market, it can still be cheaper (and more fun) to build your own. Many people convert all kinds of vehicles into electric vehicles, and they need batteries to do it. Unless you want to buy an expensive, purpose built electric car battery, you’ll need to know how to assemble your own large battery pack from lithium battery cells. Just like electric vehicles, home batteries are also becoming increasingly popular. A lithium battery in the back of your closet or hidden in your garage can power a house for days in the event of a power outage. They are also great for storing energy that has been generated on site, such as from solar panels or wind turbines. Home battery storage systems like the Tesla Powerwall are great OEM products, but you can still build your own custom system suited for your unique needs. All you need is the battery know-how! Drones, wearables, backup batteries, toys, robotics and countless other applications are all ripe for custom DIY lithium batteries. This training will teach you how to design and build lithium batteries for all of these uses and more. Prepare yourself, because by the time you enroll/completed this training program, you are going to be full of knowledge and rearing to go out and power the world!.
