Introduction: Make a Cheap Lithium Battery Pack

With some few hacking, you can turn your old phone battery into a powerful Lithium battery pack. This is a great alternative for the expensive Lithium Polymer battery packs. These things work well with Arduinos, DIY robots, speakers or any project that requires a high current power source.

What’s The Secret?

The secret is simple. Obviously, phone batteries are designed to work with phones. A fail safe circuit is added on top of the battery to prevent the battery from draining too quickly, overcharging and exploding. By removing the limiter, you’ll be able to get full power out of those mobile batteries.

Why Upgrade To Lithium Batteries?

Lithium batteries are one of the most powerful batteries existing today. They are small in size, they have high charge capacities, and also have a high “c” rating. Lithium batteries are 6x 10x more power than AA (NiCd/ NiMH) batteries.

I just got back from our vacation in the beautiful islands and beaches of Palawan 🙂 I’ll be posting a series of projects this month, including my: DIY CNC Build, Electricity Generating Footwear, 7 Homebrew Arduino Sensors, High Precision Obstacle Robot and 10 other projects waiting in my draft list :)WARNING: This is a dangerous project! There are risks in attempting the hack. I or site is neither liable if any of you gets injured. Don’t forget to wear safety gears like eye protection and gloves. Lithium batteries are prone to explosion.
