DIY Lithium Battery Pack using 18650 cells

This video shows how to build custom 18v lithium battery pack conversion for a black and decker cordless drill using 18650 lithium ion cells harvested from used laptop batteries. Cell layout, soldering and balance leads how-to will be discussed. It is important to use a low voltage alarm to ensure the battery does not discharge below manufacture specification. Also, use a lithium balance charger, such as iMAX B6, to charge the battery cells. Here's my video showing in detail how to convert the black and decker drill from nicad to lithium battery pack:    • Lithium Battery Pack Conversion Black and ...   Hope you find this video useful.
