Converting a DeWalt 12V Cordless Drill from NiCad to Lithium LiFePO4

My DeWalt DW927 cordless drill uses 12V nicad batteries. I'm getting tired of replacing them with new expensive nicad batteries only to have them degrade after a year or two and stop holding a charge. I decided to try rebuilding one of them using lithium iron phosphate batteries (LiFePO4).

WARNING: Lithium batteries are dangerous and can result in fire! This video is NOT intended to be instructional or a "how-to" lesson. I am not a professional. Do not attempt anything you see here without first contacting a certified and/or licensed professional.
