Cord to Cordless Jigsaw Conversion from 110V to 18V | RYOBI MJ-21

I have 5 electric jigsaws that runs with 110V. It is hard for me for working outside or far away from electric source. I decide to choose one of them and convert it into cordless power tool. ”In condition I fail, I still have 4 tools left, but if I succeed I learn something new and have video for you” this is what think before I start the project.
