Vintage Demolition Hammer Restoration Conversion

This is a vintage demolition Hammer from Japan. I think it is a vintage Makita power tool that was abandoned in Japan. This power tool isn't original from end user, it was repair by someone. I want to use this hammer tool in my farm by using battery. It is a challenging project for me to convert a big power tool like this into a battery, but finally I can use it with battery. You can see I using it at the end of this video.
I hope you find this video useful and enjoy it!
Furthermore, I am happy to receive feedback, suggestions to improve myself.
