In this video, I made a DIY Power Bank with 40AH 18650 cells from 18650 salvaged from old laptop batteries. This Power Bank charge laptop, phone, other power bank and even run sewing machine. It have 12volt outlet and torch light for camping. this power bank is connected with the solar setup, so its charged and adds more capacity to my solar system setup.

I used my previously made 40cell Charging & Capacity Testing Station to know the capacity of the cells for repacking the cells into a proper battery packs.

I was contacted by JLCPCB a few months ago about their interest in sponsoring some of my projects and providing me with pcbs to speed up my projects. So I decided to restart my 18650 battery pack build project that I've always wanted to do for a ago time but got busy.

WARNING: Do everything at your own risk, lithium batteries can catch fire or explode if mishandled. This power bank requires a more than a basic understanding of electronic to complete.
