Building a Modular 18650 7s Power Wall

I have made many minor changes since this video to improve and simplify the manufacturing process. Check out my lattest videos and my update videos!

I'll make another video in a week or two of time lapse step by step building the power wall. this video is more of how I came to developing this final design. It took over a year of planning, design, test and failure to arrive at this stage. It was not easy and many parts were not available when i started building in Sept. 2017.

------------------------------

Hello! I'm Andy and this is my video log of designing and building the cheapest most modular and easy to fix, diagnose and build power wall. Watch my latest videos for updates and ask any questions if you're not sure.

Thanks for watching!
