1. There is no bottom, Just sides walls frames (HDPE sheets will form the top/bottom walls)
2. Corners will have a Rad. 1mm? or cutting tool dia.
3. I forgot to mention the Liquid fill hole. On 1 side of the 8cm sides, need a 2mm hole in the center or 4CM from the edge.
The Drawing can show the hole. Yet when making the mould, maybe easier to drill the hole out as to creating a Mould??
Thanks and looking forward to building
This could also be printed with 3D printer HDPE Filament.
Yes that is Correct Zinc Bromide Batteries. I have a way to create on a small scale and once we get set up, can mass produce, and open it up for others to Create
The Battery is getting 1.85V 3A with 10K cycles at this time. Yet we are looking to get more with bigger batteries in the future. We want to create a battery for Charging cell phones first.
