I’ve designed a battery testing board (the initial version is discharge only) specifically for testing 18650s. The aim is to have a “cheap and cheerful” board that is accurate enough to be useful. I’m

Battery cage and 18650 discharger update
I’ve done some more work on the battery cage and it’s nearly finished. I’ve cut out, bent and riveted all of the front and rear aluminium sheet now. Soon I can start working on sealing all of the edge

Progress on the battery cage

More work on the battery cage + Type 1 charging port
I’ve now worked out pretty well how the battery is going to come together. There will be 3 main packs in the bulk of the battery cage, and a fourth one sitting on the top. There will also be a couple

Initial battery pack design (15kWh, 3 modules)
So our initial battery pack design features 3 individual battery packs that can work independently and separately from each other. This will allow us to start off with just 1/3rd of the cells and give
