Vacuum bagging the systems battery. To waterproof the batteries, we used the same technique that we use for vacuum bagging composites to bag the batteries and protect them from moisture. Silica gel packets pull moisture out of the air inside the bag, which lowers humidity and prevents condensation.
The motor battery also gets vacuum bagged and desiccant packaged with it.
The battery box. It’s built out of fiberglass because carbon fiber conducts electricity, and a glass box was easier to work with for this component.
Max partially buries the plaster bulb mold. This was for two reasons- it would keep the mold in position, and provide a shield between the mold and the people pouring the lead (if the moisture content in the mold plaster is too high, the mold could explode).
