Re: [PSUBS-MAILIST] OSS Modeling Ideas
Try pressure compensation with epoxy. If the battery
hull is the correct dimensions, it might just be
possible. They sell thermal conductive, electrical
insulative epoxies that you can fill with glass beads.
This is somewhat expensive, and completely
irreversible,
but would work.
