This blog post provides a quick overview of what is involved in the battery pack potting process. Battery potting can greatly aid in stability and help to optimize the performance of your finished custom battery pack. Potting materials are used to provide mechanical reinforcement to housed-assemblies and to protect components against exposure to harmful chemicals, moisture, mechanical shock and vibrations, and other hazards.
Some additional benefits of using battery potting include low cost shells, hermetic like seal, and good electrical insulation.
