I'm looking for a comprehensive course focused on lithium battery maintenance. This should ideally cover key topics such as troubleshooting, safety protocols, and best practices for extending battery life. I'm interested in both theoretical and practical components, as well as any certifications that could be obtained upon completion. Additionally, please provide information on course duration, cost, and whether it's available online or in-person. If you have any specific materials or resources that would be beneficial for hands-on learning, I'd love to hear about those too. Let me know how you can assist!
