I run a battery service workshop and take safety extremely seriously. Every course I publish starts with fire prevention, cell handling and when to walk away from a pack.

    Genuinely changed how I handle packs. The refuse-the-job module should be mandatory.

    Safety-first without being preachy. The cell-group walkthrough is superb.
