    What this does and doesn't tell you

    • Lithium packs need a BMS to protect each cell. Never build or repair lithium packs without the right knowledge and gear.
    • 240V AC mains can kill. In Australia, work on household mains wiring must be carried out by a licensed electrician. Low-voltage DC systems can still deliver very high current.
