  Safety & Usage Tips

  1. Use only a dedicated 12.6V lithium-ion battery charger with matching polarity to avoid damage.
  2. Do not expose the battery pack to water, extreme temperatures, or direct sunlight for prolonged periods.
  3. Keep away from metal objects that could short-circuit the terminals.
  4. If the pack swells, leaks, or emits an unusual smell, discontinue use immediately.
  5. Store in a cool, dry place with a 40-60% charge level for long-term storage.
