Lithium-ion batteries contain 2–4 kWh of stored energy — enough to cause a serious fire if mishandled. This episode explains exactly how to store eFoil and jetboard batteries safely, protecting your home, your equipment, and your insurance coverage.

What this episode covers:

  • Why fireproof aluminum storage boxes are the current best practice — tested by E-SURFER since 2017
  • The Zarges box + Cirrux fireproof cushion combination: why this pairing outperforms alternatives
  • Critical rule: one battery per box — storing multiple batteries together multiplies the risk exponentially
  • Ideal storage conditions: 10–25°C, dry environment, 40–50% charge level
  • What happens when a battery is dropped: invisible internal damage and when to contact the manufacturer
  • Charging safety: always supervised, on a flat dry surface, never when the battery is cold
  • Insurance implications: yacht and boat insurers increasingly require certified fireproof battery storage
  • Regular inspection: cracks, bulges, corrosion, leaks — what to check for

For most riders, a proper fireproof storage box is the single most important safety investment after the eFoil itself.
