🌊 EM3ev Marine-Grade Battery Systems for Electric Surfboards

Marine-grade EV batteries don’t just face water — they fight vibration, corrosion, and relentless heat. 🌊⚙️

Every electric surfboard battery we build is designed to survive real-world ocean conditions — salt spray, thermal cycling, and high-current surges.
Our engineers at EM3ev spent hundreds of hours validating performance where it truly matters — under pressure, humidity, and waves.

Key Highlights 🔋
✅ IP68 Waterproof Validation — 200+ hours of salt-fog & immersion testing, 0% leakage.
✅ Vibration Resistance — 8g RMS six-axis validation ensuring continuous BMS data.
✅ Thermal Management — Dual-path cooling within ±2.5°C temperature delta.
✅ Energy Density — 245 Wh/kg, among the highest in marine EV applications.

“Our engineers don’t test in theory — they test under waves.” 🧑‍🔧

We have been told of an Aliexpress seller offering motorcycle parts, posing as us.

This person shared an image of what looked like our page, with some differences.

We have never offered any of our products on Aliexpress, Amazon or any other platform, except our own website.

What's more, we have only ever offered ebike-related items and our own batteries.
