PWR-Foil: The Art of High-Performance Battery Engineering
PWR-Foil: The Art of High-Performance Battery Engineering
When we think of efoiling, we picture the glide, the silence, the sensation of flying. But this magic would be nothing without a perfectly controlled energy source.
After exploring the core of the propulsion system in a previous article — motor, mast, electronics — it’s now time to dive into another key pillar of performance: the battery.
At PWR-Foil, the battery is not just a component: it is the true engine of trust, power, and durability. A technological powerhouse, the result of advanced development, where every detail matters.
A Unique Layout for Natural Cooling
From the initial design, we made an engineering choice that changed everything: the battery is positioned underneath the board. This unique layout ensures permanent natural cooling through constant contact with air and water on the battery cover.
This aluminum cover was entirely designed to maximize heat dissipation between the cells and the external environment. Effective cooling means not just safety and durability, but also consistent performance — even in the most intense usage scenarios.
Top-of-the-Line Cells with Zero Compromise
PWR-Foil exclusively uses the most reliable lithium-ion cells on the market, supplied by Samsung, a global leader in electronics. These cells deliver exceptional charge/discharge capacity and unmatched energy efficiency.
But excellence goes beyond the cells: all battery components — connectors, PCBs, protections — are sourced from top-tier global suppliers to ensure unrivaled reliability. No compromise.

Custom Electronics Management: Built-in Intelligence
Battery performance also relies on software. At PWR-Foil, our BMS (Battery Management System) software is developed entirely in-house based on a strict and detailed specification.
This invisible brain ensures precision energy management:
- Accurate power delivery
- Smart thermal monitoring
- Auto-sleep during long inactivity
- Cell balancing
The result? Reliable range, steady performance, enhanced safety.
Optimal Voltage for a Sporty Machine
The nominal voltage of 64.8V reflects PWR-Foil’s core philosophy: performance, responsiveness, sportiness. This level of tension enables optimal motor rotation and delivers the dynamic, punchy propulsion that defines our Revo boards.
Absolute Safety
Every detail is designed with maximum safety in mind:
- Robotized assembly to the tenth of a millimeter, ensuring flawless industrial precision
- Smart connectors that only activate power when the battery is fully and securely inserted
- Dual sealing gasket around the casing
UN38.3 Certification: A Global Standard of Excellence
Thanks to all these features, PWR-Foil batteries are UN38.3 certified — the strictest international standard for lithium-ion battery safety. This ensures superior quality and authorizes air cargo transport, despite their high power.
UN38.3 is a global regulation set by the United Nations governing the safe transportation of lithium-ion batteries, especially by air.
To be certified, a battery must pass rigorous tests simulating extreme conditions during transport. These include:
- Altitude simulation (pressure test)
- Thermal cycling (temperature extremes)
- Vibration test
- Shock and impact test
- External short circuit test
- Overcharge test
- Forced discharge test
- Crush resistance test (for specific battery types)
These tests ensure there is no risk of fire, explosion, or leakage — even in the harshest scenarios.
Two Formats, Same High Standards
No matter the model, each battery is a concentration of technology, safety, and performance — all designed to help you fly farther, longer, and with absolute confidence.
At PWR-Foil, innovation is built cell by cell, so that every ride is a controlled surge of power.
