Thrust To Weight Ratio*

Power to Weight Ratio is calculated by Thrust ÷ Install Weight. It indicates how much thrust a system produces relative to its weight, expressed as units of thrust per unit of weight. For example: 4.35 kg of thrust (Newtons) per kilogram of system weight. This ratio provides a useful way to compare different systems in the market, however real-world performance will also depend on the setup you ride, including your foil, board, conditions and riding style.

Energy Density ⌃

This is the amount of energy per kilogram of each battery. It is calculated based on Watt Hour ÷ Battery Weight

Airline Travel

Foil Drive batteries are subject to airline approval. Most airlines currently allow the transport of lithium batteries under 160 Wh, however, please check with your carrier before you travel.
