In this deep-dive conversation, Cyril Coste from Duotone breaks down the real performance of the all-new Duotone Foil Assist — including honest battery runtimes, high-voltage power, safety systems, travel-approved battery design, and what riders can expect in waves, downwind, and everyday foiling. We cover the engineering behind Duotone’s high-voltage LiPo battery system, why it delivers consistent power longer than other foil assists, and how Cyril uses the system for 50–60 minute sessions on a 600cm² wing. He also explains their floatation design, airline-safe battery configuration, and how Duotone kept the system ultra-light without sacrificing output. If you’re comparing Duotone vs Foil Drive, curious about battery safety, or wondering how long the assist really runs — this episode has all the answers.
