Project Lithium — Foil Drive Assist MAX Power Battery (Aftermarket)
More sessions, more distance. Project Lithium’s aftermarket replacement battery for the Foil Drive Assist MAX is built with Molicel P45B 4,500 mAh lithium-ion cells, squeezing 534 Wh into the same form factor as the OEM unit — giving you a meaningful capacity bump over the stock 498 Wh pack.
Hand-assembled in Auckland, New Zealand, this is a purpose-built repack using matched, Molicel P45B 4,500 mAh cells with integrated BMS charging protection for over-charge.
⚠️ Important: This battery is NOT water resistant. Use with appropriate protection and keep away from water ingress. A lipo bag is strongly recommended.
