28.8V Foil-Assist Battery

Description

Keep riding when the waves keep pumping. Paddle or motor back to the beach, swap in a fresh pack, and head straight back out for round two. This 28.8V (8S3P) lithium-ion battery is assembled and tested in-house here in Auckland, built around quality 21700 cells and a purpose-matched Battery Management System (BMS) for safe, reliable sessions.

Every pack is hand-built and load-tested before it leaves the bench. The integrated BMS manages charge rate, cell balancing, high/low-voltage cut-off, internal resistance and temperature monitoring — so you get consistent power delivery and long cycle life.

Designed as a direct-fit replacement or spare for popular foil-assist drive systems running an 8S pack.
