Additional or replacement Lithium-Ion battery for the Foil Drive Assist system only. This product currently has a longer 3 week production lead time, please contact us for confirmation. Grab another battery for when the waves keep pumping and you've got a little more to give! Paddle or motor back to the beach, grab a sip of water, refresh the zink, plug a fresh battery in and get back out there for round 2. The battery is purpose designed, built, and tested especially for the Foil Drive Assist system. Every battery has been carefully manufactured and extensively tested in house, featuring a built-in Battery Management System (BMS) to ensure safety. The BMS manages the charge rate, balance of the individual cells, low and high voltage cutoff, internal resistance and temperature monitoring. Each spare battery is shipped at storage voltage.
