Want to purchase a spare battery? The FLAUNT / Samsung Lithium-ion battery pack puts out over 560 true watt hours (range)! The pack is a 36 volt, 15.6 amp hour battery with a battery meter, that allows our customers an average of 40 miles per charge when utilizing pedal assist in normal mode. The FLAUNT battery is built with an intelligent Battery Management System (BMS), which will not allow your battery to over-charge, or fall below safe charge values, and will even power off the bike after 5 minutes of inactivity. Slide the battery into your FLAUNT Electric Bike, and the battery locks automatically, unlocking only with your specific bike key.
