The BLD-72V-IP68-ESB series is a purpose-built lithium-ion battery pack for performance-grade electric surfboards operating in open-water environments. Available in two configurations \u2014 72V 50Ah (3,600Wh) and 72V 58Ah (4,176Wh) \u2014 both packs are built on 26650 cylindrical NCM cells and deliver sustained 200A discharge output to support 10\u201315kW motor systems without thermal throttling or voltage sag under full load.<\/p>\n

The IP68-rated enclosure is tested for continuous submersion at 20 meters, with dual-layer silicone gaskets, pressure-sealed T-handle, and a magnetic switch that functions reliably in saltwater without corrosion. The 26650 NCM cell format is selected specifically for its higher energy density over 18650 at equivalent discharge rates \u2014 a requirement for compact marine enclosures where volume is fixed but runtime expectations are high.<\/p>\n
