Tedgix K4 B4 Waterproof Battery (423 Wh)

Tedgix K4 B4 Waterproof Battery The Tedgix B4 is the standard 423 Wh battery for the Tedgix K4 series SUP and kayak motors, the same pack that ships in the K4C Cruise bundle. On the K4C it delivers about 5 hours of relaxed cruising at 3.1 mph, or about 1.3 hours at the 6 mph top speed. Keep a charged spare in your dry bag and a quick swap doubles your time on the water. The sealed metal case carries an IP68 rating, protecting the cells against water, salt spray, and sand in both fresh and saltwater. The waterproof quick-connect DC port clicks onto the K4 motor cable in seconds, and an integrated battery management system with intelligent temperature control watches over every charge and discharge, rated for roughly 1,000 cycles. The B4 also pulls double duty off the board. Its USB-C port supports PD3.1 bidirectional fast charging, so the same pack that drives your motor can top off a phone, camera, drone, or laptop at the beach or campsite. This is the battery module only. The dedicated Tedgix charger is sold separately, and the pack also accepts USB-C PD charging. Backed by a 1-year manufacturer warranty. NIXY is an official distributor of Tedgix products.
