Tedgix K4 B8 Pro Waterproof Battery

The Tedgix B8 Pro is the long range 808 Wh battery for the Tedgix K4 series SUP and kayak motors, the same pack offered in the upgraded K4C Cruise bundle. On the K4C it delivers about 8.75 hours of relaxed cruising, nearly double the runtime of the standard B4, so full day tours and multi stop expeditions run on a single charge.

The sealed marine grade case is built for open water in both fresh and saltwater, and the waterproof quick connect DC port clicks onto the K4 motor cable in seconds. Swapping from a drained pack to a charged one takes moments, no tools needed.

At 9.3 lbs the B8 weighs more than the 5.7 lb B4, a fair trade for paddlers who want maximum time on the water. Runtime varies with speed, rider weight, wind, and current, from roughly 2 hours at full throttle to 8 hours and more at cruising pace.

This is the battery module only. The Tedgix K4 Battery Fast Charger is sold separately. NIXY is an official distributor of Tedgix products.
