*Flex tolerant does NOT mean fully flexible. These packs are designed to handle the inevitable micro-flexing and vibrations that all electric skateboards will experience. If your deck and enclosure system is meant to flex a significant amount (segmented enclosure, Boosted-style deck, etc.) then please check out our other battery offerings.
