Need to ship lithium-ion batteries by ground or sea? CellBlock FCS battery cases provide a safe, reliable, and compliant way to send batteries from point A to point B. In the event of a thermal runaway, our battery storage and transportation cases don’t just contain battery fires; they completely suppress them with the help of our proprietary dry fire extinguishing media, CellBlockEX. Shipping batteries and devices containing them has never been easier. Ship damaged, defective, recalled (DDR) and prototype batteries with our UN approved and DOT Special Permit solutions.
