CellBlock Battery Cases

CellBlock X Large Battery Case
The CellBlock XLarge Case prevents lithium battery fires from propagating, and suppresses fires internally. Typical measurements - 51.25” x 28.25” x 24”. Shown with optional locking casters.

CellBlock Transportation and Storage Cases are a superior solution for the safe transport or storage of lithium-ion batteries and devices containing them. These cases are engineered, not just to contain a thermal event, but to completely suppress a fire. In a recent test by Underwriters Laboratories and Stress Engineering Group, the cases were proven to completely prevent propagation in Class D lithium-ion batteries. Ship by land, air, or sea with complete peace-of-mind.

Intelligent Construction
Our battery storage cases are assembled from CellBlock FCS rigid panels and CellBlockEX fire-suppressant insulation within an aluminum shell. When batteries or devices within the unit experience a thermal event, the panels insulate the outside of the box from the extreme heat, while the CellBlockEX granulate serves as both a fire extinguisher and a filter, absorbing harmful fumes.

Brilliantly Simple Deployment
When flames are present, CellBlockEX fire-suppressant media is automatically released from inside the lid and immediately works to extinguish the flame and halt propagation. After such an event, the case may be recharged for continued use.

Features and Benefits:

  • The safest box on the market for DDR batteries, devices, prototype batteries, etc.
  • Vents allow safe release of pressure pulse from an explosion
  • CellBlockEX insulation effectively uptakes smoke and gas
  • Can be manufactured in nearly any size and shape
  • Brilliantly simple implementation and deployment
