Hibernium® battery packs are equipped with Mann + Hummel Burst vent (XTCSM002841) pressure compensating vents.
In an event of battery pack failure these vents provide a critical safety function, allowing expanding gases to escape the pack.
It is recommended to install diffusion plate near breathable vents to protect personnel in this situation.
Vent needs to be protected from impacts during installation. Damaged vent invalidates ingress protection of the battery and need to be immediately replaced.
