Keep your home and garage safe in case of a battery malfunction.  These cases also make it easy to ship batteries safely.  You cannot check, carry-on, or ship lithium eFoil batteries on commercial aircraft. They need to be shipped as hazardous goods on freight aircraft only. 

The rugged Zarges case provides compliance to IMDG, IATA, FAA and 49CFR requirements for safe storage and transportation of Lithium batteries. Zarges fire-resistant cases also carry UN HazMat Certification and protection against dust, moisture, extreme temperatures, corrosion, and cracks.  

These are a great way to store you batteries and transport them between sessions to protect your batteries and safe guard against fire.  Keep your batteries stored in a Zarges case always for extra protection.  The single and double case outside dimensions are the same but the 3 battery case is much larger.
