From a technical standpoint there is no difference between a lithium ion battery used in applications such as

surveying and one used in a military application. The difference is in the testing regime and the documentation.

Typical batteries for non-military applications may undergo testing such as UL2054, IEC62133, or IEEE1725, etc.,

while military batteries undergo MIL-STD 810G. Totex is experienced in testing to MIL standards as well as dealing

with FAR and DFAR clauses. Totex is also ITAR registered.
