Partial screenshot of an AliExpress product listing, showing an item "LIGHTWEIGHT 4500Psi 300Bar 30Mpa 0.3L 300cc Carbon Fiber Cylinder High Pressure Tank HPPA Cylinder for Diving Scuba M18*1.5", for the low, low price of C$179.68. Buying a safety-critical item like this from an unregulated, overseas marketplace is an exceedingly dangerous and stupid thing to do.
Please, I beg you, do not buy pressure vessels from AliExpress sellers. Particularly not ones you strap to your body.
4500 psi COPV tank from some random guy who may have got it out of the "failed safety test" dumpster behind the factory...
