This is the ProTek R/C "Flak Jacket" Flame Resistant Lithium Polymer Charging Bag. LiPo sacks are required at most tracks, and are highly recommended for all LiPo applications due to the associated risks. When your table space is limited, the last thing you want is a bulky item taking up space. Plus, the size of most 2S - 4S LiPo packs doesn't justify using a large bag. Once again, ProTek R/C has you covered with a smaller, more convenient solution developed specifically for surface applications and smaller flight packs. Because less intrusive gear means more work space!
The ProTek R/C "Flak Jacket" is a conveniently sized bag that should be used when charging and storing your LiPo batteries. Its small 160x65x70mm footprint (16x6.5x7cm) will fit just about anywhere and is the perfect compliment to most 2S - 4S hardcase and softcase packs, as well as smaller flight packs. The space age materials and thick, industrial strength hook and loop fastener will help to reduce the severity of a LiPo battery fire, while the attached strap will allow you to move the battery to a safe place if a problem should occur.
NOTE: Due to the volatile nature of Lithium chemistry batteries, charging bags such as the ProTek Lithium Polymer Flame Resistant Storage Bag are required by many tracks, flight clubs and at ROAR sanctioned events.

the lining begins to unstitched after 10 uses
not sure about the security ...
maybe an unsafe safety bag...
Sorry Amain...this protek item is a loser for what your charging and after it tore I looked at it closely and my guess is that had I had a battery fire when charging in that bag the material is half as thick as the two other brands I own and I really have my doubts that it would have even slowed the fire down from spreading at all. Poor quality material should never tore when opening it and big doubts if it would contain a lipo fire in a real world fire.
I find it hard to believe a product of this nature wouldn't be more robust, with at least double stitching all the way though with thicker trimming etc..I have just contacted amain about it and I am sure they will help me out, I just hope they change the design of the product, after all it is made to protect people and property.
Will update when I hear back from them, but for the moment I cannot recommend this product.
