ROLOWAY Lipo Battery Bag Fireproof Bag (15 x 8.5 x 10 inch), Large Lipo Bag Fireproof Battery Bag, Lipo Safe Bag with Comfortable Handle, Reflective Strip, Lipo Charging Bag

Handy bag fold flat when not in use. I put in my scooter bag til I board the plane

The pictures make it look like the bag is fairly rigid, howerer it isnt. Its quite floppy and in honesty if i was using it a lot i wohld avoid. The velcro flaps around the zip are annoying. So its the usual lipo bag quality, average thickness. It's a big size bag, I can get 2 normal lipo bags side by side (the ones that hold 2 batteries). It will easily hold 10 lipo pouches, so 20 batteries. It's good value for money, however I feel it could benefit from some internal structure to give the bag some rigidity.*UPDATE*After having this bag for a while now it is quite annoying. The flaps make it awkward to u zip and the zips themselves are quite tight. Combine this with the lack of structure around the too makes it quite frustrating to use on a frequent basis. It is a big bag and hold many lipos, it's just a shame the bags has no rigidity to it.
