4pcs Lipo Battery Fireproof Explosion Proof Bag Storage Guard Safe Pouch 185mm…

Perfect size and great for storing cash inside a safe as an extra layer of fireproofing. I bought these and the Turnigy name brand of the same size and would guess they're made side-by-side in the same factory. Same build quality as the name brand, though these are possibly, almost imperceptibly a little thinner. Still, they provide piece of mind, so I returned the Turnigy ones.

Only way to get thru inspection at the airport. I just take them out of my bag and place them in the tray. Never a question.

Perfect for storing and transporting my drone batteries. Depending on your battery size, you can store up to 2 of them in the same bag and still prevent the contacts from touching. Bags are made of thick material. The fold over flaps and partial wrap around closure should hold up to battery explosion if it occurs. The velcro closure holds well, yet isn't a struggle to get opened. Should these bags protect my drones, other batteries or other equipment from a damaged battery, or protect my batteries from something, then they are definitely worth the cost. Lastly, if you've traveled by air with your drones, then you know the rules of them being in your carry on and how they have to be transported. Not only is it easier to use these, it's safer too. Merely wrapping the contacts does nothing good to isolate a battery to prevent damage to it. I've flown twice with my batteries in these Lipo bags and haven't had an issue.

The case is nice, and helps organize different battery types with one in each case, but the case is a little floppy. I solved this by cutting a piece of cardboard the size of the case, and putting it inside, to make it more rigid. Much easier to use now.

Anyone who uses Li-Po batteries for robotics, RC cars/boats/planes/drones, etc., is well aware of the dangers associated with improperly storing, using and charging them. I use a lot of 18650 batteries in various AI drone projects. The thing I like most about the bags is each one can hold about 25 18650 batteries. The bags appear to be well made. I haven't had an incident with a battery overheating but I'm confident that the bags will meet expectations.

As described

These LiPo battery safety bags are a smart purchase for anyone who charges or stores LiPo batteries. Getting a 4-pack gives you multiple options for different battery sizes and the fireproof material gives real peace of mind. They seal up well and are a simple way to store batteries more safely when not in use. Essential safety gear for RC and drone hobbyists.

Haven’t had a battery blowup yet, but I’m glad I have this. It makes transporting batteries safer.

Perfect

Nice size for my use case, decent quality and good value for money - you will need to work out the creasing from them coming flat packed, but once you have done this they hold their shape well.

Perfect for the intended purpose. Use them for RC car batteries.

This bag has a good wide Velcro band that securely locks the bag closed if you need to use it. All drone Pilots should have some of these with your safety flight kit. They are well worth the money if you have a Lipo battery smoulder and catch fire.

Exactly as expected, great quality lipo charging bags and an absolute bargain!
