HOBBYMATE Lipo Safe Bag Fireproof, Lipo Safe Bag for Lipo Battery Storage and Charging, Lipo Battery Transporting Bag with Double Zipper (260x130x150mm)

Finally, a quality safety bag for charging my Li-po and li-on batteries. I understand the volatile nature of the chemistry which is the makeup of these batteries. The volitality is basic knowledge, undervoltage from over-discharging, overvoltage from overcharging and extreme temps from mismatched motors and battery packs. I'm very critical of my equipment when charging these types of batteries and I use well known charging devices and kepmthe firmware updated, no matter how diligent I am the charger being an electronic device failure can happen at any given moment beyond my control so I am never 100% trusting of the charger. However I do enjoy having peace at mind while charging that my batteries are in a fireproof bag should failure arise. Having used several sizes and brands they either did not hold up very long or they were advertised as fireproof but actually more flammable than the batteries that were supposed to be charged within. The Hobbymate bag appeared to be nothing of that sort based on specs so I gave this one a try. The bag is well constructed with Velcro and zippered closures, heavy stitched seams and heavy piped outer edging. The construction is the best I have seen to date and by far the most impressive. I have been charging my 3DR Solo batteries and Gens Ace 4s batteries without failure thankfully but I am at ease knowing that should a reaction occur I would be able to remove the bag and get it outside to extinguish without damage to my home. This goes without saying I hope to never have to test the fire ratings on the bags, I am prepared should it happen though. After using the bag for a month, I have decided to purchase two more to store my batteries in while not in use. One more thing...I took my drone on 2 separate flights with my batteries in this bag and had them charged a t a storage rate. I placed the bag on the belt at the STA security check prior to my flight and explained the contents 3 out of the 4 agents commented on the quality of the bag and 2 stated this should be the safety standard. Please note that yes this was only 2 trips but both were round trip. The one that did not comment didn't need to as he looked it over carefully and smiled and gave me a nod of approval. This was worth the purchase price 10 fold. The pricing is competitive with other inferior products and could fetch a higher price and frankly I would pay it without question. If you use these types of safety products give Hobbymate a shot at your business, hopefully you will be as impressed as me. I don't write too many reviews but if it's worth noting to others to keep them from wading through all of the junk out there, I'm happy to do so. Happy flying!

If you have enough batteries to need a larger bag for storage and transportation, this may be your solution. It appears well made and solid. Access is provided via dual zippers + velcro on front flap which more than adequately secures the content at the cost of being a tiny bit fiddly to open and close. The material is a little thinner than I expected for a bag of this size, but should be more than sufficient. I store my batteries in their original boxes whenever possible and with the bag filled to capacity this way, the weight is easily supported. If filled to the brim with just batteries it would be a bit heavy, but I suspect the bag would support it without problems. Due to its size it seems to be be better suited for storage and transportation than for use during charging, but it can be used In either capacity. I had just run out of room in the 2 medium size Lipo safe bags that I have, and this one is perfect for storing the bulk of my battery stash, thereby freeing up my two midsize ones to take to the field. If you're pretty into the hobby and have lots of batteries, you'll most likely find this to be a very handy addition. I have nothing negative to say about the bag at all. The only thing I can't vouch for at this time is durability, but it appears up to the task it's designed for. If you carry your batteries around "naked" be careful of sharp edges and take precautions to keep anything from shorting the battery leads unless you're really keen to test the bag's ability to suppress and contain fires and explosions.

Truly love this fireproof bag, feels way thicker and is a lot higher quality than i expected. Really durable feeling double layer construction, all the seams and stitching are very sturdy feeling and everything locks up tight. Inside this thing can easily hold over Twenty (20) 4s 1300mah lipo batteries comfortably, also depending on how tightly packed you want it, it could hold another 10+ batteries. The double zippers really close up tight, but still allow you to make as big an opening as you need to fit your cables through. The velcro on this thing is TOUGH STUFF, really really grippy and does a fine job holding together, takes a lot more effort than you would normally have to use to pry them apart. Very fine construction of that alone. Oxygen gets locked out easily with this fireproof bag and put my test flame right out, i can say this thing would definitely help if a lipo fire ever happened. I wish it came in a different color, but im sure it has something to do with heat and the material, i dont have any negatives about this bag at all actually, its high quality, has a low price, and does what its supposed to do. I will continue using and testing this fireproof bag and will update this review if need be, other than that id highly suggest picking one up, just a GREAT product overrall.

Well made and definitely inspires some confidence when storing/transporting my batteries. Before having this I would keep them in a metal toolbox, but I was always worried that if one of my batteries went the box would blow apart and end up causing more damage. We never use our fireplace so that has become my "charging station" recently. After all, it was built to contain fire. I keep this bag and my chargers in the fireplace now and don't worry about anything. It has a zipper that zips from each corner so you can still poke the balance leads out and keep it zipped and it has velcro in the front just in case. The velcro is very good and takes some effort to open. The material of the bag is very thick. I have 3, 3000+ mah batteries and 2 1500 mah batteries in there and there's plenty of room for more. 4 stars, only because I haven't had anything happen and don't know how well it will hold up. I'm confident that, with the way its constructed, it will be fine, but I hope I never have to find out.

As any RC hobbyist knows, safe battery charging practices are a must. With today's Lithium based batteries, it is even more important than ever that we take care not to overcharge, over discharge, or mistreat our batteries. The threat of LiPo batteries bursting into flames is very real, and is not meant to be taken lightly. I'm pretty sure many of us know someone, or have a friend that knows someone that has experienced a household, or garage fire due to a LiPo battery bursting into flames. Many times this is not even due to misuse, or bad charging practices. It can happen at any given time. Therefore, it has become important to find ways to charge more safely, and with a little added protection in the event that the worst does happen. Most of us nowadays have begun using what we call LiPo safes, or LiPo charging bags. I use LiPo bags not just for charging my batteries in, but I also store my batteries in LiPo safe bags. It simply gives me a little peace of mind knowing that if something does happen to go wrong, the fire should be contained to the bag, and not spread to the rest of my garage/house etc. My biggest issue with the LiPo bags I was using was that they just didn't seem to close securely when charging in them. They would seal up just fine as long as there were no wires going into the bag, but during charging, I just wasn't happy with a simple velcro closure. Well... HOBBYMATE to the rescue! :) As soon as I saw their new bag with its double zipper closure, accompanied by the traditional velcro flap, I knew I had to have one. This is by far the best storage, and charging bag I have owned. The double zippers allow me to position the wires coming from my charger in ways that the bag is still very securely sealed no matter which way I have the wires coming in, and with the zippers, and the velcro flap I feel very confident that I have little to worry about in the event of a fire. Check this bag out for yourself if your looking for a good size bag, with plenty of storage capacity. As you can see in one of my pics, there is room for a large variety of battery types. In the one picture I have a 4800mah 2s, and 5000mah 2s car/truck batteries, three 3s quadcopter batteries, and a 4s quadcopter battery, and I have only covered the bottom of the bag. It will easily hold 4 times that many packs. I personally try to keep a few packs in a few different bags, so if one goes up in flames, I still have some batteries in another bag.

Hopefully it never sees a fire but it seems good quality and strong. Zipper is a must!

Good stitching and the zipper & handle seem good too. Nice medium sized bag all around, no complaints at all. These smaller battery bags by Derblue are a great companion to this Hobbymate and 2 to 4 of these smaller bags fit inside the Hobbymate perfectly and add an additional layer of protection. DerBlue 2pcs Fireproof Explosionproof Lipo Battery Safe Bag Lipo Battery Guard Safe Bag（185x75x60mm） This Hobbymate battery bag not only has a zipper, it has a large velcro strip all the way across the front to make sure the lid stays closed if a battery ever exploded inside it. This Hobbymate battery bag will hold several MJX Bugs 2 batteries.

Good fire protection for lithium batteries.
