The Colcase Lipo Safe Bag is a pretty handy item to have out at the field. It's a nice container that stores (and arrives) in a surprisingly small form factor, but easily holds a day's worth of lipos safely for transport. Design- The lipo safe bag arrives with the sides folded in, but unfolds to a roughly 8x6x5 form factor. The case has a pretty rugged looking double zipper that gave me no issues during the duration of my testing. The whole bag has the feel of an insulated lunch sack, and offers a decent layer of insulation between you and a flaming battery without skimping on battery capacity. The handle, while an overlooked feature, adds another layer of convenience and safety by giving you something aside from the insulation to hold onto, a nice feature the manilla envelope style battery bags sorely lack. Functionality- This bag easily holds a day's worth of flying time for trainer or 1.4m warbirds. In my case, it holds 4 3s2200s, 2 4s 1400s, and 2 4s3000s without having to stack lipos on each other, so there's plenty of room to add more. In general, this is much nicer than my usual strategy of throwing a half-dozen loose, charged Lipos into the trunk and hoping to find them all again The double zipper is quite nice for charging. As charging is usually one of the more vulnerable times for lipo fires, i pull my other batteries out, put a couple of charging packs and the charge leads into the lipo safe bag, and seal it (mostly) with the double zipper, a novel design. Safety- This case has a thick layer of insulation material and a very nice zipper, keeping a raging lithium fire a good pace from your hand. Because of the zippered design, i doubt this is "Explosion proof", but it will definitely buy you critical time to get the batteries or yourself to safety. Cons- There's really not much i had issues with. I've had manilla envelope style lipo bags for a few years, but never really used them, they seemed needlessly bulky and perhaps not useless, but questionable with their velcro seal and lack of holding options. This takes up a smaller footprint in your car than the flat lipo bags, but holds quite a bit of stuff, has a better sealing mechanism in a metal zipper, and the handle on the top is a nice touch for general convenience and carrying. Conclusion- The Colcase Lipo Safe Bag fills a few roles in one package. It acts as a storage and organization system, and also as a fire safe bag. It easily holds an average day's worth of lipos in one place, in a form factor that's familiar and convenient. The double zipper is very nice and allows this to feed charging cables in while keeping a good seal around the rest of the bag. If you're looking to keep yourself, your vehicle or your workshop just a little safer from a lipo fire, and keep your batteries in one place, this is a great item to have on hand.

Safe for my lithium battery 👍

Quality bag. Two 46 Amp lithium batteries in.

Pleasantly surprised by the storage capacity of this bag; such a good value for the money! I assumed the size would be just for average e-bike batteries but it actually fit my upgraded large gas tank-shaped battery perfectly! Will be buying a second for my original battery so I can keep both my batteries inside during cold winter nights. The design is cute and the construction is solid, really nice material and seems well made. I can’t speak to it being fireproof or not (and hopefully will never have to test that) but given the amount of care they put into this creation, I will trust that it does what it says it will do. Great functional bag to have no matter what size e-bike battery you have, this will probably fit! The hole for the charging cord is super convenient, too.

I am quite happy with the Colcase Lipo Bag. First of all, it is a good sized bag for the average R/C enthusiast, such as myself. I put 26 - 2, 3 and 4 cell batteries in it and there is still room for a more. The carry strap makes it easy to hold on to while I have other things in my hands and while it is big enough for all my batteries, it is small enough the be carried with ease and not take up a lot of room in the shop or in the car. It appears to be well made from quality materials and the double zipper makes it easy to put the batteries and the charger inside while charging and then pull the zippers together up to the cord, for safe charging. I`m actually thinking about buying a few more so I can store different size batteries in their own bag and one to use just for charging. The difference between this bag and some of the others out there, like my old one, is noticeable as soon as you open the box from Amazon.
