I recently got back into RC and the Lipo batteries worried me some. I am used to the old nicad or nimh batteries that never really had to worry about. I got this along with a bundle of individual fireproof bags (small rectangle ones) to store them all in. I didn't want to just dump all my batteries in one big container as I was worried if one went they would all go! I could get about 6 of the small ones in this bag for storage and since they are all separated I am not so worried. The bag itself is great for charging batteries as the side flap is super convenient to open and put the charger leads through. I totally recommend getting some cheap insurance/peace of mind on not setting you house on fire with this especially when used in conjunction with the other bags.
