If you are like me and fly a lot, you also charge your batteries often. Safety is a priority, but no matter what, I get distracted. I work in my attached garage so if anything happened while charging a LiPo, I would be in big trouble. The LiPo Locker is a wonderful addition to my charging station and covers my tail in many ways. I use a multi-cable from RC Accessory so I have all my female plugs inside the locker along with a balance lead. I simply make the connection and drop the battery into the locker. The top of the locker is filled with sand and is held back with a layer of plastic wrap. Should a fire ignite, the plastic burns through and the sand drops to smother the fire. Great idea!
