From Sam Culper: Good Chart of Rules for the Use of Burner Phones
This one was forwarded to me by a faithful reader with the comment: "Useful information for those of us that still think that all long term battery technology involves lead plates and acid electrolytes. If you plan on humping comm. radios, using "hobby" security drones, or other high energy draw items you need to learn about LiPo batteries. They have some real advantages, but they can cause trouble, too."
