The lantern battery comes in at a close second. The 9 V battery trails the rest of the group with a mere two hours of run time. If compactness is of paramount importance, two 9 V batteries can be connected in parallel to power a drone for 4-5 h. If compactness is not an issue, 6 V lead-acid motorcycle batteries can be employed. Batteries in the 11-14 A h capacity range are readily available. These batteries are a bit heavy (they do contain lead after all). If you are looking to plant a drone in the bushes and trees outside your target’s offices, these rechargeable batteries might be a good choice. Similarly, a drone hidden inside a car in the parking lot (car park for the Brits) with a fully charged battery can be operated for over a week, given a typical 60 Ah car battery capacity. NiMH batteries can be used provided you are willing to use five AA, C, or D cells versus four alkaline cells. There is no harm in using five alkaline cells. Rechargeable 9 V and 6 V lantern batteries are also available. The 6 V lantern rechargeables are often lead acid. Table 5.3 provides typical capacities and run times for rechargeable batteries. From the table, you can immediately see that rechargeable D cells are the only option if you want to run a drone for more than a day.

102 CHAPTER 5 Powering The Deck SOLAR POWER Solar power can be used to provide all required electricity for an exterior drone or to extend the run time. Either way, a rechargeable battery will be needed to run the drone during the dark hours. Solar cell packages outputting 6 V are readily available. Adafruit offers 6 V solar panels delivering 330, 530, 600, and 930 mA (http://www.adafruit. com/category/67). In terms of size, these panels range from 5.44.4 to 8.626.87 in. Even if you are performing penetration tests in Alaska, sunlight will not be available at all times. For our calculations, we will assume sunlight is available 40% of the time and a 5000 mA h 6 V rechargeable battery is used. After a little algebra, the run time is simply equal to (battery capacity)/((average current required)–(sunlight percentage) (solar panel current output)). Negative run times indicate that the drone can be run indefinitely. Run times are shown in Table 5.4 for each of the four solar panels sold by Adafruit. MATH IS FUN Calculating Solar Run Times Generally speaking, the run time (t) is equal to the available current capacity (s) divided by the average rate of current flow (r): t ¼ s=r Solar power adds the complication that the current capacity increases when the solar panels are converting sunlight into electricity. As a result, s is no longer a simple constant but a value that depends on the run time t. Calling this new value s 0 , the percentage of sunlight p, and the current capacity of the solar panel c: s 0 ¼ s + pct Substituting into our original formula for t: t ¼ s 0 =r ¼ ðs + pctÞ=r Rearranging to get all terms involving t on the same side of the equation: Dividing by (1–pc/r): tð1 pc=rÞ¼s=r t ¼ ðs=rÞ= ð1 pc=rÞ Multiplying the right-hand side by r/r to simplify: t ¼ s= ðr pcÞ Table 5.4 Run Times For Solar Powered Drones With 40% Sunlight and 5 A h Storage Battery Solar Panel Output (mA) Run Time at 220 mA (h) Run Time at 280 mA (h) 330 57 34 530 625 74 600 Indefinite 125 930 Indefinite Indefinite
