Camera - a fragile thing, prone to all sorts of harmful influences. If you want it served cobalt properties for a long time then pay attention to the mechanical structure. If the shell metal, then at least not crack if dropped. There are models designed to operate in extreme conditions. Traditionally Pentax pays great attention to protect their equipment from the adverse effects of the environment.
In the RC boats sale, you'll find models in a wide array of sizes. The smaller ones can be just a few inches in length, while the bigger ones can be positively gargantuan reaching up to several feet. The choice will depend on how and where you plan to use the boat. A little one will be fast and easy to carry lithium facts around but may not perform well on rough waters. A bigger, heavier one will need a powerful engine and will be difficult to move from place to place but it can handle a bit of turbulence much better. Most tournaments place restrictions on the weight and dimensions of entries so read up if you plan on joining any of them.
The last thing to start tinkering on is the rate of fire. The biggest thing that will determine your ROF is the battery voltage and the amount Milliampere-Hour rating (mAH). Some of the best batteries for increasing ROF are the LiPoly batteries (Lithium Polymer) but you should not use these types on out of the box guns. When preparing to use the Lipoly battery you need to make your internal components are reinforced and upgraded where they need to be.
You lithium bettery stock do not need all the sounds. Using heavy mp3 ring tones, keypad tones, vibrating and other chimes together are unnecessary. If you want a ring tone, switch off your vibrating mode. If you are using vibration then turn off mp3 ringtones. Turn down the overall volume of your phone as loud mobiles can be annoying and prone to battery wastage. Remember that vibration mode drains out most of your battery power.
Briefly relating back to overall size... many lithium 18650's will differ ever so slightly in length (measured in millimeters). This is mainly due to an added protection circuit. The circuit helps to prevent the battery from over-discharging, since Li-ion cells can easily become damaged if their power is drained below a particular voltage. The protection circuit also prevents the cell from being over-CHARGED as well. These cells are very sensitive. They must be handled carefully, gently, and as described above, must never run-down too far, or be charged over and above their threshold. They can actually explode if severely mistreated!
Today, many of the latest computers have a fast recharge feature where you can recharge 90 percent of the battery power by charging it for around one hour. The balance 10 percent is recharged slowly. If your laptop has this facility, do use it. This helps to extend the life of the battery. However, do not recharge the laptop battery until it has less than 30 percent charge remaining.
