Screws are a very popular tool of joinery and fixing of items. Unlike nails, screws can be used in many different surfaces; they can be used on wood, metal, concrete and even steel. Driving these screws on wood is not a daunting task since, all one needs is a manual screwdriver or an ordinary mechanical drill driver and the screw is firmly inside the piece of wood. However, when it comes to driving screws in metal, concrete and steel, one needs a powerful drill driver. These types of drill drivers are not common but Bosch Corporation has one, Bosch GSR 10.8 V-LI, a cordless lithium ion driver.

A: In general, it's a good idea to fully charge your cell phone battery the first time you use it. Then, allow it to completely drain to zero before you charge it again. If you do this three times it will help to condition the battery to give you a full charge. This is particularly important for NiMH batteries but is also relevant for cobalt ontario copyright-Ion batteries as well.

Japanese automaker, Mitsubishi, on the other hand, confirmed that its i-MieV (Mitsubishi Innovative Electric Vehicle) electric car will be presented to US market before 2012. A single charge of its lithium ion batterty stocks-ion batteries will take i-MieV up to 100 miles. Mitsubishi plans to produce 20,000 i-MieVs a year if its partner GS Yuasa can keep up with the demand for lithium-ion electric car batteries. There is no official word on how much Mitsubishi's electric car will cost but it is expected to be around $30,000. Little pricey, huh?

Only charge your battery when it needs it. After a full charge, use as much of it's capacity as you can before giving it another charge or swap in a spare battery. Also don't use the charger as a radio stand and leave your fully charged battery in cobalt ontario copyright there for repeated extended periods of time. This will shorten your battery life.

Charge your batteries in an open well ventilated area. If a battery does become unstable you want the hazardous fumes and material to be vented from the room.

In other parts of the world, however, they haven't been so lucky. Europeans have been experiencing gas prices between $5-$8 per gallon for years. But they still get around. Common among their usual transport is a bicycle. You've seen many pictures of common folks getting around town bicycling. Kinda like what we did when we were kids. To get more "mileage", a lot of Asians and Europeans use hybrid electric motor bikes.

One final consideration with RC gas planes converted to electric. You always need to factor in cooling of the battery pack and esc. In fact many modelers, including myself, put the ESC on the outside of the plane, usually I mount it under the engine on the firewall. You also need to make air vents to cool the battery inside the model. Without this, you run the risk of overheating batteries and ESC's.
