Ion Battery

How much energy can be obtained from a lithium-ion batteries in a short period of time?
is dangerous to run a whole 20 minutes instead of hours and drain the battery very quickly. In addition, the amount of energy available to do? I saw you can get 150 watt hours per kilogram for lithium-ion batteries, but if I had, for example, 2 kg of the battery, you can run something for half an hour to drain the battery or near it all, so I'm really 600 watts during these 30 minutes?
It depends on the chemistry of the battery and the model real drums. typical laptop battery can not be good for a rate of C 2 or 3. The C-rate is a ratio of the amount of current being drawn compared to the capacity of the battery. If you have 2.3 hours on average lithium-amps, which means that you can get safely from 4.6 to 6.9 amps it before having security problems, overheating and damage to the battery. Newest chemistry and construction of batteries A123, Nanophosphate lithium iron used in the exercises 36 volt DeWalt cordless is very promising. Its technical States that can provide security 70 constant amps, and a short burst of up to 120 amps. The circuit Battery Management prevents you from using the full potential of these packages drill wireless, but if you can get your hands on the cells and create a package, can be very close to what you ask. One of these cells may bring about 4.6 amps for half an hour at 3.3 volts, and weighs 70 grams. It's an energy 15.2 Watt-hours, and you would need 40 of these cells in a packet provide 600 watts of half an hour. This package should weigh 2.8 kg before any container or wiring. Looking back on the spelling of it, unless you Package for double or triple their time in power, in regular batteries ensure that the flow would be. I tend to work more with vehicles electric, and the costs for those who tend to be much higher peak acceleration and hills of the nominal value. Lithium polymer could give a little more energy per unit weight.
Obama in the factory battery Michigan: "We see the results, President Barack Obama has used the pioneer of a lithium-ion factory today as proof that his administration bet $ 5,000,000,000 for the manufacture of electric vehicles helps to stimulate the economy. President's visit is a stop on the national promotion of the development administration of electric vehicles this week.
