Where is the 18650 lithium battery pack?

Such as lighting fixtures, communication equipment, instrumentation, audio equipment, model aircraft, video cameras, notebook computers, digital cameras and other commonly used electronic equipment. 2. Series and parallel can be combined in series or parallel to form 18650 lithium battery packs. 3. Small internal resistance. The internal resistance of polymer batteries is smaller than that of normal liquid batteries. The internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces the self-consumption of the battery and extends the standby time of the mobile phone. , Fully able to reach the level of integration with the world. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models and has become the most anticipated product to replace Ni-MH batteries. 4. There is no recall effect. It is not necessary to empty the remaining power before charging, which is convenient to use. 5. High voltage 18650 lithium battery voltage is usually 3.6V, 3.8V and 4.2V, much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries. 6. High safety function 18650 lithium battery has high safety function, no explosion, no incineration; non-toxic, no pollution, and RoHS trademark certification; all kinds of safety functions are completed in one go, and the cycle times are more than 500 times; high temperature resistance is good, under 65 degrees The discharge efficiency reaches 100%. In order to guard against battery short-circuits, the positive and negative electrodes of the 18650 lithium battery are separated. So the short-circuit phenomenon may have been reduced to the extreme. A protection board can be installed to guard against overcharge and overdischarge of the battery, which can extend the service life of the battery. 7. Long service life The service life of 18650 lithium battery is very long, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries. 8. The capacity of a large-capacity 18650 lithium battery is usually between 1200MAH~3600MAH, and the battery capacity is usually only about 800. If the 18650 lithium battery is combined to form an 18650 lithium battery pack, the 18650 lithium battery pack is so-so and can break 5000MAH. .
