AAA batteries, is a United States standards of battery, County 7th battery or Taiwan the 4th battery standard compatible. Cell is cylindrical, high 43.6 mm, ø 10.1 mm. Is a common cell, smaller than a AA battery. Commonly used in small, not too high power consumption electronic products such as MP3 players, mini remote control and so on. Disposable alkaline batteries or rechargeable nickel-metal hydride and lithium-ion batteries.
Technical standards
Batteries can be divided into: 1, 2, 3, 5, 7th, 5th, and 7th are especially common.
So-called AA batteries is the 5th battery, and is the 7th battery AAA battery! AA, AAA is description battery type.
Dimensions
AA is what we usually call the 5th battery, General dimensions: diameter: 14mm, 49mm;
AAA is what we usually call the 7th battery, General dimensions: diameter: 11mm, 44mm.

Lithium battery selection considerations
1, lithium battery type and capacity options.
First according to their power of motor (needs real power, cycling speed will correspond to a corresponding actual power) to calculate the required current for the battery. Motor continuous current of 20A (48v 1000W motor), that requires batteries to 20A currents and temperature is very low for a long time (even if it's 35 degrees outside in summer temperature, battery temperature is best controlled at below 50 degrees). If a 48v 20A current overpressure 1 time (96v, ecpu 3) continuous current up to 50A. If you like pressure for a long time, then please use the sustained current of 50A battery (also, note that temperature rise).
26650 Rechargeable Li-ion Battery current is not the business of the nominal battery capacity. Businesses rated c (or more shijibai AMPS) battery discharge capacity, and really in this to decentralize power, heating is very serious, if not heat, battery life will be short. (And our environment is from the battery electric vehicle battery cluster emissions, leaving no gaps, tight-lipped, let alone how to do forced air cooling). We use a very tough environment. Battery discharge current use with Derating. Evaluation of battery discharge current capacity, is to see the current battery temperature is. Here the principle is actually used only during discussed battery temperature (heat is the battery life of arch-rivals)
The best battery temperature is below 50 degrees. (20-30 degrees is best). This also means that if it is a high capacity lithium batteries (control in the 0.5C, the devolution of power), the capacity is above 40ah 20A continuous discharge current required (of course the most important thing is to see the battery internal resistance). If it is a power type lithium battery in accordance with 1C continuous discharge is normal. A123 ultra low on-resistance power type lithium battery, is usually best in 1C discharge (less than 2C as well, 2C discharge is actually only half an hour out of power, not much use). Capacity depends on car storage space size, personal spending budget, expects car activity range size, and other factors. (Small volumes generally have power type lithium battery)

High power current powered lithium battery protection board and the difficulty
With the development of Community energy more and more scarce, the emergence of new energy is even more impatient, lithium battery new energy is one of the more important new energy, along with lithium-ion batteries 26650 Battery protection box also followed the emergence of new energy emerged, he was born out of security concerns.
Lithium battery protection board, characterized, it is used for maintenance of lithium-ion batteries do not damage and prolong the life of the battery. And it is only in the case of lithium-ion battery pole questions make the most stable and the most useful maintenance to avoid accidents. Usually no action, of course, monitor homework is necessary, just like our household appliances sound or sound switch in the same.
I want to say is to protect the balance function of the Board, there was talk of using lithium battery protection board with equilibrium must be functional. Personally think that protection board is protected, it only in the most extreme of the battery play an effective role in protection, it does not have the ability to raise the battery performance, the protection plate just a passive part. 2~10A, for example lithium batteries are generally current, which we can do no more than 200mA. So say lithium-ion batteries are the most important, we should try to improve the consistency of the battery. Strengthening the matching operation.

What is Eco-friendly Ceramic Knives？
Eco-friendly Ceramic Knives with precision ceramic developed by, so called ceramic knives.
Ceramic cutting tool wear resistance, high density and high hardness, no pores, not filth, non-metal casting will not rust, cut food no residual metallic taste, thin and sharp and easy to handle and easy to cut, easy to clean ... ... Advantages and has many characteristics of metal tools cannot replace.
The hardness of the ceramic knife is 9, second only to the world's hardest diamond, the substance of (10), if used without falling to the ground, without external impact, going to chop or cut down, permanently under normal conditions of use do not require sharpening.
Based on security considerations, manufacturers are generally mixed with metal powder in the body, so that metal detectors can detect ceramic knives.
Ceramic knife is not suitable for cooking need to chop, chop the food, in addition to bones, raw fish ... ... Other hard ingredients not suitable for use with ceramic knives other than food, such as frozen meat, vegetables, bamboo shoots, fruit pulp, raw fish (without case), meat, seafood, soft shell shellfish ... ... Rigid non-food use.
Traditional metal cast business of tool, for its surface has countless hair fine hole, so cuisine food material Shi will has soup juice residues Yu hair fine hole in the, and cuisine food material Shi metal business of tool will has trace of metal, formed odor or metal taste; and ceramic knife of density quite high, so surface no hair fine hole and ceramic material development, not has odor or metal taste.
But ceramic knives are high quality consumer goods, in the ordinary man is a Virgin and inaccessible. The hardness of the ceramic knife is very high, but it is as fragile as glass, so use with caution. It is more than 10 times times the sharpness of kitchen knives, very sharp, to avoid the kids.
