2、11.1V, 14.8V或更高 ? You should check your ESC s allowed voltage input, which you get from the speed control s manual. 你应该在你的电调使用说明中看看你的电调所允许的输入电压。What does 12C, 15C, and 20C mean? 12C, 15C, 和 20C是什么意思呢? The “ C” rating is the amp draw of the battery. It relates to discharge limits of the LiPo battery.

3、 That means they are capable of taking higher discharge loads. A higher C rating gives the user the feel of more power or punch when accelerating. C数值指的是电池放出的电量，它与LIPO 电池的放电限制有关。高的C值那意味着该电池具有高的放电负荷能力；同时，高的 C值也給使用者在加速时有一种更具爆发力的感觉。What is the difference between two cells and three cells? 2芯和 3芯的电池有什么区

4、别? A 2-cell LiPo battery has the same relative voltage as a 6-cell NiMh or NiCad type battery that is 7.4 volts. 2芯的 LIPO 电池具有跟 6芯的镍氢 ,镍铬电池相似的电压 7.4V。Running a 3-cell LiPo battery will give you the relative equivalent voltage as running 9 to 10 NiMh or NiCad cells. Be sure that your speed control is

5、 capable of running this higher voltage or damage may occur. 使用一个 3芯的电池能給你一个9到10芯镍氢或镍铬电池带来的电压。请确保你的电调能承受这么高的电压，否则会有产生损伤。Electric motors are capable of running different amounts of voltage. However, more voltage can and most likely will generate more heat in the motor. You will get much higher speeds

6、, but you are starting to push the limits of the motors. 电动马达能在不同的电压下运行。然而， 高的电压往往会产生更多的热能，你也能得到更高的速度，但其实你在挑战马达的极限。It is important that you pay attention to gearing; incorrect gearing along with prolonged runs using high-capacity batteries can result in excessive heat, causing it to swell and possib

7、ly catch on fire or explode. 所以， 应该注意你的传动系统，用不对的齿轮组合长时间在高电压电池的环境下奔跑会导致过度的热量，从而很可能导致膨胀，着火甚至爆炸。This will overheat the ESC itself and damage it and possibly overheat the motor as well. 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 2 页，共 8 页 - - - - - - - - - - 3 - Thes

8、e possibilities are not strictly limited to three-cell LiPos. 这会使电调本身过热而受损，马达也一样。而这些可能性并不局限于3芯LIPO 电池。What do the numbers on the battery mean? Like 1250, 2000, 2850mAh, 2S2P, and 2S3P. 电池上面的数字是什么意思? 像1250, 2000, 2850MAH, 2S2P 和 2S3P. 1250, 2000, 2850 are battery capacity numbers in milliamps. The hi

9、gher the capacity number, the more run time the battery will have. 1250, 2000, 2850 是电池以毫安为单位的容量。高的容量值意味着更长的使用时间。A 2S2P will be 2 cells in parallel (this is how you get a 7.4 volt battery with 2000 millamps). 2S2P的意思指 2个电芯并联 (这是如何使你的电池达到7.4V并带有 2000MAH 的容量的方法)。The “ 2S” means there are two cells in

10、series (to get the 7.4 volts) and the “ 2P” means two in parallel to get more capacity. 其中的 2S表示 2个电芯串联 (来达到 7.4V)，而 2P则指 2个电芯并联从而达到更高的容量。Adding another cell in P will be 2S3P and would raise the capacity. 再加上一个电芯并联则会再次提高电池的容量。Wired in parallel means that like polarizations are connected (positive t

11、o positive, negative to negative). 并联指电芯两级各自相连。(正连正，负连负) Wired in series means the opposite - positive is connected to negative. 串联则反之 正极与负极相连。Inside the LiPo pack are not your familiar cylindrical cells. LiPo “ cells” are about a quarter of an inch thick, about the same width and length as the pack

12、age itself, and stacked atop each other. 在LIPO 电池组里的电芯并不象我们熟悉的圆柱形电芯，LIPO 的电芯是约 1/4英寸厚， 并由长 ,宽是与电池组本身相当的电芯相互叠加而成的。I see batteries on the market and some say TX or RX even though they may have the same specifications. 我看到市场上有些我看到市场上有些电池说电池说 TX 或RX 尽管他们有相同的参数说明尽管他们有相同的参数说明。TX (transmitter) and RX (rece

13、iver) batteries are different in size, have different mAh requirements, and different voltages. TX( 发射器 ) 和 RX( 接收器 )的电池是尺寸不一样，并有不同的容量需求,和不同的电压要求的。Typically, an RX 2-cell LiPo battery is 7.4 volts with mAh (millampere hours) from 1100 to 1800 or more. 一般地说， RX电池是 2芯， 7.4V ， 1100-1800MAH 或更高容量的电池。A T

14、X battery has up to 11.1 volts - it s important that you NEVER plug a 11.1 volt battery into your 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 3 页，共 8 页 - - - - - - - - - - 4 - RX or it will damage the circuitry of the receiver. 而TX 电池则是 11.1V 重要的是，你不可以放11.1V 的电池在你

15、的接收器上，否则会损坏你的接收器。Also there are receivers on the market that are not compatible with the 7.4 volt batteries, so a voltage regulator must be used to reduce the voltage level so it won t damage the receiver itself. A typical RX has a 6.0 volt maximum. 当然 , 市场上有些接收器不能适用于7.4V 的电池，所以，为了不损坏接收器，就必须使用电压调节器了

16、，一般的接收器最多接受6V 的电压。Do I need to “ balance ” my LiPo batteries? 我需要 ” 平衡 ” 我的 LIPO 电池吗 ? Your LiPo battery pack will have either a balancing port or a connector, and you should either purchase an optional balancer like the Astro Blinky and/or a charger that is has the capability of balancing LiPo batt

17、eries. 你的 LIPO 会有一个平衡的平台或者是一个平衡充接口，你需要买一个像ASTRO BLINKY平衡器或者一个具有平衡LIPO 电池功能的充电器。If the battery goes out of balance (or match), they have a higher chance of failure since the packs are sensitive to overcharging and discharging. 如果你的电池里的电芯相互不平衡(或者不匹配 )，他们就会很可能用不了。因为这样的电池会容易过充过放。Many people who have LiP

18、os claim that they do not use a balancer because it takes too much extra time and is not worth the trouble. 很多拥有 LIPO 电池的人声称他们不用平衡器因为他需要太多额外的时间，而这样不值得。For safety s sake, it is worth the trouble! 但 , 出于安全 , 平衡你的 LIPO 电芯 , 值得 ! A balancer keeps the voltage in your cells equal, which helps to keep the

19、battery from over discharging or overcharging. 平衡器能使你LIPO 的电芯之间的电压相互相等，这样能帮助保护你的电池过充过放。This is very important especially when charging and overcharging a cell causes it to spontaneously swell and possibly explode. A balancer will reduce this risk factor. 这是非常重要的，特别是当你充电时，过充一个电芯就很可能引起它的自然鼓胀，也可能爆炸。平衡器

20、就可以降低这样的风险。However, as with anything LiPo, human error is the most common cause for LiPos exploding. So take caution and read the manufacturer s instructions before charging. 然而然而， ，像所有的 LIPO 一样一样， ，认为的错误是电池爆炸最普遍的原因认为的错误是电池爆炸最普遍的原因。所以所以， ，请在充电前注意请在充电前注意， 并仔细阅读生产商的说明仔细阅读生产商的说明。 。Is a voltage limiter

21、needed in LiPo applications? 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 4 页，共 8 页 - - - - - - - - - - 5 - 在 LIPO 应用中应用中， ，电压限制器需要吗电压限制器需要吗？ ？The limiter is actually a voltage cut-off specific to LiPos used with older speed controls that are not LiPo 限制器实际上是与老款电调一

22、起使用的对LIPO 的一个电压自动切断的功能组件，它并不是 LIPO 。Compatible and with receivers when using LiPo receiver batteries. It is to prevent the battery from being discharged too low during use, which would make the pack unusable. 当使用 LIPO 接收电池的时候也可与接收器兼容的。它是用来阻止 电池在放电时在使用中过放而使电池不能再用。The cutoff is usually around 6.25 vol

23、ts or 3.0 volts per cell. Once a LiPo discharges below 3.0 volts per cell, there is less chance that you will get it to recharge again. 电池的断 路电压 通常是 6.25V 或3.0V 每片 电芯， 只要LIPO 的单 片电芯电压低于3.0V ，你就很可能不能再对其充电了。Do 3 cells take more time to maintain? 3芯电池需要更多的时间来保养吗? It does not take more time - it takes m

24、ore care! The maintenance is the same for any LiPo batteries, but common sense is your greatest tool. 它不是需要更多的时间，而是需要更多的小心 。它的保 养 和一般的 LIPO 电池是一样的。但常识才是你最 好的工具。Unfortunately, people who do not take care and follow the rules set by the battery manufacturer are to blame for LiPo-related disasters due

25、to incompetence. 很遗憾 ，因为 误使用 LIPO ，而产生相关的灾难 ，惨剧通 常是 追责 于那些不注意和不遵从电池 厂商设定 的的使用 规则的人。Examples of improperly treated batteries include: running their motors until it s 80 degrees centigrade, overheating batteries, overcharging with the incorrect charger settings, and over-discharging the battery. 不正确使用

26、电池的例子 有：在80度的高 温下仍然运行他们的马达，使电池过热； 在不正确的充电设置 下过充和对电池的过度放电。Lithium Polymer Safety Tips 锂聚电池的安全提示: Lithium Polymer cells are a tremendous advance in battery technology for RC use. However, due to the chemistry of lithium cells, there is a possibility of fire if charging is not done properly! LIPO 电芯是为

27、RC所用的一个极为先进 的电池 技术 。然而，由于 LIPO 的化学 成分 ，如果充电不当，电池有可能着火。Care is unavoidable due to the nature of lithium itself. 所以，由于 锂电的这个本 质天 性， 小心 是不可 避免 的，是必须的。名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 5 页，共 8 页 - - - - - - - - - - 6 - This is no different from many things w

28、e use in daily life knives, kitchen cleaners, and automobiles, for example which are inherently dangerous, but which can be used safely by adhering to simple rules and precautions. 这像我们生 活中用的许多 东西 一样 比如说 刀，厨房清洁 用具， 汽车 等。他们 都 是天生危险的，但只要 遵从一些指示适当使用，就不会有问题 。? Be absolutely sure that the Lithium Polymer

29、 charger settings are correct for the battery pack being charged both voltage and current settings. 在电池充电时，绝对要确保 LIPO 充电器的 设定 是正确的。 电压和电 流的充电 都应该是 设定 正确。?
