Q:Why does a battery discharge time be shorted?


Normally the battery internal resistance will be increased with more use, then the battery discharge performance will be degraded, and voltage drops more fast, so the discharge time be shorted.

Q:What is the difference between parallel and series circuits?


Parallel circuit is involved two or more batteries connected to extend the capacity. In this case, the positive terminals are connected together, and the negative terminals are connected together until the desired capacity reached.

Series circuit connects two or more batteries together to increase the voltage. We connect the positive terminal to the negative one until reaching the voltage we need.


Q:What are the advantages of lithium batteries?


High Energy Density:Electronic equipment such as mobile phones needing to operate longer between charges while still consuming more power, there is always a need to batteries with a much higher energy density. In addition to this, there are many power applications from power tools to electric vehicles. The much higher power density offered by lithium ion batteries is a distinct advantage. Electric vehicles also need a battery technology that has a high energy density.

Self-Discharge:Lithium ion cells is that their rate of self-discharge is much lower than that of other rechargeable cells such as Ni-Cad and NiMH forms. It is typically around 5% in the first 4 hours after being charged but then falls to around 1 or 2% per month.

Low Maintenance:One major lithium ion battery advantage is that they do not require and maintenance to ensure their performance. Ni-Cad cells required a periodic discharge to ensure that they did not exhibit the memory effect. As this does not affect lithium ion cells, this process or other similar maintenance procedures are not required.

No rquirement for priming:Some rechargeable cells need to be primed when they receive their first charge. There is no requirement for this with lithium ion cells and batteries.

Variety of types available:有几种类型的锂离子电池available. This advantage of lithium ion batteries can mean that the right technology can be used for the particular application needed. Some forms of lithium ion battery provide a high current density and are ideal for consumer mobile electronic equipment. Others are able to provide much higher current levels and are ideal for power tools and electric vehicles.

Q:What is the high C rate LiPO battery?


一般来说,如果在电池C倍率≥5C,那么这种电池被定义为高C速率锂聚合物电池。必威电竞赞助深圳市普瑞电池betway 体育是哪国的可以连续地排出至60℃,和200℃脉冲。更重要的是,这种电池可fast chargedvia 5C.

Q:How does a LiPo battery work at high temperatures?


The high C-rate LIPO battery provides higher discharge rate of up to 60C, and better stability, controlled within 65°C to prevent overheating and damage;



The C rate is representative of the charge and discharge capability of thelithium-ion polymer battery. The C rate is divided into a discharge rate and a charge rate, and "C" is used to indicate the ratio of the charge and discharge current of the battery, that is the rate.

For example, a 1200 mAh battery, 0.2 C means 240 mA (0.2 mA of the 1200 mAh battery), and 1 C means 1200 mA (1 times rate of the 1200 mAh battery). Normallybetway 体育是哪国的可以快速充电。

Q:Can shape batteries support fast charge?
