High density 2S rechargeable 18650 26650 7.4V lithium ion battery 4500mah for smart lock

Description of Lithium ion(lii-ion)  Battery
There are many advantages to using  li-ion battery. These li-ion battery advantages include:

High energy density: The much greater energy density is one of the chief advantages of a lithium ion battery or cell. With 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.

Low Self-discharge:  lithium ion battery is that their rate of self-discharge is much lower than that of other rechargeable cells such as Ni-Cad and NiMH forms.

No requirement 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.

Low maintenance:rlithium ion battery  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.

Variety of types available:  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.

The capacity and dimension can customize according to your request.
