HB 25.2V 5Ah 21700 Ternary Lithium Battery
Overview&Features
Lithium polymer battery, or more correctly lithium-ion polymer battery is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity semisolid (gel) polymers form this electrolyte. These batteries provide higher specific energy than other lithium battery types and are used in applications where weight is a critical feature, such as mobile devices, radio-controlled aircraft and some electric vehicles.
LiPo cells provide manufacturers with compelling advantages. They can easily produce batteries of almost any desired shape. For example, the space and weight requirements of mobile devices and notebook computers can be met. They also have a low self-discharge rate, which is about 5% per month.
Hoppt product’s safety performance is comfirmed to
- UL1642 standard.No leakage, capacity Recovery rate:³ 90% (storage 3h)
- No explode, no fire, no leakage.
- Avoid insolation or dropping into fire.
- Avoid shorting the battery.
- Avoid excessive physical shock or vibration.
- Don’t disassemble or deform the battery.
- Don’t immerse in water.
- Don’t use the battery mixed with other model or manufacturer batteries.
- Battery charge should be used appropriate charger.
