Product Description
1. Product Introduction of 48V 20AH Rechargeable Lithium Ion Battery
48V 20AH Rechargeable Lithium Ion Battery is suitable for electric bicycles with rated voltage 48V and rated power ≤ 500W. The battery pack (according to QBT 2947.3-2008 standard) is composed of 18650 cells in series and parallel connection (including protection board). The battery pack has the characteristics of green environmental protection, strong kinetic energy, high energy ratio, ultra long cycle life and safe use. Lithium-ion batteries are widely used for their light weight, high capacity and no memory - many digital devices are powered by lithium-ion batteries, although they are relatively expensive. Lithium-ion batteries have a high energy density, with a capacity 1.5 to 2 times that of nickel-metal hydride batteries of the same weight, and a very low self-discharge rate. In addition, lithium-ion batteries have little "memory effect" and do not contain toxic substances, which is an important reason why they are widely used.
Modularized design and pefectly compatible to the electric bicycles which are using traditional VRLA batteries
1) ''Green" and environment-friendly, no pollution to the environment during production and normal usage
2) Stable structure and simplified production process enables mass production and easy maintenance
3) Completely new protection design of water-proof, fire-proof, shock-resistance enable high safety
4) Professional protection module and BMS ensures the battery pack to be protected perfectly
5) High weight and measurement specific energy ensures the battery pack extremely long-voyage ability
6) Super long life supported by innovative technologies, high quality material and strict manufacturing control
