JinDong has provided hospitals, doctors and nurses with mobile medical intelligent hardware products, application software products and mobile clinical solutions for many years. The newly developed mobile doctor workstation needs to develop the 19.2V40AH LiFePO4 battery. 

After discussed with JinDong several times, we summarized the requirements of the 19.2V40Ah LiFePO4 battery as follows,

1）Over-charge voltage：   3.9V/cell

2）Over-charge release voltage: 3.6V/cell

3）Over-discharge voltage：    2.2V/cell

4）Over-discharge release voltage：2.7V/cell

5）Normal working current：    16A

6）Over-current(discharging)：      30A

7）Normal charging current：    12A

8）Over-current(charging)：    20A

9）Over-temperature：        65℃

10）With short circuit protection

11）Balancing current：       50mA

12）Self discharge current：     working mode<2050μΑ，sleep mode<800μΑ

13）Two terminals for charging/discharging, with RS485 protocol

And the battery structure is designed as follows,

The batteries works fine at JinDong since July,2018.
