The cheapest solution for battery pack that can be discharged at a low temperature -20 degrees
Item 18650 battery Pack
The battery block can adapt to the low temperature discharge environment. -10--Minus 20 degrees Celsius still needs normal discharge.
Field use of industrial outdoor tablet computers
The product is charged indoors and outdoors when used. So only need to consider that -10--minus 20 degrees Celsius still needs to be discharged normally
Battery Pack ICR18650 11.1V 3350MAH
Single cell LG18650F1L
The cell support low temprature discharge
We can assemble the battery pack with LG18650F1L and Samsung brand lithium cell
2 Through the software board, set the charge protection temperature and discharge protection temperature flexibly.
The parameters of the protection board are shown in the following table.
When the battery charging voltage reaches 4.28V, the protection board is activated, and the battery can no longer be charged in and out, but this protection value is constant and cannot be adjusted.
When the battery voltage reaches 2.7V when the battery is discharged, the protection board is activated and the battery can no longer be discharged, but the protection value is constant and cannot be adjusted.

Discharge temperature protection
|放电时的温度保护阀值/ Discharge temperature protection||无/NO|
In order to solve this problem, we choose a smart board to increase the performance of flexibly setting charge low temperature protection and discharge low temperature protection, to set relevant parameters according to actual application requirements.
The case is as follows
When the charging temperature is at 0 degrees, it will not continue to be charged
When the discharge temperature is at -30 degrees, it cannot be discharged continuously
