12V 110Ah battery pack for solar product I like your solar battery pack. Good quality and delivery fast.

—— Eyal Dolev

The battery pack is more atractive for us . May I receive drawing of other pack 12V 20AH with dimentional info ? I need 50pcs to test .

—— Nizamettin

We have received the battery packs and performing tests have passed . We are impressed by the assembly. it is almost the best one . thank you

—— Alexander Kozhushko

Pictures show a nice battery pack, performance is ok , We need serial connected 4cells (4S1P) configuration with protection circuitry

—— George Komisar

big thanks for your work, we got the cargos last week, it seems nice.

—— Johnny Black

I think it is a good idea to solve the problem, I am really appreciate you would like to help us.

—— Simone Kowalk

yes , we received the batteries and chargers last Friday, Everything looks great,well packed, no damage and dlivered in the time frame as promised.

The cheapest solution for battery pack that can be discharged at a low temperature -20 degrees

 

Item 18650 battery Pack

 

Design background:

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.
