I'm looking to build an expensive portable battery system for outdooring, backup for power outages etc. And won't the best grade & matched cells as it makes no sense spending 1000's on the system then cheaping out on the battery. The CATL 202 & 271 look very attractive because of their high wh/kg.
But I have no experience buying anything like lfp cells from aliexpress & alibaba etc. I can't find these from a reputable distributor by the looks.
Here is what I found from the green store:
Don't these seem quite cheap? Has anyone had success getting grade A well matched through these stores?
There is some confusion for me, according to the evlithium website page they seem to say these cells are rated to 3500cycles to 80% at 1C charge/discharge with their 12V battery, the datasheet for the 202 on this forums says 0.5C, yet on the aliexpress page specs it seems to say they are rated at just 0.2C, does this sound right? 0.2C seems quite low, I think many other brands are 0.3-0.4C.
Basically need hep finding the best cells I can get. thanks
