Low temperature LI battery

Theres starting to come to the market a few ‘value branded’ LiFePO4 12v 100amp batteries, one that I’m aware of that has a ten year limited warranty...My guess is that the individual cells are merely generic and bought in bulk from some unknown supplier with unknown quality specs....So, who can really say the true origin or the uniform methods specified for each individual cell, or the final assembly or of the BMS, and how should one expect a little known vendor to still be around in say 10 years time??

In my view, paying a little more money for a major reputable brand name is moola well spent...
