EvoLithium & HubLion = Worst battery ever ?

Hello Group,

I saw on another POST here that HubLion had a disgusting internal assembly (worthy of the first cheap batteries on Aliexpress). So, I bought a battery from the Evolithium brand with Auto-Heating and Bluetooth. Here in Quebec, it's cold, so I tested putting the battery in the freezer to test the heating system.

The problem I have, and I would like your expertise on this: When I take the battery out of the freezer, it shows -16 on Bluetooth, but 5 minutes later, by the time I get my charger and prepare, it already shows 2 degrees on Bluetooth.

I did another test today: I left the battery on the kitchen table for 4 hours, and it already showed 20 degrees. Then, I put it back in the freezer, and in 2 hours, it was already at -6.

One last important point: Batterie et Cie Store (in Quebec city) confirmed to one of their customers, who shared their experience on Facebook, that this was normal.

What do you think??

IS IT POSSIBLE THAT EvoLithium batteries don't have Temp probe on cells ? Is it a problem or it's normal ?
