C40 re wrapped cells resistance mismatched

Hi. This is from the seller page. I used these cells for an ebike battery, but when charging the pack (16S) the BMS was having a hard time balancing the cells. So I checked the internal resistance of each, and they ranged from 2.50 to 3.40 ohms. Could this difference in resistance be a problem?

BMS 3s 40A failed

Charged my Eve 30p in 3s7p configuration at 10A current. Charged cool, no heating at all, but by the end I checked and the BMS was now hot, so I disconnected the charger but the heat didn't go. Ended up disassembling the battery and checking each cell voltage.All is good with the cells 😭. BMS. What options are there for my pack? This cheap BMS was rated for 40A, but the MOSFETs died at 10A.

Shiny ones

Noticed that these guys were shining. It looks like their backs are full of air. They are stuck; they can't swim down.
