Bloated cell extreme heat when trying to equilize

[AntronX]

Roast my setup

A little dusty but looks good to me! /s

did you connect a 3.2 volt cell to your 2.6 cell to equalize it?
If so it's hot because it's getting like 1000 amps into it or something..

This.
It probably equated to something like 100C charge rate and totally cooked the cell.

I'm really surprised nobody mentioned it at all. His first post seems to say that's exactly what he did

Post number 3 "A dead cell that is paralleled with a fully charged cell is going to create a high current flow that indeed would heat up your terminals."

I have some nicer looking systems on the property. But they all work good, so no reason to post about there.

Now im gonna order 4 of these batteries to replace and have spare.

Thanks for the help

Need to cycle the battery to verify that cell pair is reasonably in balance so as to not have the BMS cut power unexpectedly.
Otherwise looks good for a temporary patch.

Bought yellow one since 2016, no any issue.
