3s smoked brushed ESC, is lipo still ok to use?

[Analyst]

Hi, I have a brushed futaba ESC that was barely rated for 2s (but got away with 4s before). I plugged in a new 3s today and within 15 seconds heard a pop, saw a spark, and the esc let out the magic smoke. Is the battery still ok to use? I’m positive there was no reverse polarity and it has not puffed, but I want to be cautious because lipo.
Thanks in advance!

Check the voltage of the cells but it should be fine

Thanks guys! I’m just looking for the same voltage across the board right?

The same or within a tenth or so.
