This is component side of the mystery device I think it is a temp sensor. The device is on a 4s3p LifePO4 18650 pack in a 5 module stack.it has no connection with the BMS's 3 per module. the positive and negative wire look to be 24 awg. The cells are 1500mAh full river 18650 LiFePO4

Just near the glue (glue's probably just holding the wires), it does say "bat temp"
Anything readable on the chips that might help?

Thank you , it look me 5 minutes to see bat temp even after you said it was there, it is as I suspected a temp sensor. I will see if I can take a better pic of the chips. There looks to be printing on the chips but when I try to focus on the printing it becomes a blurry black mess.
Later floyd
