3-pins on battery. What are they?


Recommended Posts

I am reviving a begode battery that was deeply discharged

While there isn't any obvious balancing leads for the 24 cells, I'm curious about the 3+1 output pins. What are they? I'm measuring some voltage on all of them. Some threads suggested they are +,- and a temperature sensor of some sort, but the wire gauge, despite being a little smaller than the other 2, seems to suggest otherwise.

Anyone has an insight on this? I believe the pack comes from a Begode Hero.

100.8V, 450Wh, 24S, LG M50LT

On the connector, 2 leads are black, one with a thicker wire gauge, the third is red matching the thicker gauge. A 4th white wire is on a seperate white 2-pins connector.

ThanksĀ
