How to connect 3.7v lipo battery with 3 wires to a charger that only has positive and negative

Hi Guys,

Please could you advise me on this. I have a 3.7v lipo battery which has 3 cables red, black and green.

So the red would be positive. Black would be negative. And green would temperature sensor (I think).

My question is how can I connect the 3 wire battery to a two terminal charger so that it still uses the cut of temperate feature (means of the green cable) of the battery when charging so that the battery wont over heat ?

You can't ! You need a bms to monitor the temp and cut the power when needed.
