Figure 1. Most lithium batteries with three connections have an internal NTC thermistor When using NTC thermistor, it should be connected between THM pin and ground (connected via BAT). A resistor (R7) is also connected between the THM pin and the reference voltage (VL), which creates a voltage divider.
Integrating NTC thermistors into battery packs is crucial to ensure their safety and performance. By continuously monitoring temperature, NTC thermistors allow for proactive measures to be taken in case of abnormal conditions.
I use the battery with a fuel gauge (lc709203f on a module designed by adafruit). So it would be very simple to interface with that thermistor. hold the cell between hands. if you feel cold then hand surface lose a warmth toward the cell. Conclusion: insulation is very weak.
When using NTC thermistor, it should be connected between THM pin and ground (connected via BAT). A resistor (R7) is also connected between the THM pin and the reference voltage (VL), which creates a voltage divider. Choose the value of the resistor so that it has the same value as the NTC thermistor at a temperature of +25°C.
We use a thermistor in a voltage divider circuit to determine the temperature of an external module such as a battery pack. A thermistor is a variable resistor whose resistance varies in proportion to the temperature that the thermistor is exposed to. There are 2 types of thermistors- NTC and PTC.
The short version is that you can solder a 2k through-hole resistor into the holes marked PROG to set the charger to its maximum current level of 1A. To use a thermistor, remove the surface-mount resistor in the footprint marked THERM and solder the leads to the thermistor into the corresponding holes.

In battery packs, NTC thermistors play a crucial role in monitoring and regulating the temperature of the batteries. By accurately measuring the temperature, NTC thermistors allow the battery management system (BMS) to make informed …
Battery pack thermistor | Electronics Forums
I''m rebuilding a 14.4v and 18v Milwaukee battery pack and need to replace the thermistor. I could read 6K8J on it. I understand this to be 6800ohm 5%. It was a small disc about 1/4" in diameter with two leads. It must be NTC because when my body heat is applied the resistance drops. It seems that most battery packs are cut off at 70°c

Looking to replace my headphone 3.7v LiPo battery. Do I need
I want to have a longer battery life in my headphones, and took it apart to see how replaceable the battery is. I found a 600mAh battery and figured I could easily replace that with this 1100mAh one from Amazon. Only issue is I noticed a third wire, which on the board is labelled NTC which I gather is a high temp cutoff. My two questions are:
Pinout for LiON Rechargeable Battery | All About Circuits
I would like to use the battery pack as a module and take advantage of the existing charger and and even the built-in protection features. ... I would say the battery is A_E, and the thermistor sensor is A-C, charger is probably C-E, ... It does not connect to pin C which has a voltage on it.

Ensuring EV battery safety with advanced temperature monitoring
The battery cells can still overheat due to physical damage, manufacturing defects, or overcharging. Therefore, temperature monitoring of lithium-ion battery packs is a critical safety function. Detecting temperature rises early in a battery pack minimizes the risk of a cell entering an uncontrolled thermal runaway and igniting a dangerous fire.

$begingroup$ Sometimes I have opened up a battery pack, and found one of these thin film resistors. I can imagine that ideally you want that termistor in the middle of the batteries, and if the thermistor don''t have direct contact with a battery, account for the temperature delay. $endgroup$ –
How can I replace 3 wire lipo battery with 2 wire or 6 wire battery
Aliexpress have the correct replacement battery however shipping costs are crazy. I doubt the Asus Nexus battery will fit, in any case its not available. The thermistor will be a standard 10kohm one but if its not integral to the pack it might as well be a 10k resistor as it won''t detect thermal runaway soon enough to act in shutting the charge off.
