Electric help. Solder circuit. 3 questions. Need help with a thermistor that keeps burning out ?

[Steven Noyb]

Tldr: replacing thermistor, how to do it? Which is a better replacement for 2.5d-13? And what is the name of the plug in the second link?


Bought an ebike scooter.
Needed off board charging, the guy at the shop rigged something for me.
The battery is 72v45ah battery
The charger is a 6amp charger.
Anyways I'm going to replace the thermistor.
It's a mf-2.5d-13 thermistor
Specs are as follows:
2.5 6 0.088 13 60
Res ohms 2.5
Max steady state current 6

R. Of max current 0.088
Dissi.coef 13
Thermal time constant s 60

Here are some pictures of the battery with red connectors.

My issue is it'll probably burn out again. 3 quick questions.

1. Is there a better thermistor that can be used that will be more durable less likely to burn out?

2. When I get it I know where to solder it. I was just going to put it in the same position and same orientation. Is that enough? Is there any tips or warning I should know of?

3. What plug is this:

Yeah you don't want to mess with that.
Even using the rigged thing is dangerous, but if the thermistor is the only thing that keeps the battery from exploding before it gets too hot then you definitely want that to burn out instead of your battery catching fire.

And why is the battery getting hot?

Circumstances, when, etc,,,,

Do you let the battery cool before recharging it?
