Certainly. The thermistor is just a simple type of fuse. When you draw too much current through them, they heat up slightly and cut out, just like a mechanical switch. After a few minutes, they cool off and start conducting electricity again. Hasbro puts them in flywheel blasters specifically to prevent us from increasing the voltage and the current. Darn them 🤬

I've noticed different blasters use different thermistors. Some are bigger, some are smaller, and some are more tolerant than others. I first discovered this when I was modding a Hail-Fire that just wouldn't take two IMRs. The thermistor would cut out after just a few seconds. But I've also had a couple XD Stryfes that could take 3 IMRs without tripping the thermistor. So clearly there are some differences in the types, sizes, and ratings of thermistors they're using.

If you're doing batteries, I recommend removing them altogether. The simplest way is to give them a three quarter twist so the bare metal legs of the thermistor are touching each other. That essentially bypasses them. Alternatively, you can just cut them out with a wire cutter and splice the supply leads back together. Either way is just as effective.
