- Most "fast charge" nicad packs use the fact that once the nicads are fully
- charged, they start heating up. In cheapo schemes the "sensor" is just a
- thermostat that opens up when the batteries start getting hot. The charger
- ckt then flips to a trickle mode.

- With these methods removal of the sensor will cause a fire or explosion
- as the charger will continue at full-tilt-boogie till.......
