The description states that there is temperature protection, but the wiring diagram does not show wiring for a thermister. How is the temperature protection wired?

A:

There are two pads on the back labeled "NTC" which means "negative temperature coefficient". I suspect by wiring a NTC thermistor there you will get temperature protection.

A:

You can add as many cells in parallel as you want, BUT THEY NEED TO BE CLOSELY MATCHED BY CAPACITY AND INTERNAL RESISTANCE. This is extremely important to protect the parallel cells.
