Product Description
The Safety Circuit is usually attached to the battery as a separate module and is commonly referred to as the PCM (Protection Circuit Module). The purpose of a PCM on rechargeable lithium ion and lithium polymer batteries is twofold.
If you have any questions, please feel free to contact me.
Lithium ion and lithium polymer batteries require a PCM to prevent explosion of these otherwise possibly hazardous technology batteries. The PCM will make the battery open circuit in the event of a wrongful condition arising such as short circuit.
For long useful service life and maintenance of maximum useable capacity the PCM is incorporated into single cells as well as multiple cell batteries in either series, parallel or a series/parallel combination. Lithium Ion and Polymer batteries will lose capacity and cycle life if overcharged, overdischarged or too high a charge or discharge current is asked of these battery chemistries.
