Interfacing Lithium battries


#1

Hi All,

Does any one have idea how to interface lithium-ion battries with wavecom modules. The module provides the charging, but what are the RC values to be connected externally and whether any other circuit is also required or not.

My application requires the module to be connected to an external power source and in case of powerfailure, battery backup should be provided.

Thanks,
Abhijit
