Li-Ion Battery Charger LCM423

Callisto Electronics Ltd. has designed a flexible charger module for Li-Ion battery packs with 1-4 cells whereas charging voltage and current can be easily adjusted. The LCM423 is an universal and compact Li-Ion charger module with a sophisticated charging algorithm for Li-Ion battery packs of 1 – 4 cells in series and a charging current of up to 2A with a DC input voltage.

These modules and finished chargers can be adopted to a wide range of requirements (module size, charging current, number of cells per pack, different temperature sensors, housing size, colour, etc.). 

A simple mains power charger is now available, please refer to the specification below.

Please find below a summary of the different models currently available. The model number provides a link to the full datasheet.
