Li-Ion
batteries have become safer to use over the past years and don't
show safety issues anymore, but almost all manufacturers require
an additional protection measure. This is usually achieved by adding
a small PCB assembly which provides the following protective functions:
- overcurrent/short
circuit
- overcharge
(battery will be cut off from charger if voltage exceeds certain
levels)
- overdischarge
(battery will be cut off from load if voltage drops below a certain
level)
- optional
overtemperature
Callisto electronics
Ltd. has develop a number of different modules to cover a wide range of
possible variations of single Li-Ion batteries as well as 2-4 cell Li-Ion
battery packs.
Summary

Callisto electronics Ltd. can tailor the existing
modules to your special needs, like adjusting the maximum charge/discharge
currents, delay times for the overcurrent protection, shape and
size of the module itself, etc..
