Lithium ion Protection Circuits
Lithium ion cells have an operating
voltage range from 2.8v absolute minimum to 4.2V absolute maximum.
Charging the cells beyond 4.2V will cause them to heat up and ultimately
explode and ignite. Discharging a cell below 2.8v will damage the
cell rendering it useless. A protection circuit is essential to
keep the cells in balance and ensure proper charging and discharging.
These circuits are suitable for
hobbyists wanting to use Lithium polymer and Lithium ion cells.
We do not accept liability/responsibility for the safety of operation
of these circuits and suggest that when charging check the voltage
balance and heating of any cells frequently during the charging
period.

Lithium Ion Chargers
A lithium ion cell operates in the voltage
range min 2.8V to 4.2V Max per cell. This means you need a 4.2V
charger to charge a single cell properly to full voltage. Two cells
in series will need an 8.4V charger, 3 cells will need a 12.6V charger
and 4 cells ,16.8V.
Applying a voltage significant
higher than the required voltage will activate the protection circuit
prematurely and it will shut down the charge before the cell reaches
full charge.
We have the following Lithium
ion chargers
Our range of chargers show a red led while charging and
changes to green when fully charged. We also build lithium ion packs according to your spec -
