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 - Call us for quotes.
