Lithium Battery charge Monitor

 

Lithium Ion battery is now used in many devices. Unlike other batteries, in Lithium Ion battery, the charge level is expressed as percentage. Its minimum voltage is 3.6 V and maximum voltage is 4.2 V. It is the fully charged state. You can Monitor the charging of 18560 Lithium Ion battery using this circuit.

Automatic Battery Charger

Here is an efficient battery charger for Car battery and Inverter battery. It quick charges the battery with 5 Ampere current and cut off charging when the battery attains 13.8 V which is the full charge condition of the Lead Acid battery. Red LED indicates charging process while Green LED indicates full charge and charger cut off status.

How to make a Mini Power Bank

Don’t throw away the old Mobile battery. The high efficiency Lithium Ion battery can be reused to make a Mini Power bank useful as a Travel Mobile charger. For this, you needs a Lithium battery charger Module and a Mobile charger module in addition to the battery. Both modules will cost around Rs.100.

How to determine the voltage level in Lithium Ion battery

Lithium Ion batteries are now widely used in Mobile phones, Power banks, Digital cameras and other devices that requires 3.6 V . Lithium Ion batteries are long lasting since its current rating is very high above 2300 mAh.It is very important to maintain Lithium Ion batteries since, both over charging and poor charging may completely destroy the battery.Some have the habit of plugging the Mobile phone in charger overnight. Mobile battery needs to be charged only when its charge goes below 50 %.Proper charging and discharging increases the life of Mobile battery and its efficiency. Let us see its voltage levels

How to Convert SMPS to Bench Power supply cum charger

Don’t throw away the SMPS power supply when the Computer damges. SMPS is a high current device that gives different regulated voltages from the output wires. It has numerous wires to give different voltages . So you can make a good Multi voltage power supply for the Projects or use as battery charger for different types of batteries. It has total isolation from Mains and output is safe DC.
