Can a lab power supply charge a lithium ion battery?
The purpose of this tutorial is to learn how to use your lab power supply to charge your Lithium Ion battery when you donβt have a special charger circuit. He used NCR18650B in his tutorial, a 3.6V 3400mAh Lithium Ion battery from Panasonic.
What type of battery was used in the tutorial?
He used NCR18650B, a 3.6V 3400mAh Lithium Ion battery from Panasonic, in his tutorial. The purpose of this tutorial is to learn how to use your lab power supply to charge your Lithium Ion battery when you donβt have a special charger circuit to do so.
Is a constant voltage buck converter good for battery charging?
If you have just a constant voltage buck converter all you can do is adjust the voltage. Thatβs good enough to power all kinds of cool and interesting and awesome loads, but it's not good enough for battery charging. For battery charging you have to be able to set both the voltage and the current.
What is the recommended charging method for lithium ion batteries?
Itβs better to use dedicated ICs designed for the float charging for lithium ion batteries. David said that using float charging/trickle charging is not recommended, because it will build-up or plate the metallic parts inside the battery.
How do you charge a battery with a buck converter?
For battery charging you have to be able to set both the voltage and the current. With a good constant current buck converter, you'll be able to do that easily. This one has buttons on it so you can literally just key in the voltage and current that you want.

$begingroup$ @Coriolanus A fuse at the battery ensures that shorted wires anywhere, including shorts in the power supply or other malfunctions - such as shorted pass element in the supply - will blow the fuse and cause no further damage. A diode will dissipate more than a fuse, and it increases the output impedance of the supply.
