You can easily recharge batteries if you have a DC power supply. All that is needed to recharge battery cells is DC current. With DC current, electrons will flow back into the battery, establishing the electric potential, or voltage, that a battery was meant to have when it's fully charged.
There's a lot of DIYs that utilize DC/DC converters to charge Lithium batteries. A quick Youtube search shows dozens of these DIYs. I was wondering how these home-made chargers work. Yes, DC/DC converters do provide constant voltage and constant current, but the mechanism of battery chargers isn't exactly the same?
All that is needed to recharge battery cells is DC current. With DC current, electrons will flow back into the battery, establishing the electric potential, or voltage, that a battery was meant to have when it's fully charged. A DC Power Supply is needed that allows for adjustable voltage and current.
The most appropriate method for charging batteries among them is with a power supply that has constant current voltage drooping type characteristics (Far Left) where a constant current range is used for charging batteries with a constant current. The other two characteristics should not be used to charge batteries.
Normally a lithium battery charger starts with a constant current supply to the battery and then as the battery reaches its full charge voltage, the charger detects the battery's voltage and adjusts the current until the battery's voltage stabilizes.

For example: Let's say we have a 10s 10 Ah Li-ion battery pack with a nominal voltage of 37 V and full charge voltage of 42 V. Now, charging this pack using DC/DC converter that could supply constant voltage of 42 V and let's assume we charge the battery at 0.2C which means 2 amps.
