Can I use a constant voltage and constant current LED driver to charge ...

Same applies to the constant current power supply. It will push constant current into battery until battery voltage rises high enough so the supply can''t output constant current any more. But at this point the voltage will be the max output voltage, e.g. 12V, which will be way too much for a 1S or 2S pack. And the constant …

Using a Switching Power Supply for Battery Charging

Constant current charging is a way to charge common batteries. This is a charging method where batteries are charged with a constant current from beginning to end. A standard switching power supply is a constant voltage power supply, so it monitors fluctuations in output voltages, inputs the results in the control circuit, and …

Battery Charging Stages & Battery Charging Procedure

There are three main stages to charging a battery: constant current, constant voltage, and float charge. Constant current charging is when the charger supplies a set amount of current to the battery, regardless of the voltage. This stage is used to overcome any internal resistance in the battery so that it can be charged as quickly as possible.
