Frequently asked questions
Can I use it as a battery charger?
Yes. The module can be used as a battery charger, and it has LED indicators that show the charging process and when the battery is fully charged. Set the output voltage and current limit to match your battery before connecting it.
What input voltage does it need?
The input range is 4 to 32 VDC. Because it is a step-down converter, the input voltage must be higher than the output voltage you set.
