DC-DC Step Up Down Boost Buck Voltage Converter Module LM2577S LM2596S
If you have a battery that needs a stable voltage output, then this module fits your requirements best. This module keeps your desired voltage even with the lower or higher input voltage. You would need at least 4V up to 35V input voltage for this module to work. The output is controllable using a potentiometer from 1.25V to 25V. It also has screw holes so that mounting won’t be a problem. The combination of LM2596S (Step-up converter) and LM2577S (Step-down converter) makes this a one of a kind Buck-Boost Converter module.

- Make sure of the voltage and current of the battery you need to charge.
- Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage.
- Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease).
- Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected charging current value
- The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
- Connected to the battery and try to charging (for previous 5 steps, module input terminal is connected to power source, output load is NOT connected to batteries)
