Hi guys,
I want to build a 12V pack from 3s or 4s 18650 cells. I want to use the pack for my telescope and mount.
What I don't know is what voltage stabilizer to use. From my undestanding the step-up/step-down dc-dc buck converter changes the output voltage if the imput voltage changes. I'm correct? I would like more or less 12v constant.
I was thinking using this: https://www.ebay.com/itm/DC-DC-5-32V-to-12V-3A-Automatic-Voltage-Stabilizer-Power-Converter-Regulator/122873907605?hash=item1c9bdb0995:g:aAQAAOSwmRFafRGO:rk:12f:0
What do you recommend?
