How do I charge a 12V battery from a 12V 30A power supply? Answered
This is my first post ever and I am completely new to this but would like to be able to charge a sealed lead acid battery. The battery is 12V12Ah / 20HR. Is it possible to charge directly from power supply which is 12V30A or do I need a resistor to limit current? Besides a power supply is it also possible to recharge the battery a different way? I tried online and made a circuit that didn't really output correct voltage. Can anybody please help?
