Hello, and thank you for the quick response.
When repairing an car amplifier, sometimes is needed to regulate the current to reduce the risk
Of generating more problems.
I have a 12 volts 20 amps power supply which current can be adjusted from 3-20 amps.
What I will like is to find the way to regulate the current of a 12 volts battery the same way I do with my 20 amps
Power supply.
Thank you
