Hi,
I am building a portable power supply using a 30Ah 12 volt rechargeable battery. The battery provides power to a number of devices that require 12 volts to operate and some that require 5 volts. The total drawn amperage is about 4 amps.
I have a couple of amp meters and volt meters built into the system to monitor the available power. And after a few hours the voltage drops to 11.5 volts. I want to be sure that I get steady 12 volt power to one specific piece of equipment that requires 12 volts so I have been thinking about pairing two 12 volts in series and then regulate the voltage to 12 volts. I am not able to find a high amperage voltage dc voltage regulator anywhere. I need something that can handle at least 5 amps.
Any ideas?
Thanks a lot.
