Please help, I am trying to build a circuit that uses either 2 AAA Li batteries (4.5 A and 3.1 volts) or 4 AA (5.0 Volts and 8.0 amps) for a circuit to run a peltier chip with requirements of 0.5-1 volt and 1.5 amps. I am very new to electronics and have been trying to create this simple circuit with no luck. Any ideas including changing the power supply would be welcome, but is must be free standing
Thanks
to add further detail, I am trying to develop a device for biomedical research that is small ~50-75grams that is able to cool a biological sample about 0.5 Watt (415cal/hr?). The battery can be changed at regular intervals if required so if I can get an hour of work from a battery that would be great. The circuit will be controlled via a PMC with a thermocouple input for temperature measurement. The PMC will also communicate with a computer via RF for data collection.
the peltier is from custom thermoelectric part#00711-5L31-03CA I max 3.0 A,Qmax 1.4 Watt,Vmax 0.9 Volts
