Please tell me more of this 'heat transfer coefficient' and how to calculate it. I imagine it involves things like the dimensions of the box, the materials used etc.?
Thinking of driving my Tec1-12706 at about 4 volts to act as the heat barrier but might be able to go lower I guess. Will have to experiment.

leaseYou shouldn’t have to reinvent the wheel. The data sheet for the TEC should give you the current versus voltage and the delta-T versus current information. For the current, a TEC resembles a resistor as long as you’re above about 1.5V.
The number I’d be looking for is the heat transfer coefficient of your box. Measuring that will allow you to relate the cooling load to your battery capacity.
