Can you tell me how much does it draw? What about the electronic switch? Other charasteristics and details?

I study electronics in university and I have designed my own "power box" which uses li-pol battery as a primary power source. I am interested to know how Duralite has designed the regulator unit as I have tested many combinations with succes. My device also has secondary battery pack and constantly measures both batteries to decide which one to use. It also shows me the state of the power system with two led's.
