Please allow an elementary question: If I run an A1 (DB 917) on 3 R123s (with an extender) vs. 2 R123s, am I increasing output, or just runtime?

Thanks.

DB917 simply means it will put out 917 ma at any voltage up to Vin. It is regulated converter, so more voltage in simply reduces the current needed by the converter and you get longer runtime. YOu will get 917ma output with a Luxeon III whether you have 2 or 3 batteries.
