I want to put externals in a build that has a  3.7 v and when fully charged it is 4.2. Do I use 3- 1.5v alkalines and feed it 4.5 volts? or will this hurt it. I figure 2 would only be 3v and drag it down defeating the purpose of externals.

Yup, 3 alkalines will do it like Ken said. Charles had sent me some 3 AA holders but I use a reg. 4 AA battery holder and put in 3 AA's and in the 4th put one of the dummy AA's they have, these have the 9v connector type on the top and my external wires I hook up with the corresponding connector so can just snap it on (just plastic with connections on both ends so makes contact but no voltage). Use this on my externals for W30 (3.7v).
