NiMH or Lithium?

I did look at 3v7 LiPo batteries(the ones in the silver bag) with a boost controller etc, but I agree with you - it adds an extra level of complexity, and one thing I did build that used them(foal alerts for horsies), they would fail for no apparent reason, and then the unit would not work, so I went back to 9v NiMH for that project too - never had a problem since. @ Godoh - yes, it does get chilly here in winter.  Zero or less most nights.  Might stick with the NiMH batteries then.
