Hi All,
Got it finished
Using 2ea 14500 in series and a 5v regulator. Input to the regulator with fresh batteries is 8.39v and output from the regulator is 4.98v. Credit for the RCA goes to Warp, not sure who suggested the regulator from TI, but thanks to them also.
Here are some pictures.
Thanks for looking
