Hi folks. I was on a site looking at power supplies and noticed these huge MagLite-like hosts that are relatively cheap. There's a 6-D version! At almost 20" long, not terribly practical, but it will run forever and a massive heatsink in that head could accommodate several modules. Might be a good test-bed.

128 LED 6 "D" Cell Flashlight-MPJA, Inc.

The nice thing about this 6-D model is if you're looking to use the massive protected "D-cell" LiPos, you can fit 5 of them almost perfectly in here. 6 D-cells @ 60mm ea. = 360mm. 5 32650s @ 71mm ea. = 355mm.

Of course, 5 3.7v cells will mean 18.5v and an interesting driver arrangement. But there could be some specific circumstances that warrant this. Any comments on this?

There's a 4-D version if 6 is too big:

100 LED 4 "D" Cell Flashlight-MPJA, Inc.

One additional point: 6 1.2v NiMH cells is 7.2v, which is a huge beefy supply very close to the 7.4v of 2 LiPos.
