Good stuff, thanks. I'll certainly keep for reference though I am hoping for a
simple solution that works with V-Reg (i.e. trickle) unless I can locate an
ASIC that does the fancy stuff with variable loads. (?)

My application consists of two parallel banks of 5 cells each (single "A"
NiMH pulls, probably from older Laptop packs or similar) for 6 VDC {at} 6 AH (yes,
each cell is rated 3.5AH so I'm assuming I can get at least 3 AH each).

I have a Timex Diehard (flashlight that plugs into AC and kicks on
automatically when power fails or when it's pulled out for use) that used
rechargeable NiCds originally. I replaced them with two of these
"A" NiMH cells
a year ago and it's working great still. Circuit seems to be a simple trickle
charger using V-Reg  ... no heat issues to date.

Be well    :^)
