WillyB (Johnnyjames ?) - Here's an 'apples and oranges' comparison for you - Chezzy's tests were on aaa cells, which are acknowledged to be unsuitable for anything much lower than 3ohm. Your test and mine were with aa cells.There's a big difference between the two re. behaviour under higher loads.
Our tests -
You used a pack with what looks like an odd cell - have you checked that they are all actually good? I vaguely remember someone making a similar post to yours some time ago, and it turned out that a dodgy cell was causing the poor under load results.
I used 1 year old eneloops, straight off the Sanyo smart charger, in my crappy old baccy tin mod. I drained them slightly, as I said, so the relevant no-load figure was 5.76v, 0.26v above yours, leaving an adjusted difference between our loaded figures of 1.16v. I really can't see a difference of that size being due to my 0.4ohm lighter load (That was just the coil I was using at the time btw, in my 18650 mod).
I could run the test again with a 2ohm coil, but a)I haven't got enough invested in the issue to want to , and b) there are so many permutations of cell size and quality , test rig quality, atty resistance etc. that it'd be pointless in an exchange like this.
My simple non-expert test was just an annoyed response to seeing that picture of yours yet again, and was posted to counter the immediate impression that your glaring 3.72v photo gives. You seem to have the need to dampen every nimh thread with it, despite the fact that all the limitations of nimh use have been openly acknowledged and discussed at length by the form's enthusiasts. So, are you on a mission?
