Well I have a neutral white Mini AA which I have so far been using on Ni-mh cells, I measured 1.25a from a 4.2v cell, quickly dropping to around 1.2a and then leveling off at around 1.15a on a 3.9v and below cell.
This is over the recommended input current for an XP-E, and as they were originally only rated for 700mah and have very small thermal mass I thought this would be a big issue and should stop me using it in that set-up.
However, it recently occured to me that the iTP A2/A1 series use the same circuit, yet RCR123 and therefore 14500 are officially supported, even with the XP-E emitter. These should have been seeing the same drive currents, so does that mean it should be ok to use long-term as long as I manage the heat?
