Well Old, I must say, thank you again for this review. I have seen a review based on the non-protected version and it got glowing reports. But they did not test it as you have done here. Which is vitally important as most people seem to have single cell lights. I can only imagine there may be a lot of unhappy people out there who have bought the various different versions of these cells. If I read your graph right, my solarforce XML draws 2A and will not work below 3v, Therefore these could be the worst cells possible. They may even struggle in my BC 40, as that seems to cut off at around 5.5v.

Marc, i have just done full runs on my XinTD C8 to cutoff voltage and the Sanyo's recorded 54minutes vs 76minutes from my unprotected Panasonic3100. The test is not completely fair as i used the Sanyos with no cooling vs the panasonic with fan cooling. I will do the Sanyo run again with cooling. Edit: test complete, Sanyo with cooling = 55minutes on same cell, so pretty much no difference, Panasonics run considerably longer even at 2.8A draw of the C8
Both fully charged on the same Xtar charger, confirmed with fluke voltage measurment. I have a couple of protected Pannys on order for DX so ill test these also if they arrive this year...
Yes that is a big difference! Are your Sanyo's un-protected? I know it doesn't make any difference, I just wondered. Thanks for this info, very useful.
Marc.
