That dip at the start might be due to temperature (The cell need to heat up a bit, to get full performance), my testing lab does not have a tightly controlled temperature, it will vary a few degrees.
Thats plausible. Thanks for enlightening me. :)
Thank you for conducting your tests and sharing your findings.
Thanks very much! Frontpage’d and Sticky’d.
Where can I get these batteries??

HKJ, will these fit in the TN30 & TN31? Thanks.
Any known fav lights that these positively won’t fit in? I know Hi-Max’s won’t fit in 501Bs, but I’ve not seen too many batteries that are so big that they don’t work in most lights.
The diameter is to large, but they do fit in length.
I would expect there are many light, but I have not tested.
Distributor On CNY Holiday 
I think fasttech has them in stock though. I ordered a set a week and half ago and just got them. Got another set coming in.
Again. I. Advance I apologize but if I had to pick between the keeppower black 3400 maH protected or these Panasonic 3400 maH protected which is a better performer?
I have these Batteries, they are a tight fit, but they fit both the TN30 and TN31.
Keeppower, without a doubt
i thought keeppower also use panasonic cell.
so the protection circuit does the difference?
Yup. Better PCB has lower internal resistance, and therefore less voltage drop.
I guess the clear PVC concept pays off.

just ordered myself a pair of panasonic 18650 just like in the review but with 3100 mAH.
little bit regret however the price spread between the two brands can reach $5 for the same capacity.
mind to elaborate with your post of clear PVC pays off?
