HKJ, you must be a mind reader! I was just thinking how cool it would be to have a tool to select batteries to compare output charts and you've created one!
AWESOME!!
Thx a lot for this review and the new comparo chart, what a great service to the community!
Compared to the one benckie tested, these looks better. They have higher voltage during the 3A discharge. This might also be due to resistance in benckie's wires and magnets, the voltage difference is about 0.1 volt, only 0.03 ohm is needed for that at 3A.
With the photos I have posted benckie or anyone else that got these batteries from Manafont, can probably tell if there are any difference in the wrapping or construction.
Yeah i think my main charge leads, soldering and the rare earth magnets might make a slight diffrence, but still good for reference as 0.1 volt is not much.
Im not confindent DX will maintain sending out good cells and it might end up like the trustfire flame 18650,s they where selling.
The cell i tested i belive is a 100% geniune cell, i have pulled apart the cell to confirm, to see pictures of the cell i tested and striped look here (Manafont cell not DX)
Looks what a strange shape the plus pole has now compared to older pics in the thread, sure something is different in this new batch! Better or worse cannot say without testing, but sure they aren't the same they were before.
Just took delivery of two trustfires from ebay seller £10.88.and two from amazon £13+.
when my bt-c3100 charger arrived i decided to capacity test them just to make sure they are all around 4400mah.
To my amazement they are all 5000mah+….5166,5149,5208,and a shocking 5360mah.
not sure which battery came from where ,but if my charger is working correctly this would indicate trustfire have upped the ante on battery capacity/value.! not sure how to add photo,s but rest assured i took some .and will happily email attach.IMGP0737!
Greetings Darkness,
I thought I was losing it here.
Just picked up a pair of TF 26650’s from E-Bay for $15 delivered.
Charged and tested drain 2x with my iMax B6.
I ran 2 charge up and down cycles then did final tests on both.
Capacity was 5427 & 5398mAh for the 2 batteries at 1 amp draw down to 3.0v.
I thought my B6 was off….
I do have pics of the charge results I can try to get up, or I can E-Mail.
Cheers
added item 2-3-15: I noticed that my tested was stopping at 330 minutes. Found a cutoff timer was stopping test before complete. Changed timer to 360 minutes and capacities went up.
Added I-Max B6 discharge test pics with 360 minute timer:
