Just bought two of these to try in my 2X26650 unit. can't wait.

Thanks.

Norm,

Just to confirm, you mean to write 26650 not 26550, correct?

Post edited. Thanks for pointing it out.

If you check my posts I tested both of the new Batteryspace 26650 cells.

Just want to bump up this thread. I have been using the Keygos 26650 in my Keygos M12, M10, and just recently a Beamtech 4000 a 3x cree light. Not only do the Keygos 26650 run all my lights, that have good runtime also. In addition, I have seen tests on the Keygos 26650 that are rated at 4800Mah, to test out a 4000.

IMO, the Keygos 26650s are keepers and I just ordered a pair of Trustfire 26650. Hopefully I will get that same results.

Hi. I bought Keygos M10 (with T6 led), but batteries, which were with it, worked very short time (18650 Ultrafire 3800 mAh). May be some one can advise me which 26650 battery is better to use in this flashlight. Which 26650 is most reliable? And i wonder Panasonic, Sanyo or AW produces such type of batteries or not? Thanks.

I don't know if this light REQUIRES 3.7V Li-Ion batteries. But if not, there are always A123 Systems Nanophosphate cells. Voltage is only 3.2V nominal, which could be a problem if the light has low voltage protection and doesn't run cells in series. However, current isn't a problem, as they will crank out more amps than, well, anything else out there.

You guys also might want to check out this thread. I was somewhat frustrated with how the whole purchase of these went, since the only place they are available is direct from Germany, but on the positive side they do ship internationally.

I did some discharge tests down to 3.0 v under load, and my copies are 98% of rated capacity. They also sell a 4500 mAh unprotected 26650 cell which is a few mm shorter if length is an issue. We'll see how they hold up, but they look great out of the starting block.

Nailbender also sells some 26650's on his customlites site. They look like the King Kong ICR cells, but it doesn't really say.

Oveready sells a protected XTAR 26650 cell, I have been tempted to buy one just to see how it does.

On Vin's sub forum the Xtar 26650 did the best when various cells were tested in the X10vn.

I am awaiting an x3vn off vinh and did some research recently on cells,i ended up with efest 3.7 26650 rated at 30A

3500mah

On i4 right now ready


Until i get the light i wont be able to tell you exactly how good they are(notice the good):laughing:

Battery Space IMR 4000 mAh, MNKE IMR 3500 mAh, EnerPower Protected 4500 mAh, Tensai International Unprotected 4500 mAh

This graph is not completely apples to apples since the purchase dates on these cells is very different, and also note the discharge rate for the MNKE cell is higher (3.5 A) than the rest of the tests (2.5 A). Nonetheless it is a data point that might be helpful to somebody. The "Blue" are replacing the "Orange" in my inventory.
