what battery you suggest me??

15

Panasonic 3400mAh. HKJ test. Panasonic 3400mAh with quality protection Panasonics are very reliable. Often regarded as best brand for li-ions. No one else can even make a true 3400mAh 18650 and they just started production of a 3600.

HKJ’s UltraFire BRC 3000mAh tests showed actual capacities between 2094-2610mAh (at 0.5A). Anywhere from 4 to 6 panasonics will give the same or better runtime as those UltraFires.

i need 100 euros for 7 of these… :frowning:

17

4 of them may be enough to give better runtime then 7 ultrafire BRC. And panasonics won’t blow up on you while your deep in a cave.

HKJ's Ultrafire have a high capacity abnormal for that brand, generally you have under 1000mAh. However capacity is such an insignificant problem of Ultrafire. The cells are dangerous.

20

ok :frowning: now when i have more than 20 of thees i made this one with them… but for my next project i tray to by panasonic or sanyo :slight_smile:

21

You know I saw that thread & have even linked to it! Yet somehow I forgot it was mostly ultrafire BRC in that thread. :weary: :~

At under 1000mAh for each ultrafire… 2 panasonics would give better runtime then 7 ultrafire.

22

Just saying that HKJ's test is irrelevant considering that we could pile up tons of information on Ultrafire, BRC, LC, XLS, doesn't matter.

what do you think about this driver?
i can’t order from those sites that you post…

24

Yeas indeed.

But that does not matter, since you do not know when they give up on you, it's not like they are new, or real 18650 1000mAh cells. Safety first since we know capacity is something unrealistic with Ultrafire.

Good driver. You can get a single one from kaidoman, they ship internationally. KD 8x7135 V2 LED Driver 3040mA 17mm $4.79

26

I believe hes looking for med,high. KD 8×7135 V2 says it does med,high. The fasttech one is low,high instead.

Forgot to comment that your battery case is really nice. Could get over 18 hours driving an xml at 1A with 7x panasonics.

Waterproof wiring bulkhead connectors will improve the water resistance of that power wire
