hello everyone. I am about to buy a protected battery for the blf a6 (my first 18650 flashlight) and i am between NCR18650B, ICR18650 - 30B, UR18650ZY and ICR18650 - 26FM and i want to ask if they can handle the current for the turbo mode (especially the first cell). Any other suggestion?
Well, if it were me, I would be buying UN-Protected batteries. And that is bacause now I have learned how to manage them. I use quality chargers, Xtar and Nitecore, and I ensure they cannot short-circuit.
Do not skimp on buying your charger. A quality Li ion charger is important for you safety.
But for a protected one, the NCR18650B battery will do nicely for you. That should provide plenty of amps for that flashlight.
The BLF A6 has built-in over-discharge protection IIRC, and therefore does not need a protected cell. It also performs better with cells meant for high current draw and some protected cells will not deliver that level of output. For this light a hi-draw un-protected cell will give you best performance but it will work on any that will fit. Which some protected cells will not fit; that can apply to many other lights so it’s not a shortcoming of this one in particular.
Others can give specific recommendations but I’m happy with my IMR 2500 Efest’s, a slightly noticable difference from the Samsung ICR 32A’s I had been using.

IF I where going with a protected cell, I would choose one with a sanyo NCR18650GA inside.
For example the KeepPower 18650 3500mAh has a NCR18650GA inside.
The Sanyo NCR18650GA is a 10A capable cell with a high capacity.
I use one with a Fet driver (the same one as in the BLF A6) and around 5A.
You don’t need a protected battery.
I think Samsung 30Q, LG HE2/HE4, LG HG2 are the best candidates for BLF A6.
Also, if you want more capacity there are SANYO GA and LG MJ1.
Thank you for your answers. Because it will be my first li-ion battery and maybe i will use it and with other flashlights, i would like to be protected. The NCR18650GA looks great but i can not decide between keeppower 3500mah 1PC KeepPower P1835J 18650 3500mAh 3.7V wiederaufladbare Batterie Sale - Banggood Deutschland-arrival notice-arrival notice
and olight 3600mah http://www.banggood.com/1PCS-Olight-3_6v-3600mah-Rechargeable-Protected-18650-Lithium-Battery-p-984322.html. There is a difference in price but i like to be 100% safe.
same driver in a custom modded AS31 that TomE built for me and with the Samsung 30qs He was getting aroundOhh – that was on a HE2 @4.21v, 5.09A tail reading…. The HE2 is bout the same as a 30Q, of course a GA cell will be less – think I posted #’s on that tooE built for so just what was recently shared with me and o am passing it on hopefully it will help.
I recall someone cautioning that the protected cells may have their protection tripped by the high-amp draw.
Not a problem, but if your light goes to zero all of a sudden, reset the protection on the cell.
You will not get anywhere near the output that your A6 is capable of if you use a protected battery.
Please, he asked for a protected cell, let’s not all try to push him to unprotected cells 
I have used both kinds in the A6, and max output will be somewhat higher on, say, a 30Q but not so noticeably to rule out a protected cell (and spring bypass shall be applied for the high discharge to be fully available). A protected cell with a good discharge capacity will get you satisfied just as much, and gives peace of mind.
Not the Olight. Its protection circuit is a poor performer, has high resistance. Use Keeppower, Eagtac or EVVA 3500mAh instead.
Not to bring an old thread back from the dead… but I am.
New guy here with a question about the best (subjective, I know) battery for the A6 now that it’s been out for a while…
I’ve got one coming on the slow boat from China due to a year of Cone bragging about how great it is.
I’m fully aware and prepared to deal with an unprotected 18650 and it’s my understanding that turbo mode is direct drive.
Having trouble searching for the specific thread where the current draw of the BLF SE A6 is stated.
SO, all that said…
What is the highest capacity 18650 battery that will be able to handle the amperage of the A6 in turbo mode???
Thanx in advance for your advice.
I would say either the LG2 or samsung 30qs all 3000mah storage with high amperage of a out 20+ Amps
That’s one of the few on my short list…
Thanx for the reply.
LOL, “Cone” who?
Welcome to BLF, my old friend.
Thanx…
Didn’t know if you’d see that here or not so I brought up the subject elsewhere.
Still learning the ropes around here, but I’ve been lurking for a bit now.
I just keep getting deeper and deeper into the flashlight world…
I would say either the LG2 or samsung 30qs all 3000mah storage with high amperage of a out 20+ Amps
LOL, I see everything.
hi there! this thread of mine might help
I think these protected Sanyo NCR18650GA should meet your needs.
I asked LiIonWholesale.com about them.
