Mam tut 4 nove panasonic ncr18650b z zascito.
I've got me a pair of this ones: http://www.banggood.com/1PCS-NR18650-30Q-3000mah-20A-Power-Li-ion-Battery-for-Samsung-p-981565.html Mainly because they are high drain and have a high capacity. I do want the max output, otherwise I would have bought another Nitecore P12 or something.
I think I will buy these samsungs, it’s time to try some unprotected cells
I just hope that my A6 or Xtar VP2 2 won’t explode or catch fire…. 
Do I have to do something to avoid these scenarios = how to handle unprot. cells)
Thank you
I’m somewhat new to this, but I run unprotected cells with a good (Xtar VC2) charger. The worst that can happen to me is I may ruin a cell by over-discharge which I can replace economically- nothing expensive can get hurt.
Same money for unprotected cell will get you a better cell since you aren’t paying for protection. This difference is more notable with high-draw cells that need high-current protection circuits. If money didn’t matter I’d use protected if they would fit the intended light for the extra “peace of mind” they offer.

I have a BLF A6 in transit at the moment. I own a Nitecore UM10 USB charger. Can u guys nominate a quality battery rechargeable for the BLF A6.
Use will be bulk lumens for short period/s.
Fast drain is not a problem.
Please recommend based on quality not price.
I prefer to buy from Banggood.
Also I have another flashlight for pocket EDC so conserving the battery power doesn’t come into it.
The Samsung unprotected 30Q or the LG HG2 would be good choices assuming you buy them from a reputable vendor. You have to be careful where you buy cells at example: LG HG2 counterfeit warning
Note: I recommend unprotected cells because the BLF A6 has under-voltage protection which will allow you to use unprotected cells with minimal worry (all Li-Ion cells have some risk period). If a light does not have under-voltage or over discharge protection I like to run protected cells for the peace of mind.
Quick question, I am also looking for max lumens for my BLF A6. Just how much improvement would a spring bypass cause, and how hard are they to install.
