2. using the cheap trust fire or ultrafire cells you are probably risking a fire as they are not really 5000 or even 10000 mah right now the max you can get in a 18650 is like 5000mah and that is from tesla. let alone a aa battery for consumer stuff.

   i think there is a reason that the new tesla cars use 21700 cells is because the can is bigger and can fit the battery material safely without cramming the space and risking fire or splitting the can

6. I have ultrafire bundled in a flashlight. Flashlight it self is great. But the ultrafire acu is literally empty inside if you cut them open

8. the highest legit rated cell is 3600mah. but they are only capacity not high drain, so you could not use it in a powerwall unless you have enough to keep the power draw in spec.

9. You liar! TrustFire has the real capacity mentioned, you skipped them from testing

10. Just sharing: bought some generic (#1) Chinese 18650 (no brand, dark violet color), (#2) some branded Ultrafire (exactly like the red one on the vid) and some looking exactly the same but branded (#3) "Ewtto".

    #1, terrible, worked so so at first then discharged by itself, heated while charging and wouldn't last.
    #2, surprisingly great, I must got a good batch, I know those shouldn't behave this good, lucky me.
    #3, not so bad… but then one of the batts died, won't charge and sometimes while no charge, will say it's 100%, absolutely garbage.

    #2 were the best ones and the cheapest in my experiment, still working great, charging and discharging daily. Don't take my word as an official reference because I think I just got lucky, plus I don't believe every one of those batteries are the same or manufactured by the same company. Anyone can put a logo there.

11. As seen on tv ads Taclight flash light. $20. Hmmm, look on Ebay, oh, almost the same thing $3. Needs a 3.7 volt battery, oh, here's one, Trustfire TF 14500, 900 mAh $2 Li-ion. Still better than the TV ad. So, 3 years and this battery I have charged once. No complaints.

12. UltraFire BRC 18650 4000mAh 3.7 V have worked well for me except my 165.00 dollar flashlight will not burn on the highest setting. Have recharged the 4 batteries dozens of times.
