I always try to buy Panasonics or Sanyos but recently read about good cells with crap protection circuits. I think the Fasttech Pannys I bought were mentioned.

Do you have a source for that statement ?
Many of us have Fasttech panasonics.

It’s probably this thread

Reset tripped cell

I’m on vacation and brought along my SRK. In a hurry I just threw it in my bag without thinking to lockout. Pulled it out several hours and noticed it was warm. Tried to power it up and nothing. Tripped the protection circuit on 3 of the 4 protected NCR18650B batteries from Fasttech. Inserted batteries in my i4 charger and only one will charge. I’ve searched the forum, but haven’t found a reliable way to reset…

I have been reading a lot about fake cells in this forum. The concensus seems to be that *fire are in general crap. They are almost guaranteed to be fake with who knows what in the cell. What I do not understand, is what prevents the people who make these fake *fire cells, from makeing fake cells and wrapping them as green panasonics or as Sanyos or LGs etc. Why do those not get faked?

Another question for the experienced. FastTech list the actualy capacity under the description of most cells. Is that info reliable? For example in the description of these 3600mah FandyFires it says “real capacity 1300mah”. http://www.fasttech.com/products/1420/10000992/1083700-fandyfire-18650-37v-3600mah-ptrotected-rechargeabl
