I was charged double shipping for my protected panisonic cells since i only brought two im not sure if this is normal or not.
If thats the case i was much more impressed with the protected redilast 2600 mAh batteries, since the cut off is 2.75 volt i feel they have slightly more usible voltage to me.
They still give over 2400 mAh discharged at 5.2 amps to 2.75 volt and 2500 mAh discharged to 3 volt at 0.5 amps.
Im still yet to do more discharge test's to 2.75 volt, but they have great protection but cost around $3 usd more cause of the international shipping to Australia.
The way i see it there protected panisonic cells cost me $31 usd shipped for 2 (and they failed in my opinion)
The redilast protected 2600 cost me $34 usd with international shipping for 2 (they are cheap shipped inside the usa)
The good protected trustfire flames cost $33 usd shipped for 6.
The unprotected panisonic cells are great just not the protected cells, but will they last 3 times longer then a protected trustfire flames cell to reflect the price, im not sure as even your self your still testing flames that are 12 months old.
So will 1 protected panisonic cell last 3 times longer then one flame, maybe if the panisonic,s pcb does not fail and the other way around, but i think 3 flames for the same price as 1 protected panisonic, will last just as long or longer and will give more run time combined and 3 cells would not be worked as hard as one.
Even the cheap trustfire flames i tested give 2500 mAh when discharged to 3 volt at 0.5 amps, but they do not rate as good as the panisonic,s at higher discharge test, but since im talking about the protected versions that will not do high discharging that does not matter.
The trustfire flames do actualy give more mAh and do not trip at 3 amps then the protected panisonic,s i tested, but they might not last as long but you can buy 6 for the price of 2 protected panisonics pritty much, 6 batteries would not be worked as hard as two batteries one would think.
Now like i said the unprotected panisonic cells are good, Hank from int-outdoor is good, but i can not recomend these in protected form as there is a good chance people want more then 2 amps from them, but they dont sell the protected form any more, im sure the new ones they will sell in the future will be better but will most likely cost more.
Im just trying to add some prospective and not let my full refund so basicly fee cells sway my opinion on the cells.
Unfortunaly we know why one cheap mosfet thats not capible of high discharge rates.
