to have alot of people and post saying parrallel is better then series and why do i bother then the so called proof connecting batteries in parrallel with diffrence in voltage in the cells, then to use graphs and test equipment to prove us wrong but the info show,s there is a sudden discarge/charge from 2 to 6 amps between cells, then to say there it is parrallel is better and theres the proof.
high charge rates will add resistance to the batteries over time the high the internal resistance the less the amount of charge/discharge per cell, this can be from age/use or how the batteries have been charged and will affect how much current the cell can give and in time will lower the end voltage and life of the battery.
a 2c to 3c (3 x capacity) charge rate is no good for these cells or most other,s and in my honest opinion will add to the internal resistance of the battery, even if they are hitting 1.5c to 3c + for short periods, like parralle connection for charging while the cells self balance.
i belive no one yet has done a pretty graph showing the increases of internal resistance of batteries due to there use,s and chargine connection methods, but over the years of using batteries from an rc back ground of some 20 years and playing with diffrent chargine methods (high & low c rates, multible, series and parrallel) with lixx for the last 7 odd years ive noticed it wil, the high the amp,s you charge a battery the shorter the life, the higher the resistance gets.
and for the record you can series charge any thing and most premade rc packs are made in series and most chargers and made for series charging, some rc (hobby chargers) will limet the charge time and mAh because they are not suit to charging muiltible packs in parrallel (lostly large mah lipo packs) and you can even series charge lixx in series with out balancing if your in a rush, but balance charge is recomended.
just my 2 cents and not worth more as its just my thoughts and my expernce.
now back on topic i would love to test these batteries from the first post i was going to buy 3 till i got to the international shipping page $29.41 AUD each shipped to oz puts me off at thats almost 90 bucks for 3.
i was going to buy some aw,s recomended on CPF at $18.50 usd each plus shipping but that to put me off, ive read some info on the aw,s true or false

no i was stuck been witch batteries to buy so i brought some tf flames from manafont

i brought a couple to test out they took there claimed mAh rating they can take upto 5 amp draw and they are pretty consistance i brought more i now have 12 ive given some to my old man for a jet beam bc40 i gave him and a 2s (2 x 18650) balance charge lead i made and he is happy and 12 shipped was less then $120 aud.
im not say they are the best battery as they are not but for bang for buck if you get originals they are good, but is it worth paying the extra for these ? i mean two trust fire flames 2400mah at just under $11 each pair shipped at todays conversion or one Callie's Kustoms 3100 mah for $29.41 AUD each shipped to oz really worth the diffrence can the naked eye see the diffrence between 0.5 amp draw on high, i cant not on high.
at the price diffrence is it worth the extra claimed 700 mah as you could just buy more of the cheaper batteries to make up the mah, there has to be better more in the middle of the park if you get what i mean.
