Hi,
i have a few questions about 18650 Cells
I have bought in March 22X 1830 accupacks from docterbass.
after disamble the packs, i have some round the 180 cells left.
after that i cycle(charger) every cell, then i discharge them to 3V - then charge them to 4.1V
the most of the cells come to 1200 a 1450 Mah, so i have make packs 6S with balance conectors and the most even capacity cells by each other.
So i had 3 packets of 6S10P so 14amp ... (i rode with 18S10P)
6S is the limited to my balance charger
BUT after some 15-20 cycles they are unbalanced....
now at this moment i have 14S6P
i have have this building with a new 100W soldering iron from Weller.
So what do i Wrong???????
i thougt that the 2second hand cells the problem whas?
Or must i every cell measuring @ interal resistance????
I whas positieve @ 18650 cells... but now i use most my HK lipo cells from my modelplanes...
Please some help !
