I have a 35 gfx and was wondering if i can go through my old packs and look for a couple good packs. I have at least 6 old packs of 3300's and 4200's. I bought the single cell holder to put them in. My questions are the settings to do this. I use the cycle program to match the cells? Check the data at the end and write that on the cells? Also how many cycles to i put them through and how long of a cool down between cycles? Any info would help. Now i am doing a 30 amp discharge with a 6 amp charge and 3 cycles with a 10min cooldown between them???
