Jim ... if a pack were to be pushed to its max discharge capability and always charged at 1C, it will give you about 60-70 cycles only. After that the performance is dismal. That is the reality of lipo technology. Read the manufacturer's data carefully, they ran the 200 cycles graph at a very low discharge rate. Many seem to say there is the magical 200 cycle life span for lipos, they however never seem to notice most of the test data was conducted at 2C-5C discharge only with a fading of 75%-80% after 200 cycles.

I have seen ESky El Cheapo packs being used for like 75-90 cycles and they are in good condition ... they were used in low performance set ups, hence they last.

I also noticed that the higher C packs drop off faster at the end. I have EVO20 5S 4,900 and the EVO25 5S 4,900 ... it was so obvious but I have no date to back it and again it might be the condition of the packs, I may have abused the EVO25s more. But I tend to feel the EVO20 running more consistently.

I have tested my 12T and I have 'cogging' issues at high RPM, first was the DS 90A ESC, the factory then tells me they have problems with the software. They gave me store credit. I did try with a HiModel 90A HV but she blew up, the sparks were nice. I am sure with a 20x10 I was only pulling 60A. Anyone know why the cogging at high RPM? Wrong timing setting or ...
