I don't think I can name any company who's gone to such extremes to please customers before.
RPM. Nuff said.
That sucks that you are having so much trouble! I run a 3200mah 2s hardcase with probably 30 cycles on it and it is fine. Maybe try some other brands? I leave my lipos charged for a few days at a time semi often and never have problems.
I dunno, i've heard lots of people get declined service because of all the red tape and "standards" to be met that RPM requires before they will replace a part free.
