I'm curious how much the C rating matters when you're only loading the battery at 5C or 10C or whatever. What I mean, is, does it matter more to mod racers than stock, since they put the batteries under more load? Or, does a higher C rating mean the batteries will hold more voltage under all loads, including the smaller ones. It's not clear to what extent, if any, it really means to the layman that's just running them with slow motors in club races.
I've heard it said before that C is mostly a marketing term, and is way too ambiguous (especially between different manufacturers) to really mean anything. I wish we had a way to test LiPo that could really tell the story about how the cells will react on the track in different styles of racing. I'm not convinced the standard 35A discharge like we use with NiMH is the best way.
