You should certainly get more than 10 cycles out of them. I dont have a definite answer as far as the dropping capacity goes, how do you know that theres the same amount of capacity in the cells each time before you commence charging ? I wouldnt run your car until it stops on the speedo voltage cutout if thats what you are doing mate ?
Because we race only 5 minutes we dont have a problem with capacity as a rule. When i race touring car stock class, a six month old pack feels a little less punchy than a new one. With buggies most of us turn the power right down to make them driveable so the lack of punch is less noticeable.
Personally, i change Lipos about twice a year. Thats not to say that they are spent when i do, i just feel its cheaper for me to sell them for half cost price and upgrade to a new pack for half the cost too. Lay out less capital at a time.
I wouldn`t store your packs fully charged, even if its for only a week. its not a big deal to charge them up before your race from 60%. it should only take around 25 minutes at 1C for your 5900 packs ( 5.9A )
