Discharging at 5A

So I am getting ready to store a few of my lipos. They are 2S 3800 30Cs. I have the cutoff set at 6.5v. Is there any harm discharging them at a rate of 5A?

If you're going to store them, your cutoff voltage should be more around 7.6V [3.8V per cell], but no problem discharging at 5A.

If a liPo pack is not going to be used for 5 days or longer, it is best to put a storage charge of approx. 2/3 of full capacity/voltage.

agreed on above.

Discharge at 5amp is fine but don't drop them to cutoff, leave 2/3 as stated. Some chargers offer a storage mode which calculate the storage charge per the mah selected and then discharge/charge to that capacity for you.
