hello friends help me to define battery
I have a 450 size quad copter, which has 4 1000 kv motor rated 10 amp max, if i use 5.2 amp continue discharge rate lithium battery, how many batteries should i use to make 3s battery which can provide enough power to 4 motors?

Well it's not power calculation, to be clear.

You would need at least 10x3S battery packs in parallel, to be on the safer side. But infact, I would never consider making a lipo battery myself, when taking the risk into consideration.
Please don't do it, if you're new to batteries.
