Syonyk said:Yes, if you're using junk cells, you need to test them.
If you're using factory-new name brand cells, they should be fine.
Syonyk said:Up to you.
If you want to cycle brand new batteries a few times to validate them, go for it. I assure you, no major pack manufacturer is doing this, as the factory QC is quite solid.

Assuming, of course that nothing happened to them in transit, or they haven't sat on a shelf somewhere for a long time or they are not counterfeit or good cells are mixed with "B" quality cells by an unscrupulous seller.....all stories heard around 18650 batteries buyers/users.
So yes, if it is up to me I say two or three full charges and discharges, keeping careful notes on each cell capicity, then match them by capacity to give you optimal parallel groups to serialize.
