Parallel with only two cells ? That is not very safe. It might not even have an advantage.
I'm sorry, but I don't know a protection board for that.
This is typically a question for: www.eevblog.com/forum/
Two raw cells can be paralleled just fine, they just need to be of same chemistry and somewhat same voltage (within 0.5V) when connected together.
Connect the protection board AFTER the two cells that you joined. Two cells in parallel will act for all intents and purposes like a single cell, just with a higher capacity.
