Hello,

I'm developing a product that I plan to use as battery 2 x Li-Ion 10440 cells.

Now, each battery on their own is certified for EN IEC 62133-2 and UN 38.3.

The question is, if I use two of them in parallel ( basically a package ) I will need to redo this certs again for the whole package ? That would cost thousands / tens of thousands... :|

Can you guys please bring some light on this matter. Thanks a lot !
