Hi Gustavo. FYI. I have seen several of the 'flat' versions of "space qualified"  Lithium Polymer batteries fail for no apparent reason.

If you still have a choice, I would suggest the metal enclosed Li-Ion  18650 cells.   Never seen a failure with those and we've launched them on a Falcon 9, so Space-X are OK with them.  (JY1-Sat)

You may want to try AAC-Clyde for a Li-Poly data sheet. Or GOMSpace / ISISpace for a 18650.If you can't find the exact spec, you could always quote flight heritage using a specific battery supplier that they are familiar with. - However, that probably will not work if you've just purchased one off the shelf from Digikey etc.

Dear Group,

Our amateur radio team is currently building a cubesat, and I am seeking information regarding the Burst Pressure and Proof Test Pressure of LiPo batteries. Our launch provider, SpaceX, has requested these specifications.

These data points appear to be somewhat challenging to obtain. If anyone in the group has experience with a 3.7 V battery whose datasheet includes this information, your assistance would be greatly appreciated.

Thank you for your help.

Gustavo, LW2DTZ
